The post copied below says the end stops only work for homing. Im having an issue after flashing my Rambo 1.4 to Marlin 1.1.9 with dual endstops and LCD support. Locate the lines #define TEMP_SENSOR_N where N = number of the extruder (0-2) or BED for heated bed. The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). I did end up disconnecting which stopped the motors but when I reconnected it started up anew. I finally got my MPCNC built after several months of start-and-stop work, and it made a pretty respectable crown test drawing!. This was without ANY USB plugged in and using the touch screen to move. A second issue I have, is that after homing (which works fine) the config flag “move_to_origin_after_home” is ignored / not executed. Then, if the endstops show as triggered all the time, your endstops are probably not 3.3V compatible and you need to modify them - see Connecting endstop switches. How to calculate charge analysis for a molecule, Don't understand the current direction in a flyback diode circuit. When I send an M119 (endstop status code) I recieve: And then when I press down the X endstop with my hand I get: -No change. Issue the command M111 S247 to enable maximum logging. It’s something that is being actively worked on. beta_limit_enable false # set to true to enable Y min and max limit switches I am having problems with my Y endstops from working . I have a couple of questions though. My X and Z endstops work Perfectly. Moving the origin in your CAM program is the easiest fix. #define max_software_endstops true. If you have any endstops not behaving you turn off the printer, unplug the USB and Check the pin-connection.Correct as nesccesary. Marlin’s extruders=0 or remapping of pins is used in the firmware to allow the use of all the control boards drivers. The way this is done is by homing the machine so it knows where it is. These are mechanical Makerbot 1.2 endstop switches. To learn more, see our tips on writing great answers. Re: (Kossel) Alpha axis crashes into end stop AFTER successful homing What sort of work environment would require both an electronic engineer and an anthropologist? Bed Leveling is a standard feature on many 3D printers. Im finally getting around to setting up my Mini Kossel. Enable DEBUG_LEVELING_FEATURE and M114_DETAIL and re-flash the firmware. #define min_software_endstops true. when you hit an endstop in max, you cannot go any further forwards, but you can still operate and go backwards. I need the endstops for homing AND to let the board know when it has reached the start of the axis, and that the other end is 200 mm in the other direction(software endstop). Endstops will not trigger using Marlin Firmware, Podcast 302: Programming in PowerPoint can teach you a few things, Useful things to check for when cleaning up posts, Using an Arduino Mega with burnt voltage regulator. gamma_homing_direction home_to_min # try uncommenting the following lines to enable endstop detection on all pins for troubleshooting. Glad to hear that things are moving along. to invert if endstop is NO connected to ground 1.1.7 debug HAS_TRINAMIC_CONFIG ... sdcard HAS_SPI_FLASH SDSUPPORT MARLIN_DEV_MODE M993-M994 - SD / SPI Flash. This is functionally identical to “hitting the actual endstop stops the axis”. gamma_min_endstop 1.28^ # with mechanical or optical end-stops) is mandatory while building printers. Are Random Forests good at detecting interaction terms? As said before, I need the endstops for homing AND to let the board know when it has reached the start of the axis, and that the other end is 200 mm in the other direction without coming to a full stop because the end stop was hit. It turned out to be a combination of those lines being commented out and the end stops were connected to the wrong two pins. … worse for max_endstops : even triggered, it tries to go further, hitting the max_endstop does NOT even stop the movement, and does NOT protect the printer. Yes, this is not supported. I am using a regular limit switch with NC going to the signal pin and the other to ground. I clicked the z-axis movement in Pronterface many times to get it to the endstop and my machine runs the y axis into the bed nonstop until it ripped the couplings off the z motors. I found the way the limit switches are implemented (machine full stop) to be overly dramatic for my use case. beta_homing_direction home_to_max # I feel that the machine has a nebulous idea of where the machine is at. Unfortunately, the method I proposed above does not work. EDIT: About drivers. I have everything but two Anyway, I’m trying to get it working again, and since you say that it works (“which Smoothie can do.”), I would be glad to know what I need to enable/activate to do so. There is a spec here that explains a bit : https://docs.google.com/document/d/1U6nzx1boqF-J2GGPWF4yIaaVib0JNodVWSKBfwiyp_M/edit#. Solved I have Jumper on XST and YST. In Pronterface I couldn’t find a stop machine from killing itself button. Thanks a lot. Then the machine is able to ignore moves that would go out of the machine area. Could you please explain what I should do ? Software end-stops are enabled by default. The unused extruder driver/s are used for the extra stepper/s. May be there is an explanation for this behaviour, I would be glad to know it, could someone explain that ? I used the 2.00 pin on the SKR 1.3 and im going to use the 0.10 pin on the SKR 1.4. Soft endstops is in a separate branch for now because it’s not documented yet, but we expect it’ll get integrated very soon ( we looked at it just a few days ago again ). Connect to your printer from host software such as Cura, Printrun or Repetier Host. fly wheels)? The travel distance is not calibrated yet and the practical distance will be different than the calculated distance. Don’t go beyond the maximum limit. beta_max 200 # BUt Y does not . As supplied, the endstops are only configured as home switches, in effect, once triggered, you can manually step, or drive the head past them. What else would you expect machine to do if your code try to operate outside of machine range (hence the code is obviously generated wrongly). Have you been able to implement endstops similar to the way they work in Marlin? Apparently it is a bug for MAC but i am using WIndows 8.1. Hello all. However, you can use the soft endstops feature ( with the halt option disabled ) to tell the machine to stop when it’s at the end of the axes ( so you can set it up so it stops right before the endstop ). I worked on number of big professional cnc machines and when you issue a move that goes outside of the workspace every single one of them will halt and turn on the warning light?! I have even shorted the signal and ground pins on the Ramps board with a jumper wire and I still haven't seen any change. I have searched and read lots of posts but nothing fixed the issue. halting the entire printer is not what I want : I just want the axis to stop at hardware endstop and do not go further on the endstop direction if triggered … Printer moves korrekt, but even software endstops won't work. Please, update your documentations, state the things has they are not has they will in a potential future, and don’t leave misunderstandings on it. I have had my 5x board for a while now because everything can make it blow up and I didn’t feel there is enough information to get it right. "it is possible that the endstop pin on the Atmel chip is not working anymore. No dishonesty there, just a lot of hard volunteer work. That means the z endstop pin doesnt work. Making statements based on opinion; back them up with references or personal experience. Disable endstops and keep them enabled when not homing. When software end-stops are enabled, the home offset will not work outside the axis travel limits. I have took a look to the limit_enable thing => it is clearly too drastic ! Is the line uncommented ? Printer area. TO further test, I tried ALL of the motor axis and they all move when holding the same endstop, so its not just that I have them crossed. I am using the dc42 fork of RRF, and I must say, if you're reading this, dc42, your work on the firmware and PanelDue are absolutely fantastic. To test, I have pressed one of the endstops with a finger and have … MathJax reference. -Not very good for a kill switch really. On solidoodles board the + and - are reversed for the endstop connectors by default. If I am wrong then the machine tries to make it to 200mm by brute force! You’ve been very agressive towards people who are giving you their free time as a present, I can’t understand it, and I think you need to read : http://smoothieware.org/troubleshooting#i-m-very-upset-at-something-everyone-is-mean-and-nobody-listens-to-me, Powered by Discourse, best viewed with JavaScript enabled, https://docs.google.com/document/d/1U6nzx1boqF-J2GGPWF4yIaaVib0JNodVWSKBfwiyp_M/edit, http://smoothieware.org/troubleshooting#i-m-very-upset-at-something-everyone-is-mean-and-nobody-listens-to-me. How to symmetricize this nxn Identity matrix. I’m using a Ramps 1.4 board with the Marlin-MPCNC_Ramps_T8_16T_LCD_32step_DualEndstop firmware. hi i … PS: @Dytoractor : did you found a way to avoid this ? After firmware (2.0.7.2) is uploaded, I experience 2 issues: The LCD is showing 2 lines of squares where I expected the Marlin logo first and then the default home screen. @Ulysse31 I’m confused about what you are trying to achieve and would really like to understand the rationale behind your request?! beta_min 0 # If they never show as triggered, check that the flag on the end of the axis blocks the slot completely, and that there is a pullup resistor between the sensor … the y axis works perfect. This is great, following what is written on the documentation, it seems to do exactly the expected behaviour I was talking about ! The endstop did not stop any movement in any direction. alpha_homing_direction home_to_min # or set to home_to_max and set alpha_max I think I had the wrong idea of what an endstop did as well. For other boards you may need to define FIL_RUNOUT_PIN. updated the mks firmware bin to smoothiewares edge. Also, the buttons are not responding to clicks and turning the main knob does not work either. Does that answer your question, or was there more to it ? You can connect two motors to a single driver, that’s no problem, it’s how most people do it on i3-type machines. Most additions to the wiki are related to requests by users, every time I see something that isn’t documented and that is talked about in a forum/mailinglist/G+ etc, I try to add it to the documentation. beta_min_endstop nc # Also check for continuity again, using a multimeter. This command can be used to enable one or more steppers (X,Y,Z,E). can you help me… i suppose is in marlin but i can’t find the problem. Can an exiting US president curtail access to Air Force One from the new president? The version of Marlin that I use (Bugfix 2.0x (and all other current versions I presume)) **doesn’t react to a Stop command until after the current move has completed. load or back up SPI Flash and SD. So from this conversation, I am understanding that only Homing works? The endstops are wired NC -> top To subscribe to this RSS feed, copy and paste this URL into your RSS reader. UPDATE: HURRAY !!! Depending of the firmware version of your Marlin, in some cases it gives issues, but if you connect to ZMin it will work perfectly. Marlin has the dual endstops. Same problem here for me as @Dytoractor, I have 6 Normally Open (NO) endstops (one at min and max of each axis), configured with “!” in order to be inverted. I have everything assembled and wired up. Will it burn up the driver if I connect both motors to the same driver? gamma_limit_enable false # set to true to enable Z min and max limit switches. As expected things go wrong. If the seller is unable to help you, feel free to ask again here. If yes, why is it not simply and clearly written like that on the documentations ? The console got the commands and and it looks like it should have moved. Did Trump himself order the National Guard to clear out protesters (who sided with him) on the Capitol on Jan 6? By reading the documentation, we can deduce that software end-stops are not implemented (by soft end-stops, I mean what any other 3d printer architecture means : limiting max distances), BUT, hardware end-stops (limiting movement by hardware eg. alpha_min 0 # this gets loaded after homing when home_to_min is set alpha_max 200 # this gets loaded after homing when home_to_max is set Implemented in many other firmware like marlin or teacup …. My endstop configuration is currently: I have X-min enabled and inverted. RAMPS-based boards use SERVO3_PIN. Plugging them in in the max endstops does show change when they are pressed with M119. All 4 files are also in the attached Base config (Z-endstop only, no BLTouch, homing at X=0, Y=0).zip file, the configuration in them matches the config in Option 1. site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. If I get this figured out, I am going to buy a board from you guys to put in my k40 laser. First, my endstops are supposed to be working properly (checked with M119), but when homing one of the axis’ (random) will just keep going and crashing into the endstop. The pins in pins_MKS_SGEN_L of marlin also appear to be correct since the assignments is: X_min_pin P1_29 Y_min_pin P1_27 Z_min_pin p1_25, So those appear to be correct. If you don’t find them to be don’t hesitate to ask further questions. calibration TOUCH_SCREEN_CALIBRATION I have tested that my endstops function by sending M119 and verifying that the endstops correctly show OPEN or … Here is the boilerplate: Download Marlin bugfix-2.0.x to test with the latest code. I uploaded the standard delta marlin and when I go to home the axis', they keep trying to move up after they trigger the endstops. gamma_max 200 #, #homing_order XYZ # x axis followed by y then z last, alpha_limit_enable false # set to true to enable X min and max limit switches I just set up a MKS SBase 1.2 I have everything figured except for two things. Have you implemented the functionality you referred to earlier in this tread? How do others use this correctly? I home it and it finds a corner… then in the config file I say it is 200mm from the home position. Since this project is not new (smoothie is around for about 4/5 years now), why is it not simply stated like this on the documentation ? Initial script (GCODE commands) halting the entire printer is not what I want : I just want the axis to stop at hardware endstop and do not go further on the endstop direction if triggered …”, "A reset will be required to continue, or sending M999, make sure you move away from the endstop though before trying to move. I have this switch plugged into first header column for X-min. If you where to cut out that part it would result in going negative past your endstops and misalign your machine. Thanks! I'm frustrated. My config can be found here: pastebin.com / zJZ4SLBx, endstops_enable true # the endstop module is enabled by default and can be disabled here That’s just a guess.

Is this true? 3D Printing Stack Exchange is a question and answer site for 3D printing enthusiasts. If the status does not change when activated it is most likely due to bad pin-wiring on Ramps, but it can also be the firmware. If I disable the 3 “limit switches” lines, it goes back to not stopping when the switch is hit. The only thing I can think of is that either the switch is plugged into the wrong pin on the ramps board (Max instead of Min) or the switch doesn't require the pullup (your could try commenting that back as a second test as well). UPDATE2: lol … looking to the revisions for the endstop page documentation is … hilarious … modifying it and adding soft endstops, and simply replying here “which Smoothie can do.” without any “Hey we added the feature”, or “hey we updated the documentation” … no simply a “smoothie can do” … that’s not really a honest behaviour …, So I’m not honest now ? I just set up a MKS SBase 1.2 I have everything figured except for two things. Marlin has support for four temperature sensors (three extruders, one heated bed). Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. a logical comparison agains a stored min and max value (set on homing) which prevents the machine over- and under-running its axis dimensions? Are you using the latest firmware ? It might, but the motion feedback in grbl is totally different. the TL:DR is that found that a 2 wire mechanical only has the 3.3v from the endstop plug on the SKR and the TMC diag pin but the 3 wire mechanical endstops use the 5V pin which is not only used for the LED its also raises the signal voltage to 5ish Volts but since the SKR is held at the 3.3volt from the TMC. gamma_max_endstop nc # Homing functions works correctly, BUT, after homed (all home_to_min, so min_endstops are triggered), if I ask the printer to go further backwards … it tries to go further even with the endstop triggerred (which, for me, is a complete NONSENSE! ) A caveat, you can resume the program (play), however the carriage that triggered the limit, will continue on through the limit switch, also, all endstops will be disabled at this point, until the printer is reset. When I home (in Pronterface Here) in the Y direction its as if the endstop is not even connected no response form the switch. Still not a complete and straight answer, but, we can deduce the following : to resume, FOR NOW on smoothieware, hardware endstops only work for homing action, or as a kill switch. Enable endstops and keep them enabled when not homing. How to find out if a preprint has been already published, Piano notation for student unable to access written and spoken language. this is 3d printer hardware protection basics. I currently don’t have the LCD, could this be preventing it from working? youtube . Or if I click the move motor buttons pronterface will move it to whatever I want regardless of a switch. move_to_origin_after_home worked last time I tried it ( and it was with a beta axis homing to max too ). Thanks to #7470, #define ENDSTOPS_ALWAYS_ON_DEFAULT is always uncommented (enabled). What would you expect on a mill or a fdm printer to do for a move that goes outside of the workspace? Testing repeatability of the probe. bon courage, has there been a solution to this i have same problem Make sure your job has a work offset if you use the endstops. I have an old Solidoodle 2 that I bought broken from a garage sale that I am converting to use RAMPS 1.4 with Marlin Firmware. http://smoothieware.org/endstops#limit-switches. The thing is : it’s much more difficult to implement than it seems ( or it’d be in already ). If I would have homed the Z axis instead of clicking it many times it would have stopped my machine? on the axis’. In the meantime, if your machine is capable of harming itself, please install min and max endstops and enable limit_switches. I wanted to get a status on the progress in the area of the endstop functionality. you need to ether remove the resistor, which is really hard or asign another pin to the Z endstop and put the signal cable of your probe to this pin. He wants the machine to ignore any command that would take it outside the work area, which Smoothie can do. First, my endstops are supposed to be working properly (checked with M119), but when homing one of the axis’ (random) will just keep going and crashing into the endstop. I've tried changing home position. Im using CNCjs and it seems to connect fine but when I go to move it though the GUI it doesn’t move. tailgunner30uktailgunner30uk 12 Aug 2014, 12:50 com / watch?v=r8IndlYyA_0 (remove spaces). If we want the axis to travel to maximum position plus home offset, we will need to disable software end-stops. If you want to control Marlin from a tablet, run octopi on a raspberry pi. All the motors work correctly, I am just having issues getting the endstops to work. I take marlin with double endstops and i can move all axes but not Y2 and Z2? What you can do is to use the MAX endstop pins for the X endstop by defining the X endstop using the pin of the MAX endstop. If you enable an axis with limit switches, you also need to ensure that the axis-minimum is set to NC to avoid a false trigger of the limit as the carriage is backed off the switch. I have an old Solidoodle 2 that I bought broken from a garage sale that I am converting to use RAMPS 1.4 with Marlin Firmware. I finally said screw it, if I break it I break it! I have edited the config and tried with and with out the ! I have searched and read lots of posts but nothing fixed the issue. Thanks for replying, but, like I already said on my last message : “I have took a look to the limit_enable thing => it is clearly too drastic ! Could the US military legally refuse to follow a legal, but unethical order? alpha_max_endstop nc # NOTE set to nc if this is not installed How far would we have to travel to make all of our familiar constellations unrecognisable? I've attached a copy of my Marlin configuration.h file. You can have “hitting end of axes causes the movement to be ignored”, which is what you asked for ( correct me if I misunderstood ). Work offsets. Thanks for contributing an answer to 3D Printing Stack Exchange!

So “universal” way is to put in an optocoupler which is not only working but protects your board from damaging Sensor support. In the case that connecting the 2 wires to the Probe connector the sensor not works, try to connect to the ZMin connector. Having my beta-endstop at the max position of my Y-axis I would love to see the bed moving to its logical origin. A friend sent this board to me, I thought it was going to be a real SmoothieBoard until i took a look at it. If I enable the 3 “limit switches” lines, the printer does stop when the switch is hit, but then I have to reset. In reading posts on the forum about endstops, it looks like endstops on Smoothie may not work the way I expect them too. beta_max_endstop 1.27^ # This is sad… and dangerous for the mechanical integrity of a machine… This should be implemented asap!!! @arhi: what I want ? » is incorrect. Really? Asking for help, clarification, or responding to other answers. If they are optical endstops, first make sure that you have S1 in the M574 command. it will only lead people to feel fooled once those kind of troubles are discovered. (I do not understand all the terms.) it is simple => a 3d printer behaviour (not cnc) => on any axis, when you hit an endstop in min you can not go any further backwards, but you can still operate and go forwards. Because, for now, after homing all the axis (which it does correctly, stoping once hitting mins endstops), if I say to smoothie to go backwards on any axis (which obviously physically cannot do since it is on the endstop min) it still force like a dull, by the way eating my belts on the motors pulley teethes … same for max endstop. There is no mechanical failure with the switches, I've tested it with a continuity tester. I've checked M119 and all three of the endstops show to be triggered when manually pushed. optional order in which axis will home, default is they all home at the same time, if this is set it will force each axis to home one at a time in the specified order, optional enable limit switches, actions will stop if any enabled limit switch is triggered. Hi, I have been scouring the internet for weeks trying to get my Arduino Due + RADDS 1.5 + PanelDue set up for my Kossel printer. control M121 - Disable Endstops. I may understand that software endstop are not yet implemented, BUT, AT LEAST, is it possible to have hardware endstops working correctly ? Obviously there are many people with problems using TMC2209 with sensorless homing. I have endstops that I bought from makerbot because they have “protection” and let me know when they are triggered. If you configure them as limit switches then you cannot step past them once triggered. So to make it clear: Smoothieware does not support software endstops aka. Connecting Sain Smart Mechanical End Stops to Ramps 1.4? Angular momentum of a purely rotating body about any axis, Ceramic resonator changes and maintains frequency when touched, White neutral wire wirenutted to black hot, Get app's compatibilty matrix from Play Store.
