marlin endstops not working

Im using CNCjs and it seems to connect fine but when I go to move it though the GUI it doesn’t move. 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. I have tested that my endstops function by sending M119 and verifying that the endstops correctly show OPEN or … If we want the axis to travel to maximum position plus home offset, we will need to disable software end-stops. 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. 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've checked M119 and all three of the endstops show to be triggered when manually pushed. You can have “hitting end of axes causes the movement to be ignored”, which is what you asked for ( correct me if I misunderstood ). If you have any endstops not behaving you turn off the printer, unplug the USB and Check the pin-connection.Correct as nesccesary. Locate the lines #define TEMP_SENSOR_N where N = number of the extruder (0-2) or BED for heated bed. It only takes a minute to sign up. I just set up a MKS SBase 1.2 I have everything figured except for two things. The hard endstop result in a halt state yes, which then requires M999 to get out of. 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. 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. Making statements based on opinion; back them up with references or personal experience. In the case that connecting the 2 wires to the Probe connector the sensor not works, try to connect to the ZMin connector. 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. It can be caused by static getting into the pin from the endstop wiring, Ive seen a few of these happen on X3s and X3 Pros. 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. To learn more, see our tips on writing great answers. For other boards you may need to define FIL_RUNOUT_PIN. Initial script (GCODE commands) There is a spec here that explains a bit : https://docs.google.com/document/d/1U6nzx1boqF-J2GGPWF4yIaaVib0JNodVWSKBfwiyp_M/edit#. We do not have software endstops, we are working on implementing those ( it’s more complicated than you’d expect, it’s the only major feature we are still missing ). load or back up SPI Flash and SD. A typical part has the gcode built with the origin at the parts corner. To test, I have pressed one of the endstops with a finger and have … 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. 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. Anet A6 Z-axis min endstop not triggering, Z-axis endstop not functioning after Marlin Firmware installation, Limit Switch problems on RAMPS 1.4 and custom built 3D Printer running Marlin 1.1.0-rc6. This issue cannot be closed. Depending of the firmware version of your Marlin, in some cases it gives issues, but if you connect to ZMin it will work perfectly. beta_min_endstop nc # beta_homing_direction home_to_max # If they are optical endstops, first make sure that you have S1 in the M574 command. 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. 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. No dishonesty there, just a lot of hard volunteer work. bon courage, has there been a solution to this i have same problem 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. 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 ? That’s just a guess. Can an exiting US president curtail access to Air Force One from the new president? All the motors work correctly, I am just having issues getting the endstops to work. BUt Y does not . when i try to auto home my printer via LCD or in the software it seems that it totally ignores the endstops of the x+z axis. How can a non-US resident best follow US politics in a balanced well reported manner? Implemented in many other firmware like marlin or teacup …. RAMPS-based boards use SERVO3_PIN. It might, but the motion feedback in grbl is totally different. alpha_min_endstop 1.24^ # add a ! A second issue I have, is that after homing (which works fine) the config flag “move_to_origin_after_home” is ignored / not executed. Marlin indicates this by blinking question-marks in place of X, Y and Z on the LCD screen (v1.1.8 and older) or blinking ‘?’ in place of the coordinates besides X,Y and Z (Marlin v1.1.9 / v2.0.0 and newer). Then the machine is able to ignore moves that would go out of the machine area. Will it burn up the driver if I connect both motors to the same driver? What sort of work environment would require both an electronic engineer and an anthropologist? Si je puis me permettre d’après votre fichier config vous n’avez pas de butées beta mini donc pour la prise d’origine je pense que cela doit poser un problème pour le réference de vos déplacements, je dis peut être une co…….! #define max_software_endstops true. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. I did end up disconnecting which stopped the motors but when I reconnected it started up anew. gamma_min 0 # In the meantime, if your machine is capable of harming itself, please install min and max endstops and enable limit_switches. The unused extruder driver/s are used for the extra stepper/s. I am having problems with my Y endstops from working . What are the earliest inventions to store and release energy (e.g. rev 2021.1.8.38287, The best answers are voted up and rise to the top, 3D Printing Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us. It turned out to be a combination of those lines being commented out and the end stops were connected to the wrong two pins. Unfortunately, the method I proposed above does not work. All the motors work correctly, I am just having issues getting the endstops to work. I am using a regular limit switch with NC going to the signal pin and the other to ground. gamma_homing_direction home_to_min # This is great, following what is written on the documentation, it seems to do exactly the expected behaviour I was talking about ! The thing is : it’s much more difficult to implement than it seems ( or it’d be in already ). when you hit an endstop in max, you cannot go any further forwards, but you can still operate and go backwards. Bed Leveling is a standard feature on many 3D printers. If you configure them as limit switches then you cannot step past them once triggered. I have a couple of questions though. 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. I currently don’t have the LCD, could this be preventing it from working? How to find out if a preprint has been already published, Piano notation for student unable to access written and spoken language. 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. a logical comparison agains a stored min and max value (set on homing) which prevents the machine over- and under-running its axis dimensions? 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. I've attached a copy of my Marlin configuration.h file. alpha_homing_direction home_to_min # or set to home_to_max and set alpha_max This is sad… and dangerous for the mechanical integrity of a machine… This should be implemented asap!!! In every step/combination, all other relevant configuration defines are shown for clarity. 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). Work offsets. 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). MathJax reference. beta_limit_enable false # set to true to enable Y min and max limit switches To test, I have pressed one of the endstops with a finger and have moved the connected axis (in both directions) without the endstop stopping movement. In Pronterface I couldn’t find a stop machine from killing itself button. 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). After powering up a 3D printer the printer’s controller board does not know at which position its axes are. The console got the commands and and it looks like it should have moved. UPDATE: HURRAY !!! My X and Z endstops work Perfectly. I have this switch plugged into first header column for X-min. Software end-stops are enabled by default. alpha_max 200 # this gets loaded after homing when home_to_max is set this is 3d printer hardware protection basics. @arhi: what I want ? site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. Endstops on X and Z axis seem to be working correctly but Yaxis endstop seems to have no effect. I'm frustrated. 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 ). youtube . Asking for help, clarification, or responding to other answers. Have you implemented the functionality you referred to earlier in this tread? alpha_max_endstop nc # NOTE set to nc if this is not installed 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?! Could the US military legally refuse to follow a legal, but unethical order? There is no mechanical failure with the switches, I've tested it with a continuity tester. Connecting Sain Smart Mechanical End Stops to Ramps 1.4? EDIT: I would like to have them separate for auto level but I may try to join them on the same driver. The way this is done is by homing the machine so it knows where it is. My config can be found here: pastebin.com / zJZ4SLBx, endstops_enable true # the endstop module is enabled by default and can be disabled here can you help me… i suppose is in marlin but i can’t find the problem. I don’t know anything about carbide motion but if it’s grbl compatible, it probably won’t work for Marlin. Printer moves korrekt, but even software endstops won't work. Documentation has been updated since the end of February !! Don’t go beyond the maximum limit. 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 feel that the machine has a nebulous idea of where the machine is at. In reading posts on the forum about endstops, it looks like endstops on Smoothie may not work the way I expect them too. I’m using a Ramps 1.4 board with the Marlin-MPCNC_Ramps_T8_16T_LCD_32step_DualEndstop firmware. Yes, this is not supported. They are not configured just like the smoothie wiki because they are NO when plugged in… That’s when I add the “!” invert and M119. Because this is a MKS board and not a community-supported board, you want to contact your seller before trying to get help from the community. on the axis’. 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. I am using a regular limit switch with NC going to the signal pin and the other to ground. 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! ) » is incorrect. Is the line uncommented ? This is functionally identical to “hitting the actual endstop stops the axis”. I have endstops that I bought from makerbot because they have “protection” and let me know when they are triggered. What would you expect on a mill or a fdm printer to do for a move that goes outside of the workspace? "it is possible that the endstop pin on the Atmel chip is not working anymore. That means the z endstop pin doesnt work. I've tried changing home position. Is this true? Also check for continuity again, using a multimeter. (though I really want it to work on my i3 prusa homemade clone). it will only lead people to feel fooled once those kind of troubles are discovered. 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. Here is the boilerplate: Download Marlin bugfix-2.0.x to test with the latest code. If I enable the 3 “limit switches” lines, the printer does stop when the switch is hit, but then I have to reset. 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 ? tailgunner30uktailgunner30uk 12 Aug 2014, 12:50 1.1.7 debug HAS_TRINAMIC_CONFIG ... sdcard HAS_SPI_FLASH SDSUPPORT MARLIN_DEV_MODE M993-M994 - SD / SPI Flash. The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). Any suggestions, advice, or input would be welcome. @Ulysse31 I’m confused about what you are trying to achieve and would really like to understand the rationale behind your request?! 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. 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. Are you using the latest firmware ? Solved Or if I click the move motor buttons pronterface will move it to whatever I want regardless of a switch. Thanks! 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. I have searched and read lots of posts but nothing fixed the issue. I’ll download the latest edge firmware and configure the soft endstops as documented ^^ !! Use MathJax to format equations. beta_min 0 # 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. Apparently it is a bug for MAC but i am using WIndows 8.1. Hello all. 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. Im finally getting around to setting up my Mini Kossel. alpha_min 0 # this gets loaded after homing when home_to_min is set If you want to control Marlin from a tablet, run octopi on a raspberry pi. So to make it clear: Smoothieware does not support software endstops aka. 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 … with mechanical or optical end-stops) is mandatory while building printers. 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 ! Bonjour à tous, Also, the buttons are not responding to clicks and turning the main knob does not work either. I found the way the limit switches are implemented (machine full stop) to be overly dramatic for my use case. 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. I wanted to get a status on the progress in the area of the endstop functionality. Moving the origin in your CAM program is the easiest fix. The endstop did not stop any movement in any direction. Thanks a lot. If the seller is unable to help you, feel free to ask again here. All primary/basic features are already handled by 8bit arch 3d printer controllers, I was search for some new features and enhancements (SD card config, network, speed …), but not in sacrifice of primary/basics ones. com / watch?v=r8IndlYyA_0 (remove spaces). Make sure your job has a work offset if you use 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 may understand that software endstop are not yet implemented, BUT, AT LEAST, is it possible to have hardware endstops working correctly ? 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 ). beta_max_endstop 1.27^ # You can connect two motors to a single driver, that’s no problem, it’s how most people do it on i3-type machines. Printer area. On solidoodles board the + and - are reversed for the endstop connectors by default. gamma_min_endstop 1.28^ # Im having an issue after flashing my Rambo 1.4 to Marlin 1.1.9 with dual endstops and LCD support. How do others use this correctly? As supplied, the endstops are only configured as home switches, in effect, once triggered, you can manually step, or drive the head past them.
