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. Thanks a lot. 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. 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. Below is a link to a video I shot testing all of the axis’ against one of the endstops. Configuring Marlin is very simple, so there is not much magic to get sensorless homing to work. I just set up a MKS SBase 1.2 I have everything figured except for two things. 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 feel that the machine has a nebulous idea of where the machine is at. Bed Leveling. I finally said screw it, if I break it I break it! alpha_homing_direction home_to_min # or set to home_to_max and set alpha_max When I home (in Pronterface Here) in the Y direction its as if the endstop is not even connected no response form the switch. Glad to hear that things are moving along. Thanks for contributing an answer to 3D Printing Stack Exchange! Is the line uncommented ? » is incorrect. These are mechanical Makerbot 1.2 endstop switches. 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. In the meantime, if your machine is capable of harming itself, please install min and max endstops and enable limit_switches. EDIT: beta_min_endstop nc # 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 ! 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. @arhi: what I want ? It might, but the motion feedback in grbl is totally different. PS: @Dytoractor : did you found a way to avoid this ? 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. Or I can enable limit switches which pause the machine… sure it paused which is good but the machine is useless at this point until I turn everything off and back on. How to calculate charge analysis for a molecule, Don't understand the current direction in a flyback diode circuit. 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 just set up a MKS SBase 1.2 I have everything figured except for two things. What would you expect on a mill or a fdm printer to do for a move that goes outside of the workspace? the y axis works perfect. Printer area. Software end-stops are enabled by default. I did end up disconnecting which stopped the motors but when I reconnected it started up anew. 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). Marlin has support for four temperature sensors (three extruders, one heated bed). 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 ? 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. 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! ) If I would have homed the Z axis instead of clicking it many times it would have stopped my machine? load or back up SPI Flash and SD. try uncommenting the following lines to enable endstop detection on all pins for troubleshooting. Is this true? I have a couple of questions though. 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. 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. Connecting Sain Smart Mechanical End Stops to Ramps 1.4? I am using a regular limit switch with NC going to the signal pin and the other to ground. 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. 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. Have you implemented the functionality you referred to earlier in this tread? Here we can tell the firmware what the limits are of the travel zones. updated the mks firmware bin to smoothiewares edge. The hard endstop result in a halt state yes, which then requires M999 to get out of. If you configure them as limit switches then you cannot step past them once triggered. Asking for help, clarification, or responding to other answers. If I am wrong then the machine tries to make it to 200mm by brute force! This was without ANY USB plugged in and using the touch screen to move. Depending of the firmware version of your Marlin, in some cases it gives issues, but if you connect to ZMin it will work perfectly. a logical comparison agains a stored min and max value (set on homing) which prevents the machine over- and under-running its axis dimensions? As expected things go wrong. I home it and it finds a corner… then in the config file I say it is 200mm from the home position. with mechanical or optical end-stops) is mandatory while building printers. control M121 - Disable Endstops. 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. The console got the commands and and it looks like it should have moved. 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. Any suggestions, advice, or input would be welcome. Apparently it is a bug for MAC but i am using WIndows 8.1. So from this conversation, I am understanding that only Homing works? 3D Printing Stack Exchange is a question and answer site for 3D printing enthusiasts. The endstop did not stop any movement in any direction. 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. Having my beta-endstop at the max position of my Y-axis I would love to see the bed moving to its logical origin. Testing repeatability of the probe. youtube . To test, I have pressed one of the endstops with a finger and have … Then the machine is able to ignore moves that would go out of the machine area. Here is the boilerplate: Download Marlin bugfix-2.0.x to test with the latest code. alpha_max_endstop nc # NOTE set to nc if this is not installed 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 ). beta_max_endstop 1.27^ # ", This, is clearly too drastic, so useless in my case …. Plugging them in in the max endstops does show change when they are pressed with M119. If they are optical endstops, first make sure that you have S1 in the M574 command. gamma_min_endstop 1.28^ # fly wheels)? I wanted to get a status on the progress in the area of the endstop functionality. If I disable the 3 “limit switches” lines, it goes back to not stopping when the switch is hit. I have everything assembled and wired up. bon courage, has there been a solution to this i have same problem You either run grbl or Marlin, not both. There is no mechanical failure with the switches, I've tested it with a continuity tester. You can set the value of the parameter to 0 (not used), 1 (RRW thermistor 100K) or -1 (RRW thermo couple). 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). I want to insist that « hardware endstops only work for homing action, or as a kill switch. 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. In Pronterface I couldn’t find a stop machine from killing itself button. You can have “hitting end of axes causes the movement to be ignored”, which is what you asked for ( correct me if I misunderstood ). 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. gamma_min 0 # 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). Disable endstops and keep them enabled when not homing. site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. 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. #corexy_homing false # set to true if homing on a hbit or corexy 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. I currently don’t have the LCD, could this be preventing it from working? The travel distance is not calibrated yet and the practical distance will be different than the calculated distance. (though I really want it to work on my i3 prusa homemade clone). 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 ). To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Marlin has the dual endstops. @Ulysse31 I’m confused about what you are trying to achieve and would really like to understand the rationale behind your request?! beta_limit_enable false # set to true to enable Y min and max limit switches If the filament runs out, Marlin will run the specified G-code script (by default M600). alpha_min 0 # this gets loaded after homing when home_to_min is set hi i … I've attached a copy of my Marlin configuration.h file. calibration TOUCH_SCREEN_CALIBRATION Make sure your job has a work offset if you use the endstops. How can a non-US resident best follow US politics in a balanced well reported manner? 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 … Making statements based on opinion; back them up with references or personal experience. #define min_software_endstops true. I have endstops that I bought from makerbot because they have “protection” and let me know when they are triggered. alpha_min_endstop 1.24^ # add a ! com / watch?v=r8IndlYyA_0 (remove spaces). Solved Thanks to #7470, #define ENDSTOPS_ALWAYS_ON_DEFAULT is always uncommented (enabled). *** For other boards you may need to define FIL_RUNOUT_PIN. 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. 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. Are you using the latest firmware ? Could the US military legally refuse to follow a legal, but unethical order? If you don’t find them to be don’t hesitate to ask further questions. #define min_software_endstops false #define max_software_endstops false. 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. Thanks! Endstops are used only for homing, and for limit switches, at the moment. beta_min 0 # If you want to control Marlin from a tablet, run octopi on a raspberry pi. It takes the guess-work out of getting a good first layer and good bed adhesion. -Not very good for a kill switch really. So to make it clear: Smoothieware does not support software endstops aka. Also check for continuity again, using a multimeter. UPDATE: HURRAY !!! After powering up a 3D printer the printer’s controller board does not know at which position its axes are. 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. 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. 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. My endstop configuration is currently: I have X-min enabled and inverted. The thing is : it’s much more difficult to implement than it seems ( or it’d be in already ). Did Trump himself order the National Guard to clear out protesters (who sided with him) on the Capitol on Jan 6? All the motors work correctly, I am just having issues getting the endstops to work. May be there is an explanation for this behaviour, I would be glad to know it, could someone explain that ? can you help me… i suppose is in marlin but i can’t find the problem. 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. 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. Obviously there are many people with problems using TMC2209 with sensorless homing. this is 3d printer hardware protection basics. Work offsets. A typical part has the gcode built with the origin at the parts corner. 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?! 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. The other question I have is how to use the E1 driver to drive my second Z motor on my Prusa i3. As supplied, the endstops are only configured as home switches, in effect, once triggered, you can manually step, or drive the head past them. Does that answer your question, or was there more to it ? I'm frustrated. I am using a regular limit switch with NC going to the signal pin and the other to ground. How to find out if a preprint has been already published, Piano notation for student unable to access written and spoken language. 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 ). 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. Don’t go beyond the maximum limit. 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. All of my attempts to contact any support have ended up with nonsensical responses in broken English that did not address the issue I am having. Endstops on X and Z axis seem to be working correctly but Yaxis endstop seems to have no effect. Moving the origin in your CAM program is the easiest fix. It’s something that is being actively worked on. 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. Please can someone confirm : to resume, on smoothieware, hardware endstops only work for homing action, or as a kill switch. BUt Y does not . beta_homing_direction home_to_max # Printer moves korrekt, but even software endstops won't work. A second issue I have, is that after homing (which works fine) the config flag “move_to_origin_after_home” is ignored / not executed. The unused extruder driver/s are used for the extra stepper/s. 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. 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. I finally got my MPCNC built after several months of start-and-stop work, and it made a pretty respectable crown test drawing!. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. The post copied below says the end stops only work for homing. This issue cannot be closed. 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. 1.1.7 debug HAS_TRINAMIC_CONFIG ... sdcard HAS_SPI_FLASH SDSUPPORT MARLIN_DEV_MODE M993-M994 - SD / SPI Flash. I’m using a Ramps 1.4 board with the Marlin-MPCNC_Ramps_T8_16T_LCD_32step_DualEndstop firmware. Implemented in many other firmware like marlin or teacup …. I've checked M119 and all three of the endstops show to be triggered when manually pushed. 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. Bonjour à tous, I've tried changing home position.
