I wanted to get a status on the progress in the area of the endstop functionality. 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. 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 thing is : it’s much more difficult to implement than it seems ( or it’d be in already ). I have Jumper on XST and YST. Does that answer your question, or was there more to it ? Thanks for contributing an answer to 3D Printing Stack Exchange! 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’m using a Ramps 1.4 board with the Marlin-MPCNC_Ramps_T8_16T_LCD_32step_DualEndstop firmware. Testing repeatability of the probe. If you where to cut out that part it would result in going negative past your endstops and misalign your machine. Software end-stops are enabled by default. I have took a look to the limit_enable thing => it is clearly too drastic ! Making statements based on opinion; back them up with references or personal experience. How to find out if a preprint has been already published, Piano notation for student unable to access written and spoken language. 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. Make sure your job has a work offset if you use the endstops. I have everything but two 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! ) I’ve chosen this solution for building my first 32bit printer because of the features it has, BUT, if I knew that from the beginning, I may not have done that choice. The endstop did not stop any movement in any direction. 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. This is great, following what is written on the documentation, it seems to do exactly the expected behaviour I was talking about ! I'm frustrated. Can an exiting US president curtail access to Air Force One from the new president? Are you using the latest firmware ? -Not very good for a kill switch really. Marlin’s extruders=0 or remapping of pins is used in the firmware to allow the use of all the control boards drivers. As expected things go wrong. Enable endstops and keep them enabled when not homing. 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. 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. Im having an issue after flashing my Rambo 1.4 to Marlin 1.1.9 with dual endstops and LCD support. Work offsets. (I do not understand all the terms.) That’s just a guess. 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 ? Any suggestions, advice, or input would be welcome. I don’t know anything about carbide motion but if it’s grbl compatible, it probably won’t work for Marlin. I have searched and read lots of posts but nothing fixed the issue. Issue the command M111 S247 to enable maximum logging. Having my beta-endstop at the max position of my Y-axis I would love to see the bed moving to its logical origin. ", This, is clearly too drastic, so useless in my case …. To test, I have pressed one of the endstops with a finger and have … Could the US military legally refuse to follow a legal, but unethical order? load or back up SPI Flash and SD. No dishonesty there, just a lot of hard volunteer work. The hard endstop result in a halt state yes, which then requires M999 to get out of. Below is a link to a video I shot testing all of the axis’ against one of the endstops. gamma_min_endstop 1.28^ # 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 is possible that the endstop pin on the Atmel chip is not working anymore. Endstops on X and Z axis seem to be working correctly but Yaxis endstop seems to have no effect. When I home (in Pronterface Here) in the Y direction its as if the endstop is not even connected no response form the switch. For other boards you may need to define FIL_RUNOUT_PIN. The post copied below says the end stops only work for homing. #define max_software_endstops true. Documentation has been updated since the end of February !! First atomic-powered transportation in science fiction and the details? I have endstops that I bought from makerbot because they have “protection” and let me know when they are triggered. A second issue I have, is that after homing (which works fine) the config flag “move_to_origin_after_home” is ignored / not executed. alpha_max 200 # this gets loaded after homing when home_to_max is set 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. It takes the guess-work out of getting a good first layer and good bed adhesion. If the filament runs out, Marlin will run the specified G-code script (by default M600). To learn more, see our tips on writing great answers. I want to insist that « hardware endstops only work for homing action, or as a kill switch. So from this conversation, I am understanding that only Homing works? 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. 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. 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. 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 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. How do others use this correctly? If you want to control Marlin from a tablet, run octopi on a raspberry pi. The console got the commands and and it looks like it should have moved. Here we can tell the firmware what the limits are of the travel zones. try uncommenting the following lines to enable endstop detection on all pins for troubleshooting. Thanks! to invert if endstop is NO connected to ground These are mechanical Makerbot 1.2 endstop switches. 1.1.7 debug HAS_TRINAMIC_CONFIG ... sdcard HAS_SPI_FLASH SDSUPPORT MARLIN_DEV_MODE M993-M994 - SD / SPI Flash. BUt Y does not . (though I really want it to work on my i3 prusa homemade clone). After powering up a 3D printer the printer’s controller board does not know at which position its axes are. Or if I click the move motor buttons pronterface will move it to whatever I want regardless of a switch. alpha_min_endstop 1.24^ # add a ! Is this true? gamma_limit_enable false # set to true to enable Z min and max limit switches. 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. Apparently it is a bug for MAC but i am using WIndows 8.1. Have you been able to implement endstops similar to the way they work in Marlin? If I get this figured out, I am going to buy a board from you guys to put in my k40 laser. Then the machine is able to ignore moves that would go out of the machine area. Please can someone confirm : to resume, on smoothieware, hardware endstops only work for homing action, or as a kill switch. I have everything assembled and wired up. What would you expect on a mill or a fdm printer to do for a move that goes outside of the workspace? As supplied, the endstops are only configured as home switches, in effect, once triggered, you can manually step, or drive the head past them. on the axis’. The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). Printer moves korrekt, but even software endstops won't work. All the motors work correctly, I am just having issues getting the endstops to work. My endstop configuration is currently: I have X-min enabled and inverted. 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). Disable endstops and keep them enabled when not homing. A friend sent this board to me, I thought it was going to be a real SmoothieBoard until i took a look at it. Bonjour à tous, 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. 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. PS: @Dytoractor : did you found a way to avoid this ? It’s something that is being actively worked on. If the seller is unable to help you, feel free to ask again here. The endstops are wired NC -> top 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. beta_max 200 # gamma_min 0 # 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. … 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. I have this switch plugged into first header column for X-min. fly wheels)? RAMPS-based boards use SERVO3_PIN. This is sad… and dangerous for the mechanical integrity of a machine… This should be implemented asap!!! In the case that connecting the 2 wires to the Probe connector the sensor not works, try to connect to the ZMin connector. This command can be used to enable one or more steppers (X,Y,Z,E). Have you implemented the functionality you referred to earlier in this tread? 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 ). control M121 - Disable Endstops. He wants the machine to ignore any command that would take it outside the work area, which Smoothie can do. It might, but the motion feedback in grbl is totally different. 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. 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 finally got my MPCNC built after several months of start-and-stop work, and it made a pretty respectable crown test drawing!. this is 3d printer hardware protection basics. If they are optical endstops, first make sure that you have S1 in the M574 command. Endstops are used only for homing, and for limit switches, at the moment. 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). If I am wrong then the machine tries to make it to 200mm by brute force! Could you please explain what I should do ? Is the line uncommented ? *** In the meantime, if your machine is capable of harming itself, please install min and max endstops and enable limit_switches. Depending of the firmware version of your Marlin, in some cases it gives issues, but if you connect to ZMin it will work perfectly. I am using a regular limit switch with NC going to the signal pin and the other to ground. What sort of work environment would require both an electronic engineer and an anthropologist? 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. 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. @Ulysse31 I’m confused about what you are trying to achieve and would really like to understand the rationale behind your request?! Hello all. UPDATE: HURRAY !!! Re: (Kossel) Alpha axis crashes into end stop AFTER successful homing I am having problems with my Y endstops from working . Im using CNCjs and it seems to connect fine but when I go to move it though the GUI it doesn’t move. How can a non-US resident best follow US politics in a balanced well reported manner? 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. 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. Well I’m sorry I do my best to make my answers complete and straight. I have edited the config and tried with and with out the ! ... move X/Y/Z to min endstops\nG29 ;auto level"\n. That means the z endstop pin doesnt work. 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. Yes, this is not supported. How to calculate charge analysis for a molecule, Don't understand the current direction in a flyback diode circuit. 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. Glad to hear that things are moving along. In every step/combination, all other relevant configuration defines are shown for clarity. I've tried changing home position. You can connect two motors to a single driver, that’s no problem, it’s how most people do it on i3-type machines. 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. alpha_max_endstop nc # NOTE set to nc if this is not installed #define min_software_endstops true. If you configure them as limit switches then you cannot step past them once triggered. 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. @arhi: what I want ? 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 … Connect to your printer from host software such as Cura, Printrun or Repetier Host. Marlin has the dual endstops. 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. Im finally getting around to setting up my Mini Kossel. 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 ). Connecting Sain Smart Mechanical End Stops to Ramps 1.4? Also, the buttons are not responding to clicks and turning the main knob does not work either. Locate the lines #define TEMP_SENSOR_N where N = number of the extruder (0-2) or BED for heated bed. I currently don’t have the LCD, could this be preventing it from working? calibration TOUCH_SCREEN_CALIBRATION 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. 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. Are Random Forests good at detecting interaction terms? Really? 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. This was without ANY USB plugged in and using the touch screen to move. Use MathJax to format equations. when you hit an endstop in max, you cannot go any further forwards, but you can still operate and go backwards. There is a spec here that explains a bit : https://docs.google.com/document/d/1U6nzx1boqF-J2GGPWF4yIaaVib0JNodVWSKBfwiyp_M/edit#. updated the mks firmware bin to smoothiewares edge. alpha_min 0 # this gets loaded after homing when home_to_min is set it will only lead people to feel fooled once those kind of troubles are discovered. I just set up a MKS SBase 1.2 I have everything figured except for two things. If you don’t find them to be don’t hesitate to ask further questions. I have tested that my endstops function by sending M119 and verifying that the endstops correctly show OPEN or … I think I had the wrong idea of what an endstop did as well. You can have “hitting end of axes causes the movement to be ignored”, which is what you asked for ( correct me if I misunderstood ). tailgunner30uktailgunner30uk 12 Aug 2014, 12:50 Thanks a lot. You can set the value of the parameter to 0 (not used), 1 (RRW thermistor 100K) or -1 (RRW thermo couple).
