(though I really want it to work on my i3 prusa homemade clone). Solved #define min_software_endstops true. PS: @Dytoractor : did you found a way to avoid this ? it will only lead people to feel fooled once those kind of troubles are discovered. I've checked M119 and all three of the endstops show to be triggered when manually pushed. I home it and it finds a corner… then in the config file I say it is 200mm from the home position. BUt Y does not . Asking for help, clarification, or responding to other answers. Thanks to #7470, #define ENDSTOPS_ALWAYS_ON_DEFAULT is always uncommented (enabled). As expected things go wrong. As supplied, the endstops are only configured as home switches, in effect, once triggered, you can manually step, or drive the head past them. How to calculate charge analysis for a molecule, Don't understand the current direction in a flyback diode circuit. Configuring Marlin is very simple, so there is not much magic to get sensorless homing to work. 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. Have you been able to implement endstops similar to the way they work in Marlin? beta_max_endstop 1.27^ # *** It’s something that is being actively worked on. I take marlin with double endstops and i can move all axes but not Y2 and Z2? So from this conversation, I am understanding that only Homing works? Unfortunately, the method I proposed above does not work. gamma_min_endstop 1.28^ # 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. Im finally getting around to setting up my Mini Kossel. 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. tailgunner30uktailgunner30uk 12 Aug 2014, 12:50 3D Printing Stack Exchange is a question and answer site for 3D printing enthusiasts. 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. 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. try uncommenting the following lines to enable endstop detection on all pins for troubleshooting. That means the z endstop pin doesnt work. My X and Z endstops work Perfectly. I want to insist that « hardware endstops only work for homing action, or as a kill switch. move_to_origin_after_home worked last time I tried it ( and it was with a beta axis homing to max too ). It’s me again, was away for a long time … my projects were on stanby for some problems I had … All the motors work correctly, I am just having issues getting the endstops to work. Marlin has the dual endstops. It turned out to be a combination of those lines being commented out and the end stops were connected to the wrong two pins. Software end-stops are enabled by default. If I enable the 3 “limit switches” lines, the printer does stop when the switch is hit, but then I have to reset. I have this switch plugged into first header column for X-min. If I disable the 3 “limit switches” lines, it goes back to not stopping when the switch is hit. Could the US military legally refuse to follow a legal, but unethical order? fly wheels)? Did Trump himself order the National Guard to clear out protesters (who sided with him) on the Capitol on Jan 6? #corexy_homing false # set to true if homing on a hbit or corexy 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). on the axis’. I've attached a copy of my Marlin configuration.h file. #define min_software_endstops false #define max_software_endstops false. Is the line uncommented ? The other question I have is how to use the E1 driver to drive my second Z motor on my Prusa i3. You either run grbl or Marlin, not both. Hello all. Making statements based on opinion; back them up with references or personal experience. All the motors work correctly, I am just having issues getting the endstops to work. Documentation has been updated since the end of February !! Marlin has support for four temperature sensors (three extruders, one heated bed). 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. alpha_min_endstop 1.24^ # add a ! My config can be found here: pastebin.com / zJZ4SLBx, endstops_enable true # the endstop module is enabled by default and can be disabled here It takes the guess-work out of getting a good first layer and good bed adhesion. I have searched and read lots of posts but nothing fixed the issue. I have searched and read lots of posts but nothing fixed the issue. To learn more, see our tips on writing great answers. 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 … alpha_homing_direction home_to_min # or set to home_to_max and set alpha_max Work offsets. beta_max 200 # He wants the machine to ignore any command that would take it outside the work area, which Smoothie can do. If you where to cut out that part it would result in going negative past your endstops and misalign your machine. I've tried changing home position. That’s just a guess. This is functionally identical to “hitting the actual endstop stops the axis”. "it is possible that the endstop pin on the Atmel chip is not working anymore. 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. 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. In the case that connecting the 2 wires to the Probe connector the sensor not works, try to connect to the ZMin connector. So to make it clear: Smoothieware does not support software endstops aka. 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'm frustrated. gamma_max_endstop nc # hi i … 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. gamma_limit_enable false # set to true to enable Z min and max limit switches. (I do not understand all the terms.) 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. If you configure them as limit switches then you cannot step past them once triggered. You can have “hitting end of axes causes the movement to be ignored”, which is what you asked for ( correct me if I misunderstood ). Also, the buttons are not responding to clicks and turning the main knob does not work either. 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 have endstops that I bought from makerbot because they have “protection” and let me know when they are triggered. It might, but the motion feedback in grbl is totally different. calibration TOUCH_SCREEN_CALIBRATION 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. 1.1.7 debug HAS_TRINAMIC_CONFIG ... sdcard HAS_SPI_FLASH SDSUPPORT MARLIN_DEV_MODE M993-M994 - SD / SPI Flash. If they are optical endstops, first make sure that you have S1 in the M574 command. Negative moves do not work on the X and Y axis with endstops. Endstops are used only for homing, and for limit switches, at the moment. Endstops on X and Z axis seem to be working correctly but Yaxis endstop seems to have no effect. This is great, following what is written on the documentation, it seems to do exactly the expected behaviour I was talking about ! I found the way the limit switches are implemented (machine full stop) to be overly dramatic for my use case. @Ulysse31 I’m confused about what you are trying to achieve and would really like to understand the rationale behind your request?! 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). Does that answer your question, or was there more to it ? I have Jumper on XST and YST. When I home (in Pronterface Here) in the Y direction its as if the endstop is not even connected no response form the switch. If yes, why is it not simply and clearly written like that on the documentations ? 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. Connecting Sain Smart Mechanical End Stops to Ramps 1.4? com / watch?v=r8IndlYyA_0 (remove spaces). The unused extruder driver/s are used for the extra stepper/s. This issue cannot be closed. How to find out if a preprint has been already published, Piano notation for student unable to access written and spoken language. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Really? 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. Disable endstops and keep them enabled when not homing. Thanks for contributing an answer to 3D Printing Stack Exchange! I have a couple of questions though. 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. Marlin’s extruders=0 or remapping of pins is used in the firmware to allow the use of all the control boards drivers. I did end up disconnecting which stopped the motors but when I reconnected it started up anew. gamma_min 0 # » is incorrect. Moving the origin in your CAM program is the easiest fix. 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 currently don’t have the LCD, could this be preventing it from working? Im having an issue after flashing my Rambo 1.4 to Marlin 1.1.9 with dual endstops and LCD support. Connect to your printer from host software such as Cura, Printrun or Repetier Host. 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. Apparently it is a bug for MAC but i am using WIndows 8.1. the y axis works perfect. The endstop did not stop any movement in any direction. 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. http://smoothieware.org/endstops#limit-switches. Issue the command M111 S247 to enable maximum logging. MathJax reference. The thing is : it’s much more difficult to implement than it seems ( or it’d be in already ). youtube . Below is a link to a video I shot testing all of the axis’ against one of the endstops. 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 ). updated the mks firmware bin to smoothiewares edge. If I get this figured out, I am going to buy a board from you guys to put in my k40 laser. 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. Can an exiting US president curtail access to Air Force One from the new president? 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. The console got the commands and and it looks like it should have moved. 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. Enable endstops and keep them enabled when not homing. I would like to have them separate for auto level but I may try to join them on the same driver. I just set up a MKS SBase 1.2 I have everything figured except for two things. If I am wrong then the machine tries to make it to 200mm by brute force! In the meantime, if your machine is capable of harming itself, please install min and max endstops and enable limit_switches. There is a spec here that explains a bit : https://docs.google.com/document/d/1U6nzx1boqF-J2GGPWF4yIaaVib0JNodVWSKBfwiyp_M/edit#. 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?! ... move X/Y/Z to min endstops\nG29 ;auto level"\n. I’m using a Ramps 1.4 board with the Marlin-MPCNC_Ramps_T8_16T_LCD_32step_DualEndstop firmware. 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. Bed Leveling is a standard feature on many 3D printers. These are mechanical Makerbot 1.2 endstop switches. #define max_software_endstops true. You can set the value of the parameter to 0 (not used), 1 (RRW thermistor 100K) or -1 (RRW thermo couple). 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. site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. How far would we have to travel to make all of our familiar constellations unrecognisable? If I would have homed the Z axis instead of clicking it many times it would have stopped my machine? Re: (Kossel) Alpha axis crashes into end stop AFTER successful homing 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.
