I often see confusion by people in IRC about how to disable and enable endstops so that accidentally sending a home command (G28) doesn’t cause their … Marlin now tracks whether it has been homed with G28 as a safety feature. Normally open means the switch closes the circuit when triggered, and in Marlin this seems to be the default in Configuration.h. This time about Motion Configuration.. Repetier. Secondly, posting your config someplace like derglow says might be helpful for specific advice about endstop behavior while homing. Not sure if you got your issue fixed already. E3D v6, and the 'Orion Module' Piezo probe from precision piezo My bad, sorry. It seems like a deadlock... S1/S2 parameters in G0/G1 does not seem to have an effect in runtime. If you don’t have an endstop installed, it will never trigger it and try to go farther than it can, and various bad things can happen, what I call “crashing” the axis. When SHOW_CUSTOM_BOOTSCREEN is defined Marlin will first show your // custom boot image and then the default Marlin boot image is shown. Now onto the latest GCode as of Marlin 2.0.5 G0-G1: Linear Move I am going to use Pronterface/Printrun host program to connect to my printer and issue terminal commands ().That sounded very hairy, but it is just a simple program with a graphical interface. Only have endstops on the mininum end of my axis. En pins.h he tenido que cambiar la ubicación del conector del endstop "Y" al del endstop "E" (al parecer es un bug de la placa). The only case where ENDSTOP_INTERRUPTS_FEATURE makes sense is if you also set ENDSTOPS_ALWAYS_ON_DEFAULT. In my example at the top I have all my endstops disabled except for the minimum Z endstop because the only one I had hooked up at the time was Z. It’s much more common to have either all three MIN endstops hooked up or none at all. I do not wan to use endstop switches only want to put software limit, and that is it. Making it stop checking for endstops when calibrating should fix this problem but I can't seem to narrow down where that code is. Now I load Marlin 1.02 with my modified delta config. I try to upgrade to a newer version of Marlin, but all the versions I tried don't respond on the endstops. This is going to be a, hopefully, complete tutorial on configuring endstops on 3D printers build on Ramps 1.4 using Marlin firmware.. Hello, I do not want to use endstop swich in my MPCNC. G92 X0 Y0 Z0 – to set a zero point. #define Z_MAX_PIN -1 //19. All boards have and E0 driver (some call it something different), and dual firmware capable boards also have an E1 driver, beyond that most boards have breakout pins for more external drivers. In older versions of Marlin all the boards are defined in pins.h , with a section for each board. Hey guys, I’ve been using my mpcnc for a couple of months now, and absolutely love the things I can do with it. I am having difficulty identifying why my X endstops fail to trigger when homing. I know this is the same title as #12726, however I rather started a new issue for clarity as I made quite a few tests.It is also hard to decide if this is a [BUG] or [FR] for Marlin, however it is certainly [BUG] for me. This is undesirable; I would expect an emergency stop. #define Z_MAX_PIN -1 //19, If you are not using RAMPS you just need to find these same lines under the section for your board. I have mechanical endstops for each axis at the minimum of each axis. Everything on a line after a // is a comment, and shows the original value of the pin so I don’t have to look it up to enable it. #define Z_DIR_PIN 48 #define max_software_endstops false I use optical endstops, active high. I came across this topic while configuring marlin myself. Basically, it doesn’t want to go to -X or -Y. Moreover I would like to use the auto bed leveling feature in the Marlin … Sorry again. It will help you when you have to diagnose the errors on-screen, and it will help you even more, if you use the command sets through octoprint. Change the homing direction for the x axis from -1 to 1. I noticed when the machine hits an endstops Marlin simply skips any gcode operations in the restricted area and simply continues when it returns to the work bed area. Bij het testen van mijn optical endstops loop ik tegen het probleem aan dat het triggeren van de endstop door Marlin niet wordt gesignaleerd. All connected endstops are in TRIGGERED. After this command endstops will be kept disabled when not homing. y_min: TRIGGERED [this endstop is currently connected and bumped to] I use optical endstops, active high. If you're just moving around and hit one, that will do nothing. So I got down to work for Configure BLTouch with BabyStepping in the last Marlin available today and satiate my curiosity.. I don't really think it changes anything here but I'll try to connect missing 3 additional and will confirm results in a moment... EDIT 2: Actually it works correctly when all are connected. If I then move Z to position … If you need support for a machine with no endstops, it will need to be added as an optional feature. I have Ender 3 with SKR Mini E3 v1.2 board, which has separate connectors for Z-endstop switch and BLTouch probe. Invert stepper motor direction. const bool Y_ENDSTOPS_INVERTING = true; I'm having a lot of trouble configuring the end stops on my x axis. Re: Marlin 1.1.8 with BLTouch for i3 Pro B - with T8 Lead Screw Post by JohnDeere630 » Tue Mar 27, 2018 10:41 am I agree with William..also, I once had the 2-pin connector from the BL to the Z-min socket reversed, and it acted similar to what you describe, if memory serves. #define Y_DIR_PIN 61 Seems that only endstop against which the movement is executed is verified and because of pullups on missing endstops in my device it couldnt move after homing. Only have endstops on the mininum end of my axis. Disabling #define ENDSTOPS_ONLY_FOR_HOMING causes that printer wont move after G28. This would not be a problem, but I’ve recently started doing multi-layer carves, and for that it’s best to design each layer as a separate SVG, because for some reason Estlcam doesn’t seem to like bringing separate SVG’s in beside each other. All of the endstop inverting lines are true and my disable max endstops line is commented out. I do not wan to use endstop switches only want to put software limit, and that is it. Invert stepper motor direction. Sign in So for my Z endstop that is wired with a NC switch, I would invert the logic: ©2012-2017 OhmEye, James L. Paul | RSS My homing position for my MPCNC build is X+/Y-. Comment out the line to disable max endstops. There is only way to know if the stepper motor direction is correct and it is to try it. How can i disable the second tap? By default Marlin only checks physical endstops while homing, and homing moves are blocking, so polling the endstops does not affect performance. It can not do becouse I do not have end stop switch. HI I have uploaded marlin firmware and the LCD screen now works but the stepper motors only turn one direction. For RAMPS board type 33, my pins.h looks like this: These are my end stop settings. #define X_MAX_PIN -1 //2, #define Z_MIN_PIN 18 I usually use optical infrared sensors for my printers, but I wanted to try the BLTouch sensors since none had fallen yet by my hands. So i installed marlin firmware so i could use manual mesh leveling and it all worked flawlessly, except at the end of my print my end gcode has my bed come to far forward and makes a horrible sound because motors are pushing bed further then it can go.
