I’m using the SKR 1.4 with DRV drivers and dual endstops for auto squaring. I test every stop using M119 commands and all stops passed the test, yet when I home X, Y or both, 1 endstop from each pair fails to function and their respective stepper will crash that end. Obviously the endstops are correctly configured, compiled, uploaded and wires all connected properly as the M119 tests all prove functional, yet when I home either X or Y, the problem occurs.
I can’t remember where I found the firmware, but it’s original name was “-MPCNC-with-SKR-1.4-Turbo-2209-TMC-Stepper-DualEndstop-master.zip”. I modified it to account for my machine and hardware, was happy that it compiled without any Extruders = 0 issues, but I can’t get over this hurdle.
Any clue what I should look for? Here’s my config files after I updated for my machine.
