I’m a starter with grbl an UGS, I’m using a Arduino uno with a cnc shield V3. The first time I’d started UGS and connected the Arduino I could move the x, y, z, axis. Not the right step/mm but I can adjust this. But right after that I went in “Y-alarm”. Now I cannot do anything, resetting the alarm doesn’t do anything. The Y-alarm just pops up right after the reset. I don’t use any limit switches yet.
Someone who knows what to do? I can’t figure it out because I did jog Al the axis ones. I tried unplugging Al the stepper motors and the stepper drivers but the same Y-alarm occurs. I tried rebooting the UGS, the computer, the Arduino. $22=0 and $22=1… Nothing works.
