Im totally new to the world of CNC machines, always wanted one, always too cheap, found the MPCNC… ya know it
Now I basically have the machine mostly ready, the frame is set up, axis are moving nicely, etc… but Im really struggling to set up a homing position however. My plan was to use the Arduino Uno and a CNC Shield V3, which generally works great so far.
Looking from the front at the machine, I want it to home top left, so that should be X- and Y+ right?
Thats how I connected the limit switches I want to use for homing, I dont care about endstops really.
I went an edited the GRBL config.h to exclude Z homing because I later want to use a Z probe, and also set the homing position to $23=1, according to the GRBL docs.
I also disabled Hard limits in GRBL with $21=0.
Now the Axis themself move into the right direction, I think, X+ moves to the right, X- moves to the left, Y+ moves to the back, Y- moves to the front when I stand infront the machine.
But when I hit the home button in CNCJS it moves into the very other directions looking for a homing/limit switch…
At this point Im kinda lost and have no idea what I missed in the configuration…
I hope someone can help me here
thank you and stay safe everyone
