So I’m hoping someone here might have some ideas. First issue I am having is that while GRBL does the homing just fine, it always sets the coordinates to -289,-289,1. It is backing off one mm after homing so the real X and Y are -290,-290, instead of 0,0. Any idea why this is happening, and how to fix it?
I upgraded GRBL to 0.9j to get the fix for M30 hanging on the end of a program. Now I am afraid anything try to do a G28 without me having manually changed the G28 offset, is going to crash into the ends of the machine as it tries to get to 0,0,0.
Next is a question. I am trying to run mutliple programs with the same work coordinates. It seems that after chilipepper runs the program it looses the offsets. It appears that the offsets are being set with G92, which I hear is deprecated. Any ideas? I’m setting the bit on the edges and finding the point where it just touches the side of the workpiece, and then doing a G92X-3.175 or G92Y-3.175 to set the axis (the bit is 6.35mm, 1/4").
the buttons set Gxx zero, go to mch zero, set Mch zero, and home mch all dont respond to my click. comes back with “error: unsupported command”.
My code was in inches, chillipeppr was in mm, and a 4"x4"x.25" deep carve sent the spindle to the far corner and tried to plunged the collet into the waste board. now chillipeppr is in inches, and i’m afraid its going to try to send the spindle to across the street.
anybody know what might fix this issue??
not trying to hijack the thread, felt like this was a place i could hopefully find a quick answer
