Hey guys: So, I just installed limit switches on my C-Beam machine. Using GRBL Panel, I'm having trouble getting things set up. There's not much info in the GRBL Panel wiki on this. What is the "Current Machine Position" box above the main position indicators? How do I zero this? Seems like every time I do a home function, it sets some or all of the position boxes to these values. Also, the smaller numbers under the main position indicators seem to just display random numbers, related to the "CMP" box above. Cant figure out how to zero these out. Some operations seem to reload these values into the main position boxes - again, does not seem to be any rhyme nor reason to it. Mebbe it's just me... Also, If I do a home, then do a z axis zero, then do home again, it changes my z axis position value. Is this supposed to happen? What is the correct procedure for doing a z axis zero using a probe command? Also, what is the proper procedure for setting the offsets in the offset window? Seems like every time I change them, they just get changed by the program to some other value. The explanation for all these in the WIKI is really dismal.
