I have asked this over at Github and no answers, I have read everything and watched all of the videos and I still have a question. Bcnc appears to automate the probe function. In the wiki manual, it skips right over the Probe tab, and goes to Autolevel, which at this time, I don't need. See pix for the blank spaces that are there to help you get the z 0 set quickly. I have the plate, thickness 1.61 mm and wired in to the controller board. When I place the bit over the plate a few mm it lowers, touches and stops. Obviously, this isn't really z0, where do I tell the software that the plate thickness needs to be subtracted or added depending on your point of reference? Thanks for any help.
