How does the controller find Z Zero? I am using feeler gauges to level the bed and I am wondering how thin is too thin? If I use a .0015 gauge to level the bed does this create an issue with the extrusion on the brim and first layers?
It would be helpful general knowledge to know how the machine records its set positions from home (0,0,0) and if this is pre-programmed into the machine or if it is recorded during the bed leveling procedure.
Thanks,
