Hi All, can anyone help me with a problem i have with my cnc table, its not true (level) keeps moving. What i have been doing is putting a slave board on the bed and skimming it, its just mdf so i can just screw blocks into it to hold the piece im working on, is there anything out ther that i can link to mach 3 like a probe or somthing that automatically adjusts the hight of the tool to always stay true to the bed ??
Cheers
Brian
