Hi, Just finished putting together a CNC drilling machine and have now stumbled on a problem that I never anticipated....The drilling machine appears to be more accurate than the printer used for the PCB artwork....Tried both a HP2420 (laser) and Epson 2200 (Inkjet) and the results were similar. Is this a known issue with CNC setups?
