New Memeber and very new to CNC

Another thing to try is to raise the bit about 10mm above your PCB and set that to zero. Then do a dry run (also known as "cutting air") and make sure the tool path and speed looks as you were expecting. One thing to check is that non cutting moves are a few mm above the PCB, not at zero.

Hi Fred,
Ok sound interesting. So does that mean whatever software you use to run the *.nc file, the coordinates are offset from/to this? Would this be a rule of thumb procedure before each job?

Thanks
