CNC is new to me am attempting to learn and use.
Have Bobcad V24, have tried several posts all start with Mach3.
Running a Taig DLS 3k.
Can jog (DRO) and examples all control to correct size ie 1"= 1"
create a part in Bobcad post it and it is off by almost a factor of 10 0.1"=1" +/-
and after loading & closing file - jogging with DRO is now off by same factor
G codes seem fine.
Where should I start looking???
