[gizmo333]

Greetings from Slovenia!


First i woud like to apologize in advance for my bad english skills:)!


okay here is my problem, i attached the drawing of myne cnc part that i would like to mill. Everything turns out ok , except the thre holes (10mm) they go out off cennter (i would like to have the distance on both sides 0.91mm , but mach3 shifted the holes to the left so the distance is not equal on both sides) now i would like to know what i"m doing wrong ? Is maybe something wrong with my post processor? if so, would be some on so nice and send me a post processor for solidcam for mach3. any ideas are welcome , please help i'm losing my mind

The type of the machine tha im using is a chinese miling machine 6040


best regards
