Hi, I'm new to Mach3, but I've done GCode before. I'm having trouble with using G81 to drill many holes on my rotary axis. It drills the first hole correct, but while moving to the next hole position, it travels too far. This happens offline too. The example below drills a hole at A356, then goes to A358.14 and increases from there. X axis starts to very slowly move as well. Strange!
G0 X0.3
G0 A356
G81 R0.25 X-0.5
A358
A0
A4
G80
G0 A0
If I replace the G81 with G0 A358 G1 X-0.5, it will stop exactly on 358.
What am I doing wrong?
