Profile Circle on 3040

Did you zero your Z on the top of the part? You can see in his code:
G0 X0.0 Y0.0
G0 Z1.0
G1 F300.0 Z-0.4
G1 F800.0 X40.0
G1 Y40.0
G1 X0.0

That the Z will move to 1mm above the part and then sets the feed rate to 300mm/min and drops the Z to -0.4mm below the top of the part.

What do you mean by (just hovers) ie does it stay still or does it follow the intended path?

Yes I zeroed the top.

The z seems to move up the further it gets into the job.

This is on some scrap pcb board.
