There are lots of K40 laser videos on youtube about using air to keep the cut clean.

Mach4 has 2 ways of doing a dwell G4 P100 (0.1 of a second) and also G4 X1. (1 second dwell).

Try changing the P to an X

General Mach Discussion / Re: Circle not circle but oval - no backlash on the axis, steps per unit set OK,...

It may be a good idea to run the same circle with a feed of 100mm/min and see if that makes it round.  This may be a CV issue.

Rotate the laser body 90 degrees and see if the error swaps axis, do not change the focus though so keep it at the same height.

There is nothing wrong with the code, maybe it should have a G90 in it but it will still work without.

My guess is something is loose or slipping on a shaft if your steps are set to the correct values.

Not a single 4th axis move in the program so check your CAM settings.

The Mach3 parser is a bit limited and soon gets confused.

It is not keen on any real numbers in a calculation.

#100=-1 is also a problem.  #100 = [1 * -1] works.

The safest way is to keep the lines simple and always put values into #vars with lots of enclosing square brackets.

I am not sure you can do that if the property is on a panel.
