Hi,

The other day I was cutting some DB9 holes in a box. The first two went fine and then the third went crazy.

It started on the straight cutting away but when it came to the corner, it kepts going straight and then started doing some squigles.

So I lifted the head off the job, reset the Z axis and restarted the job.

It was like watching a little kid with a crayon. Zipping around randomly. You could see it on the cutting screen in mach3. Weird.

I thought it might of been because of the lastest version, so I went back to the locked down version of Mach3. Still doing the same.

So that night I tried it on a mates machine. The gantry nealy flew off the end of the router. No where near where the DB9 hole was surpose to be.

Any idea's guys? It might be worth looking into as it looks like an issue.

Here is the code below.

Cheers

Rodney
