Hi Ilya,

That is a Kerf Compensation Error. G41 / G41 are Kerf commands for your controller. Usually these occur when you are asking too much of the compensation and it is unable to calculate the offset for you. There are a couple of things you can try.

1. Review the code and find out where Line 8 occurs on your drawing (use FastPLOT for this) This will let you know where the error is occurring.

2. Determine if you need to redraw that section, or if you are asking too much of the machine, such as cutting a 2 mm wide slot when your plasma has a 3 mm kerf.

3. Either Redraw the area, remove it, or generally fix the problem. Here is a handy guide on closing part closure:

4. If all the above fails, you can try and use FastCAM's Kerf compensation:

Be aware though, by using this, you may be continuing the problem, but just negating it by using FastCAM's Kerf Compensation. Also it means you need to know the Kerf and the program's output will be specific to that Kerf Value.

Hope this helps!

Cheers,

Alex
