Give this a try. It turns on THC 10mm after the cut starts to allow the arc to stabilize then turns off THC 5mm before the leadout.
The work is done by the two code snippets (THC on and THC off) and the default rule set (Tools->Cutting rules)
I am not sure if this will work because the code snippets are output with a space before the number which is not technically correct. I am hoping your control will ignore the space.

OK, let's try again. Here is the updated job file.

Hi guys,
using the Sheetcam I figured that when it cuts some dull angles of the workpiece, it does something like a cut routine by making a small circle. The problem is that this small circle is so small that meshes up the voltage control and makes the torch diving and colliding on the workpiece.
Any ideas how to get reed of it or change its parameters?
Thanks in advance

I checked it and I have it in "none". The problem is that it does it usually on corners of more than ~120deg and except from the fact that the torch collides because of the small hole that meshes up the arc height control, the circular loop is always on the opposite direction (the torch inserts in to the workpiece).
Is it possible this mesh to be created because of the transition of a cad file to a dxf file with just straight lines and arcs (however the drawing in sheet cam even in very high zoom in it seems OK)? and is it possible by checking the code line by line to see the comands that make the torch to loop in the opposite direction?

I checked with the simulation tool of sheetcam and it seems OK.
I also checked the code line by line and especially at the points where the problem appears, and it seems to me just fine.
I figured out that the problem appears in corners where the torch does a small arc path in order to cut properly. It seems that my machine doesn't read properly the end of the arc and it does one or two circles (with the specified arc center) and then it continoues to the straight line. This seems to happen only on angles >90deg. With angles =90deg it doesnot appear and also with angles<90deg.
Any more thoughts?
