				today i got a new problem. at the moment my plasma cutter does a probing with every new cut.
the consequence of this is that when the torch comes to a point where it has already been cut and makes the next cut the torch travels underneath the material during probing because it does not encounter any resistance. because there is no material at this point
how do you solve the problem?

				I think what you’re looking to do is skip the probe if the last probe was within a certain distance of the first probe.  
If so, I think this will help you:
linuxcnc.org/docs/devel/html/plasma/qtplasmac.html#qt_ihs-skip
IHS skip distance is set on the parameters tab in the probing section.
Hope that helps

				If i understand correctly, that is a CAM issue, torch should never probe where there is no material.

				I think you are not totally wrong snowgoer540
@tommylight
The problem is not in the code, there is material. but it press down by the wight of the torch.
so i think i have to use the ihs parameter to disable the probe

				I think i will realise a ohmic probe later. but for the moment. How can i make it that plasmac makes only one probe at start and no more
during the job?
Should i use ihs skip?

				If your material gets pessed down by the torch then it means it must be bending up during cutting so IHS Skip wont help you for that situation. You need stable material to rely on IHS Skip.

				Ok, last question for this problem, how can i say the machine to only one time on start a probing?
And not on every cut in the job.
