switch offset problem

Dear Sir ,

I want to ask , must I change for each sheet my switch offset amount in sheetcam or it is same for every sheet on cnc table.

Please note thin sheet has more bending and go down more when torch homing process hit it.

I dont know what i Must do /

Normally you would set the switch offset to a fixed value. It is difficult to allow for the metal flexing because that depneds on where you touch off. If you are directly over the support grid the work won’t deflect at all.

If deflection is a problem the only reliable solution is to reduce the force needed to activate the switch. If your torch/torch mount is heavy you may need to use a spring to take some of the weight.

could a THC help?
