Post's switchoffset vs Set variable switchoffset Operation

I’m totally new to Sheetcam and have just finished building a plasma table using candcnc electronics.

The Bladerunner manual says to edit the post we use, in my case the “plasma MP1000-THC post processor with engraver”

I’ve edited switchOffset to = the distance it requires to raise Z so that the torch is just clear of the table by a paper width.

What is the difference between editing the post file’s “switchoffset” value and inserting a Post Variable Operation at the top of Operations for switchOffset?

I imagine it must be one or the other, but not both?

Thanks, Jim

Setting the value in the post provides a default. If you do not set it using post variable the value set in the post will be used. Generally I would recommend setting the post variable while setting up and calibrating then copying that value to the post once everything is working properly.

Thanks Les.
