Touching off

The original post sounds like there might be a tool-length in the tool table, but he is touching-ff without a tool + g43 in effect.

I had a similar problem once and it turned out that I had a length value in the tool table that I didn't know was there. I think it got there by me clicking on Tool Touch Off rather than Touch Off. I cleared all length values from the tool table and it solved the problem.

Thanks, looking through this and the suggestions I went back into CAM and found that my origin was on the bottom left corner of the workpiece not the top. With the origin on the bottom I believe I touch off with a .5 offset whereas if the origin was on the bottom I'd touch off to the top of the workpiece with a 0.0 offset.

in Vectric, edit the post-processor and change the Z variables:

VAR Z_POSITION = [Z|C|Z|1.3|-1.0]
VAR Z_HOME_POSITION = [ZH|A|Z|1.3|-1.0]
VAR SAFE_Z_HEIGHT = [SAFEZ|A|Z|1.3|-1.0]

now works like expected...
