need help with post processor

[kbenz]

Had to reload sheetcam. DTHCII & DTHC IV post processor with/without Plate marker. is the one I was using before. My z will not origin out to my ohmic sensor now. I have a setting off somewhere but can't figure out what

[acourtjester]

sometimes the Ohmic sensor is tied to the probe input, if you look at your G-code and see a g31 that is what it is tied to a g28 is for Z home.
In the post processor edit look at the OnPinDown section.

Well that is not the same post processor, I would suggest you contacting CandCNC, they have answered question when I used their components, Tom even answers post here, but I sure he is to busy to read everyday, go directly to their site via email or post on their blog.
