THC experimental

Finally got the plasma PC upgraded to Linux Mint 17.3 and built the dgarr/external-offsets branch. I've got the thc component almost done just need to sort out how to remove the offset after a cut is finished and I'm ready to test.

I look forward to seeing the results!

I saw some notes about zeroing the offset and on the very last line of
ocs/src/motion/external-offsets.txt

Dewey says
" More complex hal implementations (like eoffset_demo.ini above)
+allow zeroing offsets without requiring a 'Machine-on/Machine-off' toggle."

So the answer is in his ini file somewhere

Thanks, I'll take a look at that in a bit when I get out to the shop. Testing another branch from Dewey on a mock up gantry for per_sec_homing down here in the beer cave

Found it I think. In the same doc file, he says

I think that is so when you power up you don't get an unexpected movement. I need to remove the offset after the cut is done either as the torch moves up (like I did in the current thc component) or at some safe Z height.

I understand, so the tricky bit will be sensing a safe height. Best of luck with it.
