I found out early on you may as well throw out the crooked stuff.... Use
flat stuff to start with and save the hassle. The carriage wheel method
fails when you have a bunch of holes cut here and there from earlier cut
parts.

It's usually the occasional part that "flips up" into the path of the
torch head that affects me. I don't think any THC control can really fix
that anyhow.

When that happens, Just having a control that automatically shuts down
the Torch on a feedhold, and re-lights on restart is the best bet. Pause
the machine, move the part out of the way and restart.

FlashCut has that figured out real well including any Re-Light dwell
time you may need. What they are STILL missing though is a "hardwired"
Feedhold option. (it's coming) You can "get there" by using a USB
programmable device, but I sure would like a dry contact switch on a
simple handswitch for this.
