Guys,
Out of curiosity, can an EMC lathe make threads without spindle feedback?
On cnczone.com a guy posted pictures on a thread made with Mach without
spindle feedback, only a VFD as speed controller. They looked truly good.
I know there are problems with it (torque figures, exact positioning,

Na, that wasn't my purpose so please let Mach stay out of this. :)
Thanks for the replies, I was interested in the theoretical manner.

Out of curiosity, can an
emc's motion controller uses the following HAL pins during the G33
spindle synchronized move and G76 threading canned cycle:
motion.spindle-revs
motion.spindle-index-enable
These must behave like the canonical encoder interface pins 'position'
and 'index-enable', described here:

Not sure about what was posted as the link is rather generic. Mach3 uses an
index sensor (slotted disc and opto) to get angular orientation and speed.
Could not work with just a VFD as you need to know the angle to start each
pass. But threads are pretty good with the simple opto gate or
