Which Encoder for Mach4 Lathe Threading?
« on: September 23, 2019, 01:56:49 PM »
Hello,

i want to retrofit my Old Emco Lathe with Mach 4. The Original Spindle Encoder just has an A and B Signal. Can i use it again for threading in Mach4? or will it only works with an A/B/I Signal Encoder?

Kind regards
Andy

Hi,
lathe threading is a realtime function and is therefore enacted by your motion controller, being realtime, under supervision
of Mach4, which is not.

The question is what motion controller are you using and what encoder does it expect?

Hello Craig,

thanky for your reply. The Motion controller is an Pokeys57cnc. Do you know this?

Hi,
I'm not personally familiar with the PoKeys board.

I'm fairly sure that the 57CNC has lathe threading capability. What you need to find out is what the 57CNC expects.
It may be one of:
1) An index signal only, ie one pulse per rev.
2) A single A (or B) channel and an index signal
3) Full house, that is, A&B channels and an index signal.

An email to PoKeys or maybe a search of the PoKeys board on this forum will get you the answer.

Hello Craig,

i ask the pokeys Support and this two Options would be working:
1) An index signal only, ie one pulse per rev.
2) A Encoder Signal and an index Signal#

next the is to get an Encoder With A/B and Index Signal

best whishes
