Re: EMC2 Screw Cutting Problem

Hi Steve.
I've tried my best to provide you with some meaningful answers to
your questions - (see below) - I hope it helps you to help me.

Thanks for your help, Martin.

ANSWER
I'm looking at SIGNALS spindle-index and spindle-phase-A. Both give a
clean trace on the 'scope.

ANSWER
It is - both index and phase-A

ANSWER
I can't see any output on encoder.0.phase-Z.

ANSWER
encoder.0.phase-Z = no trace on 'scope.
encoder.0.index-enable = no trace on 'scope
encoder.0.position = no trace on 'scope but numeric counter
increments with spindle rotation at bottom of the screen.

ANSWER
Will do

ANSWER
At this stage only the examples included with the software
(threading.ngc and G76.ngc).
