This sounds familiar, can you check the the countermode is indeed set true?
I think pncconf sets the counter mode it two places so you think you have
counter mode set true but its not...

[Emc-users] Another 5i25-7i76 question - spindle encoder this time.
My 7i76 mill is working very well. The last setup before I put everything in its place is to get Andy Pugh's automatic spindle software gearing to work. I have a spindle encoder, that is not-differential, and does not have an index. 16 pulses per rev. I have it wired such that the 3 jumpers (W4, W5, W6) are in the left hand position (closest to the 25 pin connector), and a wire goes to the ENCA+, TB3, pin 7. This should put it in TTL mode, with the pulse train going to ENCA+. Between pin 7 and pin 1 (gnd) when spinning the spindle manually, I get between 0.8v and 5.65v on my digital voltmeter. Input power, 7i76 manual, page 49, says Input Common Mode Range -7 to +12 volts. Input TTL threshold is 1.4 to 1.8v. I HAVE NOT connected (or jumpered) any other input wires for this encoder - they are left floating. The encoder.00.counter-mode is set to 1 encoder.00.filter set to 1 encoder.00.index-invert set to 0, index-mask-invert to 0, latch-enable to 0 encoder.00.scale set to 16 I see nothing - no counts, no "action" on the input. I also don't have much luck googling this stuff - maybe I need to practice more. Does the above look reasonable? Should I jumper the ENCB, IDX, lines somewhere? Yours confusingly, John A.

Re: [Emc-users] Spindle Synchronized Motion Problem
I think this thread has grown in scope. I did use Halscope to look at the signals as suggested by Chris Radek and it showed a discontinuity in the encoder velocity. This led me to looking at the regularity of the index pulse which was found to be flawed. I didn't take any pictures of the Halscope measurements so I assume the post you saw was from another user's problem. In any case, I can't expect the tapping cycle to be reliable if the signals from my encoder are not being accurately relayed to the computer. I'll focus on getting that right before I look any further into LinuxCNC configuration.
