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.
