And sorting this for the differences in pin/signal names between the above non-hostmot2 examples, and the hostmot2 names is left as an exercise for the reader. hostmot2 doesn't have a position-scale pin, just scale for instance. setp to 240 as thats the encoder edges for on full turn. I have the index-pulse like this:
####################################################### # for g33.1, motion.spindle-revs needs to be hooked to # encoder.0.position output net gee33dot1 <= hm2_[HOSTMOT2](BOARD).0.encoder.00.position => motion.spindle-revs # and index-enable needs to be enabled setp hm2_[HOSTMOT2](BOARD).0.encoder.00.index-enable true # and then hooked up bidirectional to motion.spindle-index-enable net spindle-index hm2_[HOSTMOT2](BOARD).0.encoder.00.index-enable <=> motion.spindle-index-enable #is false forever but position is incrementing forever if fwd, decrementing forever in reverse. So it appears the Index is being ignored if what I read about how this works is true. > (suitably modified for hm2) What I've tried to do is essentially duplicate The Little Monsters settings, which do work, but one is on a 5i25, the other on a 7i90. The changes in naming of the two makes direct comparisons difficult to translate error free. Same with the 3 axis G0704, which can do rigid tapping just fine, running the g33.1 canned cycle in a loop for peck mode, advancing a fixed amount per peck, usually around half a turn. But again, thats a 5i25 interfaced machine. To switch it to a 5i25 driving a 7i90 is tempting as I am out of i/o and can't add a 4th axis to it that it badly needs. And I am out of room in that monster box for a 7i90 and its breakout boards, I'd have to make/buy yet another box to contain all that. One project at a time please...
