I am having trouble setting up threading on my lathe. At this point I am thinking my spindle encoder is bad. I have the following setup in my HAL File:
net spindle-revs hm2_[HOSTMOT2](BOARD).0.encoder.01.position motion.spindle-revs net spindle-vel-fb scale.0.in motion.spindle-speed-in hm2_[HOSTMOT2](BOARD).0.encoder.01.velocity net spindle-index-enable hm2_[HOSTMOT2](BOARD).0.encoder.01.index-enable motion.spindle-index-enable My Parameters are set as follows: setp hm2_[HOSTMOT2](BOARD).0.encoder.01.counter-mode 1 setp hm2_[HOSTMOT2](BOARD).0.encoder.01.filter 0 setp hm2_[HOSTMOT2](BOARD).0.encoder.01.index-invert 0 setp hm2_[HOSTMOT2](BOARD).0.encoder.01.index-mask 0 setp hm2_[HOSTMOT2](BOARD).0.encoder.01.index-mask-invert 0 setp hm2_[HOSTMOT2](BOARD).0.encoder.01.scale 1024 For everything else, the spindle has been working fine. I have been running in G96 spindle speed mode, the RPM that the encoder reads is perfect. However, when I try and do a thread, the process never starts. The machine goes to the start point and just sits there and waits. I am assuming it is waiting for an index pulse and never receives it. From what I have read in the manuals - when the index pulse is found, the motion.spindle-revs goes to zero during a threading cycle. On my machine this never happens. It just continues to count. I ran my G-code in the lathe sim and it seems to work fine. I am using a mesa 5i20 and a 7i33 daughter board. The encoder is connected to the 7i33 board. The encoder is an automation direct TRD-N1024-RZVWD.
