PathPilot Lathe with 6 place turret

Andy,
Yes that brings up the halmeter , If I look at spindle-encoder-count I can turn the spindle and see the count go up and down. If I look at spindle-index-enable it always stays false while I turn the spindle. I know the encoder index works because I checked it with a led.

Thanks' Brian

If you have a high resolution spindle encoder its quite likely you will not be able to detect the index signal with halmeter
One way to test the index is to sets the signal that carries index enable and then monitor that signal as you rotate the spindle by hand:
halcmd sets index-enable true
( index-enable should go true )
slowly rotate the spindle
( index-enable should go false when index is crossed )

Note "index-enable" needs to be replaced with whatever signal name conveys the spindle index enable in your hal file

here is what is in my hal file.


net spindle-index-enable hm2_5i25.0.encoder.00.index-enable <=> motion.spindle-index-enable

so would i type ?

halcmd sets motion.spindle-index-enable true

Thanks' Brian

no,
halcmd sets spindle-index-enable true

Ok that worked, sets it true and it turn to false after turning the spindle a half round or so. When I try and thread the lathe gets right where it wants to start threading and then stops.

It's counting down.

ok, I changed this

setp hm2_5i25.0.encoder.00.counter-mode 0

to this

setp hm2_5i25.0.encoder.00.counter-mode 1

it seems to be working ,but I'm just air cutting

I tried a negative scale and it still counted backwards ,also I did a test cut and it seems to be cutting more threads per inch than it should be (maybe double).

Thanks Brian
