rigid tapping g33.1 isnt working spindle isnt sync

The exact names are usually different depending on the hardware used to read the encoder. In Axis go to Machine > Show Hal Configuration the look in Pins to see the pin names you actually have.

I did that. I ended up using halmeter like andy said and know that it is working. I could see a change in state when calling for a g33.1. That being said im lost as to why its not working

Is your spindle at speed working?

JT

yes it is.

now im beginning to wonder if the other axis, x, y, z, are getting the index. I cant replicate the same testing method on them due to it creating a joint following error. I tried to invoke the g33.1 and spin the axis by hand but that just throw's the error and shuts the machine down I tried to increase the following error in the ini but to no avail. I cant seem to setp net or unlink anything in the test hal line of hal config. so that I can test the hook up for polarity. I suspect it is correct im using all of the same encoders on everything and used the same diagram for wiring.

when issuing a g33.1 should the sync axis start to move till the index is found or is that all done in the homing sequence? just curious cause none of my axis move when issuing the g33.1 and ive tried all axis to get synced motion.

here is my z axis hal

Can you attach your compete hal file ( you may need to rename its extension to .txt) or include the part that has the HAL spindle wiring?

G33.1 not starting is most likely a spindle issue, either in the HAL wiring or possibly the index polarity
