PathPilot Lathe with 6 place turret

Thanks Brian!
Do you also have the files needed for the oracchanger?

I got the spinde speed encoder working on my old hal file, I will post the HAL config when I get it working again.
What input signal do you have from your encoder?

Here is the version I'm currently using

How is the convertion going BrianTuck?
My machine is now up and running thanks to your Hal file.
I had to rewrite the Comp file for my turret to get the toolchange to work.

Nice to hear your up and running.

Sorry about the delayed response ,I haven't had time to work on it lately as it's my busy season.

I still need to get the return home on tool change and get the spindle speed hooked up

Brian

Ok ,back to the grindstone.

I fire up the controller and send x and z home and then set g30. I move up to my work-piece set z to zero and x to 1" (the material diameter). When I go into offset's and click touch tool I get a "invalid diameter" error , I've tried -1 for the diameter also. I also notice that the green leds never light up by the x and z dro's.

Thanks' Brian

Oh i see, you have to manually enter the offset and then click touch tool.

Here is the start of getting my spindle speed input. I got a stock martin gear and bored it out to fit my spindle. Then i fabricated a mounting bracket and bearing block to mount encoder.

Brian

What is the proper way to get the high speed encoder input from the 7i76 ? Is this right?

net spindle-phase-A <= hm2_5i25.0.7i76.0.0.input-12
net spindle-phase-B <= hm2_5i25.0.7i76.0.0.input-13
net spindle-phase-Z <= hm2_5i25.0.7i76.0.0.input-11

Thanks'
Brian

No, that gives you access to the encoder input pins,
bypassing the encoder hardware.
To use the high speed counter for the spindle, you use the hardware encoder position pins:

hm2_5i25.0.encoder.00.position

The position number will only be valid if the encoder scale is set, for example:

setp hm2_5i25.0.encoder.00.scale 4096

( that would be appropriate for a 1024 PPR encoder = 4096 quadrature counts per turn )

Thanks' PCW ,
here is the full code to read encoder. The scale was buried in the ini file. The trouble shooting leds never light up.

# note: gpio pins only read at servo thread frequency
# these nodes are only for driving diagnostic "LEDs" in the UI
# this is only going to be useful when the spindle is rotated by hand slowly
