I cannot for the life of me figure out how to incorporate it into the logic. Because I have the velocity-mode signal connected to motion.spindle-on I don't seem to be able to drive hm2_5i25.0.7i77.0.1.spinena with motion.spindle-on (through the spindle-enable signal that is standard).

Maybe use the OR2 HAL component to enable the drove from motion.spindle-on _or_ motion.spindle-orient.

Hey andy - the issue I run into is that both of those pins are already connected to signals. I'm using code from your vmc_toolchanger config:

# this switches modes
net orient-mode 	        motion.spindle-orient orient.0.enable pid.1.enable mux2.0.sel
net velocity-mode	motion.spindle-on pid.s.enable #hm2_5i25.0.7i77.0.1.spinena 
net orient-dir		motion.spindle-orient-mode orient.0.mode

I am interpreting your suggest as this:

net spindle-enable      => hm2_5i25.0.7i77.0.1.spinena

loadrt or2
addf or2.0 servo-thread

net velocity-enable or2.0.in0 motion.spindle-on
net position-enable or2.0.in1 motion.spindle-orient
net spindle-enable or2.0.out

In other news, I have my spindle VFD running in closed-loop vector mode now. I connected the built-in encoder signals from the spindle motor to the VFD to close the loop at the VFD, and I will pass the external encoder signals directly to LinuxCNC.

I'm assuming I should remove the spindle velocity PID component from my hal now?

I've tested the VFD down to 1Hz which is about 33RPM so if Orient-Mode wasn't working because of VFD issues, that won't be the case any longer.

Alright! I finally figured out the logic needed to enable the spindle in both velocity and position modes. Moving the or2 inputs did the trick - seems obvious now but I stared at this code for hours today.

When I run an M19 code I get VERY SLIGHT movement of the spindle (probably less than 1 degree) and the spindle softly resists my attempts to move it by hand.

The issue now may be scaling? John's schematic has different scales for Position vs. Velocity mode - is that necessary?

Also I kept the velocity mode PID for now.

spindle.hal

net spindle-index-enable  <=> pid.s.index-enable

Does the spindle position appear to match the command (have a look at the command and feedback pins of the position PID and see if they appear to be in the same units, and if they agree with what you think they should show.

I think that M19 takes degrees and the HAL pin is revolutions, but I am not sure of this.

I think you are right andy. I sat down and drew up my own schematic last night because trying to sort it all out in my head, at the machine, wasn't working. I spent two days going backwards. Writing it out on paper helped me keep track of the units I'm working in.

My interpretation of the orient documentation is that orient.position and orient.command work in revs but orient.angle is fed degrees. I believe the output of the position PID will be in RPS and will need to be scaled to RPM before entering the Mux2 component (and perhaps a small offset to help with slow speed).

Attached is the schematic I'm hoping to code tonight, feeling pretty good about it. Eliminating the velocity PID made sense because 1) the VFD is running closed loop vector mode and 2) I am reading true spindle speed from an external encoder attached to the spindle, which is attached to the motor at 4:5 ratio.

I am scaling the Aout5 signal by 4:5 at the end of the system which means I lose some speed resolution but I don't think it will make any practical difference.

My spindle is now moving under an M19 command, which is good. It seems now I need to tune the PID. So far I get either zero movement or the spindle overshoots the commanded position by several revolutions.

Under every rock is another hard place it seems :laugh:

One challenge is that as the spindle passes the targeted angle, it thinks it has fulfilled the orient and disables the orient enable/position PID and the spindle then drifts off target.

Maybe debounce the spindle-oriented signal so the spindle has to be in-position for a certain length of time.

The other way might be to require spindle in-position _and_ velocity=0 (or close)

I'm using the edge component from your spindle.hal file. Does edge give me this type of time control?

I can see how adding an ADD test with position and velocity. I haven't seen this discussion come up anywhere, seems like something that would have been solved already

I added an and2 component and used that to force the orientation remain enabled until both the spindle velocity is near zero and the spindle is near commanded angle.

The logic works - so thanks for the suggestion andy. Although it can take 5-10 seconds of searching for the spindle to lock on. I played with the PID gain values a bit but I probably need a more methodical way of tuning than just random guesses/observations.
