VMC related HAL questions.

When M19 is active there is no speed command, it just enables the spindle so the rotation is just the drive drifting slowly.

So how do I specify orient tolerance?
Added a screenshot of hal config. M3 s60 is active.

The speed command should come from the position PID.

Do you see any output from the PID (if not, have you tuned it?, are the gains being read in from the INI correctly?)
When you say there is no speed command, where are you looking?

So how do I specify orient tolerance?

Code:

setp orient.0.tolerance (number)

Yes, just like that. In degrees.

I'm not looking at any pins, the fact that I can stop the spindle with a light touch tells me that there probably is no speed output.

The screenshot shows a pid.0.output of 325.1263.
Now that I think of it, the pid might might work correctly. If the speed command the pid.0 gets is wrong. The x6 speed problem I still have.

Is it line 11 I should edit? To this?
Can I write the tolerance like this? And then add this line to the ini.

Are you talking about position mode or velocity mode here?

The screenshot shows a pid.0.output of 325.1263.

But orient mode should be using pid.1. You need to see what that one is doing to get orient to work.

Is it line 11 I should edit?

Code:

net spindle-vel-cmd motion.spindle-speed-out pid.0.command

To this?

Code:

net spindle-vel-cmd motion.spindle-speed-out-rps pid.0.command

Can I write the tolerance like this?

Code:

setp orient.0.tolerance [SPINDLE]ORIENT_TOLERANCE

And then add this line to the ini.

Code:

ORIENT_TOLERANCE = (number)

Yes to all the above.

1. position
2. velocity (M3 S60)

I don't know when I can try anything on the machine next time, probably next weekend though

Sorry not to have been more help. I really don't understand why this is being so difficult.
