MGP to set spindle speed

Does anyone know if you can use the MPG so set the spindle speed in manual mode? I want to use the MPG to replicate hitting F11 and F12.

I am trying to build a control panel with the PoKeys USB board. I want to use the MPG to set all of the selectable values:

Jogging (incremental)
Jog speed (continuous)
Feed override
Spindle override
Spindle Speed
Max Velocity

Also, does anyone know if you can have a constant multiple set up for rotary axes? Basically you could use that multiple to set jog speed and max velocity for rotary axes using one value (for linear and rotary axes). It would be some multiple to convert the linear mm/min to rotary deg./min. It would be a compromise of course, but would be handy versus having two more values to set for rotary axes.

How do other controls handle this? Seems like Max Velocity should be a percentage of max feed rate and not a discrete feed rate value. Also strange that EMC2 does not distinguish between max rapid feed rate, and max cutting feed rate.

Thanks

If you use halui to change Max-Velocity then you can scale it to be percentage using a MPG or if developer version a mux and switches.
How is using an mpg handy for overrides? Do you put a physical stop on the the dial so you can only go to 100 percent?
I think I would like a rotary switch with stops much better.

yes having EMC not distinguish between mex rapid and max feed is a little odd - I'm pretty sure it ws just easier to program that way
and in most cases not that big of a deal. I would think more of a problem with a lathe using constant surface speed ....

I know the Haas uses the MPG to set the overrides. I think Milltronics does too. I have used Haas and it is OK. I suppose a dedicated knob would be better. Using the MPG for everything does keep the panel uncluttered though.

Thanks for the input. How do I setup to use a percentage if the max_velocity values are different for all the axes?

Max Velocity covers all axes.
If an individual axis's max velocity is below the Max Velocity setting then It will not be limited.
This is my under standing.
So yes you can scale your fastest axis as a percentage and if the others are significantly slower
They will not be the same percentage.

But I still have to set Max Velocity for both rotary and linear axes. I want to combine them some way.
