0.0 v with M5
6.4v with M3 S12000

Ok well this is where it gets a little sketchy with this BOB because I'm not quite sure which settings to tweak to fine tune the voltage.

Start by changing the Spindle Pulley Max speed to a higher number then check the voltage and see if it goes down.?
We are looking to get around 5V With S12000 and 10V with S24000.

I'll try and see if I can find out how the speed Ref voltage is handled and changed with this BOB.

Edit:
Ok well after bit of thought it occured to me that the Steps per setting in Motor tuning for spindle could be used as the Carrier frequency and with 2000 steps which I think you will be set at will give around 6V. So Leave spindle pulley Max set at 24000 and change the Steps per setting to 2400 and see what happens.?

Let me know.
