I think you guys have identified part of what I have been missing. I do not know if my BOB does 0-10v output for PWM. I don't have any instruction for it so may need to plan on buying one that does. The VFD manual does reference the 0-10v control so will likely do it if I had a BOB that was capable. I was confused why my laser works fine on PWM, but as I have looked into it more the laser only needs 0-5v to work. Now I see why the spindle PWM is different.
Will keep you posted after I get a new BOB.
