500 air cooled spindle speed control

Xeno108 · July 17, 2020, 6:01pm

I’ve seen some spindles on Amazon that have a 0-10v input that seems to control speed (called mach 3 input for mach 3 software I assume)

Can we take advantage of this to control speed using the Rambo board?

Not directly. I don’t think the Rambo can do 0-10V TTL output. But I’m sure you can get a converter board that will take the 3.3V or 5V TTL signal from the Rambo, and boost it to 10V.

I am using one of those spindles with RAMPS and also needed a converter from a 5V PWM signal to 0-10V and found this diagram in ESTLCAM that is working for me and is really simple
