So pro5 + router/spindle amb fme-u 1400 di

[WillAdams (William Adams (Carbide 3D))]

There is a bit of discussion on connecting the voltage from the controller at:

Mafell Spindle with manual tool change FM 1000 WS or PV-WS

If it’s 0-10V it’s probably analog, and you can get cheap PWM to analog voltage converters from the usual suspects. ( https://www.amazon.ca/Baoblaze-High-quality-Voltage-Converter-0-100/dp/B07CNRWB2C). The ones I got from AliExpress can accept a wide range of PWM input. You will need to set the min/max spindle speeds, some light unverified googling says $30 and $31 will set this. This will then control the PWM output for a given RPM and “map” it appropriately.
