Hi.

I’m thinking of replacing my xpro v5 with the Root controller ISO rev. 3

I have a queenbee 1500x1500 Cnc (XYYZ, Nema 23) with a 2.2 kW spindle and Huanyang VFD (currently on RS485 comms.)

To this I would like to add a laser module with PWM control (0-5V) to “seemlessly” swithch between…

Anyone that have such a system and have a working .yaml?

Also what stepper drivers would you recommend?

Thanks.
