SBRP - that's the first time I've heard that name for phenolic. Got it. Thanks.
Your build is phenomenal. Well done.

Concerning a new VFD and MODBUS: I just recently set up a Hitachi WJ200 on the bench. I initially used 0-10v analog signal to control speed but the RPM drifted around somewhat due to electrical noise. It wasn't bad but I wanted to experiment with a digital solution. I was leaning towards MODBUS but not with much enthusiasm; Lots of configuring, several different components, driver's etc. Fortunately the Hitachi has a pulse stream input for speed control. I set up my spindle control in UCCNC to use step and direction output, connected the pulse stream input of the VFD to an axis output on my BOB and a little tuning later had it working very well. 2 wires, no driver's, no adapters and no RPM drift. Just a suggestion.
