There’s a sieg user group on Facebook which has a couple of cnc’d 2.7s, if you’ve not seen that already. Useful to see what others get up to.
Have you got a wiring diagram of your inputs / outputs from your breakout board to the servo drive and vice versa please?.
I recently got a 1.8kw one for the spindle on my amat25 conversion.
