Hi!

As topic say, i'm doing a retrofit on an Emcoturn 120P (new ac spindle motor, new open-loop vfd, new closed-loop steppers, linuxCnc etc.)

but i have a question i can't figure out by reading the other retrofitting threads, the encoder for the spindle, most people removes the original and put's a aftermarket on, is there any special reason for this?

do they easily break? or is it problematic to get linuxcnc to receive the signals from the original encoder?

if i would to switch it for another one, what should i get? i have seen some people go for the CUI INC AMT102.

Best regards Victor
