Thank you for the replies all . My first thought was as stated , disable anything not required to reduce hogging resources unnecessarily., and make sure it doesn’t time out etc.
I haven’t looked at this for a while , but I believe the motion controller I was looking at used a network connection, but would have to check .
This is the motion control board I was considering, but does it work with UCCNC ?
