Centroid Community CNC Support Forum

Hi everyone
Long time lurker and want to be centroider here

I now have a serious need for an updated machine

I've purchased a used extron CNC bed mill that currently is running a fagor 8050/8055m and DC servos

My plan is to collect required parts and build a new enclosure before pulling the ...

You can use scales and have realtime position feedback. The regular 4 axis Acorn relies on the servo/drive to do exactly ...

Hello and welcome to the forums.

I think either controller would work well for this machine. It does not require a lot of I/O.

It seems you have done some research and some thinking as you are correct that one of the common issues first time retrofitters run into is miswiring the drive control ...
