I have an older Sieg/Arc X3 CNC mill conversion. In fact one of the first I believe. It has developed some backlash in the X axis. It appears to be in the ballnut area or the ballnut housing. There is no backlash in the connector between screw and stepper. - I seem to remember that something here is prone to coming loose. But have checked everything I can see, short of dismantling.
If any of you guys can shed any light on the problem. I would be extremely grateful for your advice,
