Good idea but I think I’m just going to try to take it easy on X and Y for now.
Thinking about it some more and after discussing it with a friend, I think I need to replace the X and Y leadscrews with ballscrews.
Vince has already pointed to the AB-nuts as a problem when he did his spindle upgrade, so I think the chances are fairly high that I’m running into the same issues he did.
A friend also pointed out that the Nomad doesn’t look mechanically ready for this. The leadscrew is fairly wimpy and it looks unsupported, all the cutting force is applied axially to the stepper motors, which is usually pretty bad for them. Vince’s teardown shows what might be axial bearings but it’s hard to be sure.
Vince has shown that putting ballscrews on X and Y isn’t too big a hassle and now that I’ve done a ballscrew on Z, I’m feeling a bit better about doing it on X and Y.
