Trying to find good stepper motors

Post by guangkuokou » Mon Mar 23, 2020 12:50 am

I've been putting off things because I can't seem to find stepper motors that are even close to accurate that don't miss steps and lose their spots. I was looking at servos but they're $2,000 everywhere I look. I was just converting a Grizzly G0704 for my son to use. The Longs Stepper motors weren't any good at all, constantly losing their position. I was using a Nema 34 for the Z axis and Nema 23s for the X and Y.

Is there anything you would recommend? I can raise and lower the Z axis and be off more than 5mm almost every time or move X and Y and it will be off by 3mm and steadily move to one side.
has anyone bought this site https://www.oyostepper.com/ before, this is a china cnc part site.

Missed steps can be caused by lots of things. Can you describe your system? What kind of controller do you have? What is the model number of your motors? How fast are you driving them? Are you sure that your mechanics are not binding?
