I am trying to get my Express to work out of the box. I’ve spent some time now trying to get the Z-axis to function properly [Y works great; X is close but I’m going for one thing at a time here.]
The hardware on the Z axis is struggling to say the least. Sometimes it can move mostly up or down, but never all the way. The load is quite high and seems to be labouring.
-
One issue is just that in neutral, non functioning mode, the whole Z axis can sometimes just…fall? It spins with gravity right to the bottom. So I tighten the wheels and check the spacers, whether tightened or loosened, it still happens.
-
In both up and down directions, it will occasionally do a 3 move stutter and give me a relative movement error. Not always, but sometimes.
-
If it ever actually moves more than say 300mm without a stutter, it sure sounds like she’s struggling. Like the motor can’t handle the weight.
Thanks for your time, I’ll listen to any advice.
