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.
