Hi, it’s me again. Using parts entirely bought from you.
X - my rollers move a little independently of each other. The one farthest from the middle assembly gets a little bit ahead of the other. This is especially evident if the machine is going back and forth rapidly - the X roller on one side moves a lot more while the one on the other side almost remains stationary.
Y - it still feels rough when I move it by hand, and while the machine is running, that seems to translate into kind of bumpy/jerky movement. I’m holding out hope it’ll smooth out with use. Due to other problems I haven’t been able to tell yet if it really affects results.
Z - I have that “diving” problem I’ve seen elsewhere in this forum. Seems that under certain circumstances, and I still can’t really tell which ones (except it only happens while running, not under manual control), my Z motor makes a loud buzz and doesn’t turn when it’s attempting to go up. It only happens a few times while running, too, not every time - but the result is that the tool just gradually goes lower and lower until it starts to get buried and I kill the process.
Any ideas? I’m hoping the X issue is just that I didn’t tighten something correctly, and the Y issue might work itself out. I was able to find the most mentions of the Z thing here in the forum, and I tried a couple of the solutions but nothing seems to solve the problem entirely.
