Please help me solve this February 04, 2014 05:23PM |
Here are some print that my machine did these days. I do not think it's z-wobble caused by the threaded rods (although I thought so and nearly bought aluminum couplers) after finding out that it's only twisted in the direction of y-axis. And the distances between the "waves" don't match the pitch of my threaded rod.
pic token along x-axis.(only it's not on the print bed)
token along the same direction as the one right above
token along the same direction as the ones above
same object but picture token along y-axis, but nicely printed(for me...) from this view.
Since when you see the print panel along x-axis, you actually see y-axis' movement. Therefore I think there's a problem on my y-axis movement. I have no idea on what to do in this kind of situation. I need help!
Any suggestion will be appreciated.

I don't think that's a problem...I have a 80mm fan heading towards the bed, always on because connected to the PSU. The object themselves did not move as I observed..
Strange aha?

The bearings are fine. Now my electronics are fried, but still I took some pictures.
I also installed something like this (before my Arduino and Aamps being fried =_=III) and didn't have too much good effect. I even sanded it to make it little effective to the linear rod.
Here's how my machine looks like:
I use 3mm filament. I now suspect the problem might be because misalignment of y-axis belt. When last time I tightened the belt, it wasn't fixed in the center between to space between the two pieces of plastic(as I observed). Although this assumption doesn't make too much sense even to myself.
This is what I mean.
(the belt is fixed there, not that free as shown )

I know it's been a long time. I got all electronics replaced, costing me about one hundred bucks. The problem just remains. I adjusted the little screw on the stepper driver and it does make some little differences. But still I cannot get a perfect straight wall whatever numbers of times I tried for.
I also found an interesting phenomenon. The pulley on y-axis motor shaft does not spin around it's center. I guess it's because the tensioned belt is only pulling one end of the pulley.
Is that a possible reason? If so how can I do that?
Any suggestion will be greatly appreciated!

Check me newest print out, plz
I now find that my wobble/banding is no in any pattern most of the time. My guess of the root of the problem is the tension of the 3mm filament. When the position of the hot end changes(sort of due to my printer's construction), the tension (both amount and direction) of the filament also changes. Therefore my next step, hopefully the last step, is to switch my filament and hot end to 1.75mm.
Any ideas?

Switched to 1.75, problem solved (95%, let's say it's solved)
Thank you to everybody who helped. Will post some pictures of newest prints later.
This is really a helpful community. Thank you!
Only thing bad about this experience is the bucks for the fried electronics...... Will learn from it.
