I am using mattercontrol and everthing is set just as the directions say.
I noticed that I was having some major bed adhesion problems especially with the loops around the print to prime the nozzle. After I calibrated enough to get those loops to stick (I just picked a print and printed the first layer a few times) when the machine actually went to the print itself the nozzle could barely squeeze out filament at all.
I then spent about two hours adjusting the radius and calibrating. I noticed that I had to loosen the Z axis screw by about 3mm more than the rest. I think that may be a symptom of my problem.
Well when I started trying to print again I noticed that the first several layers of my prints would shift over by about a mm/layer. It would then finish the rest of the print on the last shifted layer. It would shift away from the Z tower, the one I had to loosen the screw by a lot on. I also tried printing a few other things, making sure that the problem would follow, but it only did half the time. This points me in the direction of a software problem, since it only happens on some, more complex/bigger (not by much) prints.
Nevertheless, I started looking for a mechanical problem because software is an unlikely cause for failure.
I thought, ok the nozzle is catching on the print, causing the Z belt to skip, so I spent another hour leveling. This was the next print:
This is pretty much where I am now. I am printing a benchmark print in the form of an owl, which seems to be doing quite well.....
Nothing is consistent. I can't pin anything.
Thoughts?
EDIT: I solved the layer shift problem, the Z stepper was not securely attached to the gear, which was slipping a bit.
The motors are still getting fairly warm though....
