prusa i3 trouble
May 27, 2014 01:46PM
So I bought the prusa i3 kit off eBay and finally got it setup. So my problem is it prints 1 side fine but the rest just has lots of gaps in the walls. Strange thing tho is when I printed a dome it printed fine. The square is mentioned to be a thin wall cube, the far right side is nearly perfect. I will upload a picture. What could this be?

Yep bed is level. Triple checked that because that's what it looks like it would be.

Don't know if this has anything to do with it but when I press x home it doesn't go home I have to press it a few times and it slowly moves there. Once it's there, say I say go right 100 it moves fine but if I say move back left 100 it only moves about 10? Any ideas?

The belt is tight, tighter than the others really and there fine. Yes there is a flat why? Why would it be bad on 1 side of the print tho bit the other fine?

If your printing with pla you need a fan blowing onto the piece your printing so that the layer is cold for the next layer

I printed without a fan for a while when I first got into it, and again when I "upgraded" to an E3D, never has this effected in any noticeable way a calibration box. That dome should be more messed up due to lack of fanage.
I would guess E steps/mm, but again, your dome printed fine. Just to be sure, you have calibrated that, right?

I checked them and they all seem fine. It did say that it's already fully calibrated. It's just so strange that 1 side is fine then it gets progressively worse as it gets to the left...

I've had that before, but it was from underextrusion, the symptons were a bit different, but the same in that it was fine on one side and transitions to worse on others.

Might chech for a bad motor connector,a square would be more "jerkey" then a circle, maybe something is shaking loose.

Looks like a belt is loose, but I'm sure you've checked that already.
