Finally got some time to do some test prints again, and here they are!

I actually had to print these using the left extruder (still not figured out how to stop the extruder from going too far left when cancelling a build); right one still seems clogged even though I left it in pure acetone for at least 3 days!
As you can see the circle is almost perfect now, just a few imperfections which may now be down to the slicer and speed.
I got the bearing in only after hammering it in pretty hard. But I guess this piece is also designed to be like that to keep it in once in.
But as you can see after forcing it in, it's looks like a perfect fit!
So next question is how to loosen the bar so I slip these on? Note I have plastic pulleys on mine as well.

As I've said , we do Not think those bearing-blocks are needed on shafts !
It's a waist of time, money and filament to print and install them.
(they can Cause more problems and fix nothing)
It appears that you still have Settings Wrong !
It is printing an Open weave pattern,
the surface layers should Not have gaps between runs,
in outer layers of printed object, like that !
Should have a Solid, Filled look, when finished !
(run spacing needs to be about half what it is now)
Spacing may be set for 3mm filament instead of 1.7 size ??Last edited by EagleSeven; 01-17-2016 at 08:09 AM.

Not sure, will have to look it up later; it's on the makerware default standard settings.
Also on 30% infill.
Seems one of the wing nuts to level the bed has lost it's tread or something, wont change the level when turned.
Already ordered some new wing nuts from ebay.
Or might print some of these fancy looking knobs instead: http://www.thingiverse.com/thing:312187

I"m having this issue with the bed leveling, it wasn't the nuts in my case, but the armature that holds the bed. When tightening or loosening the wing nuts, the armature is flexing causing the bed to remain at the same position and making it impossible to level. I haven't fixed this issue myself, I'm currently looking for a fix (other than spending $150 on aluminum replacement arms).
I don't know if any of this will help you, but it's worth checking.

You can get metal stiffeners for much less than that !
here's first one I found in Search at eBay:
http://www.ebay.com/itm/3D-Printer-p...AAAOSwqu9U8FgB
(drilling holes in arms is required to install this type)
(I've read that they work very well)
You can also download Stiffeners object file from thingiverse.com and print them yourself.
That's what I did and they work Great !
There's another thread about that, with pictures, on this forum.
(Those have to be taped to original arms, unless you modify and add screws, but tape works)
(no need to disassemble bed to install them)

Couldnt find a run spacing option in makerware, or anything similar to it.
Filament diameter was changed from 1.77mm makerware default, to 1.75
Just Roof Thickness. Anything with spacing is to do with rafts and supports.

lol, well I found these settings only by selecting Edit in Text Editor in Makerware.
As you can see most of them are identical, except there are no layerWidth options, just layerHeight
Here's the full list of settings when editing with a text editor.

When you create a New Profile the 'Profile Editor' button will appear.
You Only want to edit New profiles, not the Originals.
Some commands may have been deleted from Original file.
(appears that many commands have been Moved from original place in list,
so there may be others Missing also ? )
These are definitely needed:
"layerWidthMaximum": 0.4,
"layerWidthMinimum": 0.4,
"layerWidthRatio": 1.48148,
(If you have an unchanged copy of that settings file somewhere, you should start-fresh with it)
It's okay to Move them in list, but None should be deleted.
I moved the ones I change the most to top of list.
Note: I changed the layerWidthRatio to 1.5 on ours and that worked greatLast edited by EagleSeven; 01-19-2016 at 08:10 AM.
