Hello,
I made a cube with 0,5mm walls. 3 of the walls are with 0,54 (measured with micrometer)mm in my tolerance. But the backwall have a measure of 0,61mm. I slice with Skeinforge 50. I dont know why the backwall is different to the others . :confused:
And how i can influence the wallthickness? I tried under Speed "Flow Rate Setting", but it doesnt have effect to the print.
Can anyone help me?

PS: Sorry for my english, greetz from northern germany :D
First - Is your printer aligned?
I can get similar issues when its is not aligned or loose belts.
What is your printer (brand or type)
I generally use slic3r for prints and this has some good options.
Flow Rate might not help with the wall thickness.
What size nozzle?
Hey, thanks for your answer, what do you mean with aligned? My printbed is aligned. The belts should be right, but i will check it tomorrow. Its a Wanhao duplicator 3 ( makerbot replicator 2x replica i think) nozzle is 0,4mm.
I thought already about to change from skeinforge to slic3r, maybe i have to make this...
cu and good night ( here it is 10:36 pm :D)

Hey guys,
its me again. The main belts are tight, the secondary belt (aidbelt? Or how called this belt between stepper and shaft of mainbelt?) was a bit loose, i fixed it. But I cant imagine, that this is the point. And why the single line extrusion should have a other width, when the y-Axis belt is loose?

aligned meaning is the bed perfectly level? if your bed is a little tighter to the nozzle in the back then the line will be squished a little more making it wider. however, that should only effect the very lower layers.
I leveled my bed again. It was closely perfect. But after leveling i have the same problem. I can notice, that the back lower layers have the normal look,but the higher layers at the back push them each other away. The higher layers have 0,7mm and the lower layers 0,59, though still too thick.
In second try, with corrected perimeter, the three walls have 0,51mm, the lower layers of the back 0,56 and the higher layers of the back 0,62mm
We use Slic3r, and have never seen this issue.
Is the back wall defined any differently in your 3D model?
Is your printer laying down a straight bead (just too thick), or is there any zig-zag stitching going on when that section prints?
How does this compare (head movement) to when the other walls are deposited?
I dont made the model, it is from the rep rap calibration site. Its a straight bead and the headmovement is similar to the other walls.
Then I will change to slic3r in the next days. Hope its not difficult to change from skeinforge to slic3r with 2 extruders.
On the levels where the back wall is thicker, do the side walls get thicker as they get closer to the back, or are the side walls at that height a consistent thickness front to back?
The side walls are untouched. And the higher layers of the backwall arent thicker, they only have a offset to each other.
Oh, offset is another issue entirely. I'm surprised that the rear wall is offset but the front wall is not - that sounds like it's in the code.
If both front and back were offset the same, I'd say you were losing movement, sometimes due to friction or not enough power on the motor that handles that direction.
I hope offset is the right word for my problem :D It is so, that, in example Layer 25 is at y76 and layer 26 is at y76,3 and the layer 27 is at y76 and so on(only for example, i didnt read the code).
I have configured slic3r yet, but I have the problem, that my printer needs .x3g . Do I have only the possibility, to slice in slic3r, import in ReplicatorG and than export as x3g? It seems me to be awkward.
Originally, I though you were saying your rear wall looked like this (cross section):
XXXXXX
XXXXXX
.XXXXX.
.XXXXX.
..XXXX..
..XXXX..
..XXXX..
..XXXX..
..XXXX..
..XXXX..
But now it sounds like you're saying it looks like this:
XXXXXX..
..XXXXXX
XXXXXX..
..XXXXXX
XXXXXX..
..XXXXXX
XXXXXX..
..XXXXXX
Is that right?
Yeah, but only in the upper half, like so:
xxxxxxx..
..xxxxxxx
xxxxxx..
..xxxxxx
xxxxx..
..xxxxxx
xxxxxx
xxxxxx
xxxxxx
Right. Sorry, no clue.
If the front wall isn't doing the same thing, then it's happening because the code tells it to.
OK, I will check the code and will make the first print with slic3r tomorrow.
So, i solved the problem. Apparently, Im too stupid for slic3r (need a start.gcode for two extruders, which works with my printer). Therefore i tried it with Skeinforge 47 (Legacy). with 60mm/s same problem, but with 30mm/s i have all 4 walls perfect.
But what is the reason?
