Extrusion misplaced and dimensioned wrong March 20, 2016 07:00PM |
Hi there,
I've got a CTC Bizer I (clone of Makerbot Replicator I) and I'm using Slic3r from the beginning and never had this problem before. I'm trying to print a kind of frisbee and while printing I saw the printer extruding about 2-4 times more material than necessary pushing the whole plate down and creating a relatively high wall. That made further printing impossible.
I think that it's noteworthy for you that I've got a "customized"
nozzle with a diameter of 1.725 mm which is registered respectively in Slic3r. I used it very successfully with ninja flex filament for seals for valves, however this model is supposed to be printed with PLA. I created the affected frisbee model as usual with FreeCAD, sliced it with Slic3r and converted it with the gpx command line tool to a x3g file. Standard procedure for me.
BTW, I'm using Xubuntu 15.10 64bit.
The stl and the fcstd files (see attachment) appear normal to me, but in Slic3r this happens:
⎡Note the red parts
⎤
⎣Luckily the printer did not try to print underneath the plate so far..
⎦
⎡Note the perimeter of the second layer⎤
⎣The yellow perimeters of the second layer are very oversized. As you can see they were planned to touch the plate⎦
If the option "detect thin walls" is enabled, Slic3r creates extrusion fragments on the top of my model as well, which are similar to the ones below the plate... I think it's an error of Slic3r, but FreeCAD is an option as well. To be sure I provide the stl and fc file I used as an attachment.
Thanks for your help!
