Re: Over extrusion bug
Extra extra info. I'm set my app to run as a post processing step and there are errors in most files. My criteria is that the line width must be <= the indicated line width * the greater of the line width multipliers. Most errors are well below the 0.64mm^2 cross sectional area limit that triggers t...

Re: Corners Bigger Than Body
I think you missed the second part. Your extruder is over extruding every time it slows down or stops due to the built up pressure. That's why every corner is bulging slightly. There is no setting in S3D that can help that. Klipper implements a feature called pressure advance which basically does an...

Re: Corners Bigger Than Body
If there's only one bad corner now then it sounds like overshoot which is probably a loose belt. That's the simplest answer anyway. The more complex answer is that it seems like it's for all corners, it's a known problem which Klipper is designed to fix.

Re: First layer massive gaps
Don't suppose you've accidentally set the first layer line width instead of the first layer speed?

Re: Over extrusion bug
Further experimentation: By changing the X offset I can make the error change lines, or not appear at all. In the attached file, if I use any offset from -187.99 to -187.91, except the calculated value of -187.92 the error is not present. If I shift the model to an integral offset the error changes ...

Re: Over extrusion bug
Thanks for your response. I've resliced the original STL and the bug as reared its ugly head again. I've hit this bug on another model as well in recent days. HDMI7_Uni_Lid_v24.test.gcode On lines 788 and 795 you'll see the same off by one error. I've written a little app to find these lines btw. I'...

Over extrusion bug
I believe there is a bug in the gcode generation which is triggering an error state in the printer firmware. The bug only seems to appear on the attached model with a 0.2mm layer height and a 0.4mm line width. If I change either of those parameters the generated gcode is clean. The stl attached is a...
