Cura 5.6.0 sliccing a 50 kB model into 20 MB, printing garbled garbage on CR-10s

[CreatingaCyborg 0]

I'm attaching the project file and the model. This is the bottom piece of a eye-tracking product stand that I made with FreeCAD. Can somebody tell me why this is printing garbage and why the gcode is so large? I have printed a couple test models that go with the printer. It's a little plastic dog. It prints great. It's just this model that seems to have trouble.

Your printer settings are for a 0.2 nozzle at 0.2 line width and 0.12 layer height.  That will make it a 16 hour print and a 19mb gcode file 613,000 lines long.

If you are printing that with a 0.4 nozzle installed in the printer then it will be severely under-extruded.

With a regular 0.4 nozzle, 0.4 line width, and 0.2 layer height it's a 5hr print time and an 11mb file of 352,000 lines.  Big difference there.

 

It's a simple model.  I'd go with a 0.6 nozzle at 0.3 layer height and 75mm/sec.  That knocks the print time down to 3 hours.  You can push a 0.4 nozzle to .6 line width but it would be better to have a .6 nozzle installed in the printer.

I recenlty tried this as a general "I'm tired of waiting" fix. Keep your lay height under 0.38 and you're good (I didn't beieve the math from Prussa to tried it... don't waste the filiament). For the most part you can't tell the diffence between 0.4 and 0.6 nozzles. There is some loss in edge detail and "fine line" but nothing I considered critical for strucural work.

Thanks for your input. I think that increasing the nozzle size will shorten the print. But, is this what is  causing my current print to be garbled garbage?

If you have a 0.4 noz installed but have cura set for 0.2… yeah. What nozzle is on the printer?

What material are you using? Lines that narrow aren't really enough material to adhere brilliantly in the first place, but if it's something like ABS, which has pretty terrible adhesion... well I'm not saying it would be downright impossible, but it wouldn't be easy. If you can't get good adherence on your first layer your whole print is just going to spaghetti.
