Hi all, I got my Lulzbot mini a few days ago and have been putting it through it’s paces. I have printed a lot of little models with fairly good detail and resolution, however, I have yet to be able to print anything at all that was designed to fit together and have it work.
I’ve been looking at a lot of forum posts and tried many things and so far nothing has fixed my issue. I read a few posts talking about adjusting the print temperature, and also tweaking the flow settings. I have double and triple checked that my average filament diameter is set correctly.
The photos I have attached are of a calibration cube that is not quite a cube, the z dimension is pretty good only about 0.05mm out from where it should be, the x dimension is the worst, about 0.2mm too large, and the y is about 0.1mm. There is also some surface defect on one corner in particular. The second object was supposed to be a 0.5mm thickness wall test, as you can see it was fairly well botched, the wall thickness is just shy of 1mm thick.
This is ABS using Cura with the Lulzbot normal quickprint settings, occasionally adjusting the parameters mentioned above with no real change in print quality.
If I lower the flow rate further, the top layer becomes very rough. Thanks for any feedback you can give!
