Help! I can’t bridge. Because I was having trouble bridging in other models, I thought I would try to print the Make Magazine bridging test (Thingiverse link). In the magazine, the TAZ 4 scored an impressive 5 out of 5 on this test.
My print looks like this:
… and from the side:
I can see the problem as it happens. When the extruder goes to bridge, the filament doesn’t stick to the source point. So it just squirts spaghetti into thin air. It does generally ‘stick the landing’, and after a few layers, it manages to print on top of the spaghetti pile.
Any ideas would be greatly appreciated!
Here are all the details…
I’m using slic3r 1.2.1 with fine_ABS_no-support_pt35nzl_pt14layer-6s.ini configuration file, with the single modification of “Bridges fan speed: 100%” (at the suggestion of Ray in Aleph support).
slic3r slices without complaints and produces this gcode file (dropbox link).
I’m using Lulzbot ABS black 3mm filament. I start the hotend/bed at 235/85c. The profile knocks it down to 220/80c after the first few layers. I have good first-layer adhesion.
