Getting rid of the OOZE in a dual extruder setup
jhud...@gmail.com
- using PLA and I have tried multiple types and manufacturers
- tried using temperatures of 180 to 230, (low temps help, but not much)
- the PICOs are cooled by fans just like the instructions say, but I have also tried different spacing, fan speed, and different types of air ducts.
- I am using 0.35 mm and 0.4 mm nozzles, which came in the PICO kit as well as some aftermarket ones
Here are some of the things I have tried:
- drop the temp when switching extruders - I have to drop the unused extruder by over 20 deg to make any difference, and when you do that, a glob sticks to the tip and then runs into the model.
- retracting the filament on unused extruder by 10mm to 20mm. Actually, a long retraction like that just increases the chance of the filament getting stuck in the PICO when you switch back to it.
- I tried putting a skirt around the part, but the ooze was so much and so fast that the skirt wasn't able to catch all of the ooze.
Does anyone have some ideas?
(switching to ABS would probably help, but the fumes are a bit much, and I just like PLA better)
