I’m attempting to print a customized infinity cube with support for PLA as snug support at interfaces and using a 0.2 nozzle 0.06mm layer height. Yes, it is overkill, and I just want to know that I can do it and to see the result when it succeeds.
I am getting into constant problems of filament getting stuck in the nozzle at about a quarter of the way where the support interfaces start changing between my generic PLA silk and the support for PLA. Every solution is a cold pull or hot purge of the filament using the 1.5mm hexwrench, and it works again.
Feature request, give us control of the system and remember where we left off, so that I can give myself room to clear the nozzle without having to cancel the print. I think my last attempt skipped layers as I was pausing and trying to fix and then resuming, because it was floating high when I solved the problem and got it working again.
On some occasions, the silk broke and then was forcing itself against metal only to get stuck trying to be pulled back. Other occasions, the nozzle has been heated and yet, even a hard drive with the wrench can’t get it to push through, as if the nozzle fan is too powerful and a little heat creep is needed.
Another design optimization would be to have a small secure PTFE tube piece guide the filament from the gears to the nozzle, because the slipping and snapping is not good.
Before attempting Support for PLA, I was using PETG, but the speed of the nozzle over the PETG would eventually tear the PETG lower layer apart after a filament change at about the same point as the purge failures above.
I dried the filament before printing. Now I want to try and adjust the nozzle fan speed to be a little lower, but I see there are no controls for that. Any support for this is appreciated.
