Taulman PCTPE filament slip workaround

[robyneil @robyneil My Robox is a Blue Commercial Version]

May help someone or please let me know if this is bad thing to do. A workaround on incessant filament slip warnings with the flexible Taulman PCTPE seemingly is to let the nozzle cool down to around <= 43 degrees (15-20 minutes) before clicking Clear and Continue to resume the print. PCTPE seems to have a lot of filament slip problems from scanning forums.

I’ve been experimenting with the Taulman PCTPE for a week now and have been getting problems with incessant filament slip warnings. Even if I choose to Clear and Continue, I eventually would hear filament popping, see steam puffing out and get the filament slip warning again. Worst, the steam would sometimes condense on the extruder and produce dark amber colored sticky blobs. Eventually, I’d just stop the print since it’d take forever to keep clearing and resuming. I inspected my dual extruder head and everything seems fine by the way.

Basically, I had to cancel a couple of large prints when they’re around 70-90% done. It is a damn shame since the PCTPE prints looked better than my ABS prints. Support material was easier to remove as well.

Changing the nozzle temperature from 225 to 215 seemed to have solved the puffing steam problem and occasional amber blobbing, but I still get the filament slip warnings. Finally I found that when I do get a filament slip warning, letting the nozzle temperature cool down first keeps the filament from slipping again and finish my print. I’ve done this with 2 prints now and will continue doing so.

Attached is a a print of MLP Spike with Taulman PCTPE. Cura unfortunately didn’t slice the eyes and ears properly but everything else looks fine.
