Topic: Wired E3D v6 jamming issue after printing PMMA filament

So I recently picked up a roll of PMMA Filament (https://en.wikipedia.org/wiki/Poly%28me … crylate%29) after printing some test prints I wanted to switch back to my usual PLA and it jammed sometimes but sometimes it worked. After heating up my hotend to 250 and extruding 5m of PLA plastic it worked again (I unloaded the PLA 4 times at 90°C). Have somebody exprienced similar issues when printing high temp plastics with the v6?

You will have this issue any time you run high temps then go back to lowers. You have to load the lower tempt at the higher temp and purge a few 100mm through to flush out the remaining high temp stuff. other wise it will not melt at the lower tmep and cause a clog.

Printing since 2009 and still love it!

But usually if I am printing ABS and I want to go back to PLA I extrude 300mm-400mm of PLA at 230 and it works fine. But I wasted 5m of PLA trying to flush out the PMMA.

If using an E3DV6 hotend on a Da Vinci printer, do as I do, on some of my other printers. Heat up the hotend a few degrees above recommended filament temp. Once temp reached, push down by hand on the filament and then immediately pull out. Works everytime and leaves a clean nozzle.
