I am trying this t-glase stuff on an e3d v6. I also regularly print with abs and pla. Lately, my abs filament destroyed some nozzles (leaving helix-shaped cuts on the inside of the nozzle and thus increasing resistance insanely). First I thought it was a bad spool and got a new one. After printing with t-glase, I hot-pulled it and fed abs for another print using more or less the same temp for both, 235 deg. After not even 1m of extruded filament, I got a really bad blockage again. Will have to inspect the nozzle first for the helix traces, but just out of the blue: Does this ring a bell for anyone? Could there be some weird reaction going on between t-glase and abs?
A short update: I recently also tried out taulman bridge, which is a cool material to print with. After a few parts I went back to pla. To do so, I hot-pulled the bridge, revved up the heater a bit (250° C) and waited for the hotend to stop dribbling out leftover bridge, then lowered the temp and started feeding pla from about 240° C on downwards to the 220° C I usually print pla at. I prorgressed to extrude a meter or so of pla to make sure it wouln't clog. All looked good and I had a couple of parts printing nicely, before it jammed again. I never had pla jams before and generally my machine is really reliable. But whenever I change from a nylon material back to abs or pla, the trouble starts. So I guess I'll have to use dedicated nylon nozzles from now on. Does anyone know of a good source of information regarding material change practices and dos/don'ts?
Following. I recognize this problem. I usually take the whole business apart and heatthe nozzle over a gasflame. Seems to do the trick. Cheers.
I am purchasing a Big Box but also currently have an Ultimaker2. Before every filament change I do an Atomic Pull to clear the nozzle. This is especially important when changing materials on an Ultimaker to avoid clogs. For those of you who don't know, an Atomic pull is described here. http://support.3dverkstan.se/article/10-the Do you do anything to clear filament when you switch?
