I’m in desperate need of some help with my final uni show coming up in a few weeks.
I purchased a Wanhao i3 duplicator plus (also known as the balco touch) off of a guy from Facebook marketplace two weeks ago.
He showed me it working well, he has put a glass bed on it, upgraded the fan position - Got it home and it worked well for me for two prints. Then when I was happy with the printer i let it sit for about 10 days.
Now I can’t get it to work at all. It, is grinding on some extruder movements, i think on retractions which sounds horrible, please see video link. it is also doing some odd twitching.
it appears to be not extruding at all. Then i upped the temperature from 190 to 215 and 230. i am printing in PLA and this was working fine before at 190. going up past 220 sometimes gives me some material coming out of the nozzle.
I have cleaned out the gears, changed the nozzle, the ptfe tubing is perfect, no clogs.
I am really stuck now, i’ve tried printing with retractions off and still no luck, i’ve tried lowering the printing speed too.
Any help would be much appreciated, thank you!
