I have a problem that makes me want to sell my taz 5. About a week ago I left home during a 11 hour print. When I get back the spoil of filament has finished with about 40 mins to go and had been extruding nothing for that time. I didn’t think anything of it and went ahead and ordered some new filament. When the new filament arrived, it started grinding it. I changed back to some filament I’ve used before and that grinds too. ABS was also grinding.
It’s not heat creep because I’ve solved that issue. I’ve changed idler settings, temps, taken apart the whole extruder to no avail.
I even went ahead and bought a whole new hot end (0.35mm) and the same thing happens. I’m absolutely lost. I need some help please. Lulzbot are terrible with support especially for those of us who don’t live in USA. I can’t even send my printer for repair. Does anyone know what might have happened? Is it a heating issue? Although the temps are constant on the display.
I seem to be able to extrude in the air 7 times out of 10 but when I start print, it just grinds the filament. It almost seems like the filament moves left and right whilst the gear is pulling it.
Please help guys I’m in deathly need of it.
