I have just installed the new hexagon hot end extruder assembly from Lulzbot on my Taz 4. Things have been going great until the last two days. I have been doing some prints only a couple hours long and about halfway through the extruder stops extruding!
I have investigated the issue and believe the two cap screws that hold the pressure on the filament when running through the teeth into the hot end are coming loose.
I have done a print with them completely tightened at the recommended 10mm distance and a couple hours into the print i checked the screws and they were completely loose!
Is anyone having this same issue? Hope I can figure out a solution soon.
