My i3 Rework is kit from Replikeo w/ J-head HE. I had it for about 6 months, didn't really print much. For the past few days I'm unable to print anything for longer then 10 minutes it clogs every time.
I'm using 1.75mm white ABS filament. So what happens is it prints fine in the beginning and then it stops extruding (hobbed bolt just digging into filament) but it's not moving. When i remove filament it doubled on itself (not sure if it's normal either). I tried reloading it several times, cleaning nozzle with wire, etc... Tried varying temperature (from 235 to 245) still no luck. And it worked before! Is there anything I can do? I'm ready to buy new hotend if that's what it takes just not J-head.
Also since day 1 I was never able to insert filament without struggling for good 5-10 minutes, especially 3mm. Even 1.75mm filament doesn't go in until I spend few minutes. Is it normal, or my hotend is not very well aligned?
