Re: Nozzle cleaning
I also preheat the nozzle in every Gcode file with M109 and M190 but I think the filament from the previous print job gets solidified both in the nozzle and the nozzle throat (barrel inside the heatsink) and the preheating cannot melt this filament in the nozzle throat. Melting of the filament in th...

Nozzle cleaning
A few minutes after finishing a print job, the filament is solidified in the nozzle and the nozzle-throat.

External cooling fan that is pointed towards the part that we are printing. 2. Extruder fan that helps cool the extruder drive mechanism, Ramps 1.4 has D9 connector for a fan c...

Hi, Thanks for your message. Normally the brass nozzle is at the bottom of the aluminium heat sink and the tube adapter at top. I can push the teflon tube just inside the adapter as much as it goes down. By the way, I've been playing with PID settings and after a manual correction, I think I obtaine...

I tried all configurations ...
