Fellow printers, I’m trying to get my A20T working again— my wife asked me to do a project for her which requires the A20T. Two of the three filament paths are clear (I can manually push cleaning filament into the top Bowden tube and it comes out the nozzle). However the third path is really plugged...

Fellow printers, I'm trying to get back to printing with an A20T. I had frequent extruder jams in the past. After you finish a print, do you just let the printer cool down or do you retract some filament, or pull back the bowden tubes? Any suggestions for avoiding jams? Any preventative maintenance?

THANK YOU! I had given up on the A20T, but I'd like to try getting it working again. I'll try your suggestions.

No. I gave up (temporarily, hopefully) on the A20T because the nozzle keeps jamming...
I never did get a working prusaslicer profile set up.

Fellow printers,
I’m using a Diamond 3in 1 out nozzle but having lots of problems with jamming. The nozzle came from Greentree...
Anyone had luck with the Diamond nozzle?

I found in Geeetech’s scattered documentation that the flow rate of the extruder is about 24cc/h which works out to 6.6mm^3/s, which is about what I’m finding. I’m still curious what flow rate others are using to minimize the extruder servo “clicking”...

Never mind... figured it out.

Fellow Printers, I have a I3 pro C with 3D Touch. The auto leveling only picks a single point in the center. I would like to use the most accurate auto mesh leveling available in Marlin 2.x for this printer and 3D Touch. Do I recompile Marlin with “ //#define AUTO_BED_LEVELING_BILINEAR” uncommented?...

Fellow printers, I’m having problems with the extruder steppers “clicking” during a print. The filament is set up so there is practically no friction coming off the spool. I’m using PLA at 215 degrees. Both extruders seem to click about the same amount. I’m worried that the extruder can’t heat the f...

Fellow printers,
Seems most times I try to print another test on the A20T, at least one of the three extruder paths is plugged. Any ways to avoid this?
