Problems with high tollerance filament (under 1.70)


#1

Hi everyone, unfortunately Im having some problems using an abs (not zortax filament) that dont have good tolerances (the diameter drops below 1.70 reaching sometimes 1.65), on other machines I have no problems, but on zortrax M200 (as you know have a fixed filament traction) my prints stop because the m200 are unable to pull the filament … has anyone try to find a solution for this problem? Maybe putting a circular shim on the bearing? By doing so i think the extruder gear can “squeeze” the filament with more force … (Considering that the extruder gear cant be modified). I’d like to have your opinion …

I think exists small assembly tolerances for extruder motor screws. You can try to loose motor screws a little then push the motor to bearing side in same time tighten the screws, maybe this can help a little.
