Feed cog wearing through filiment
I installed the Titan Aero on my printer and am having an issue with the feed cog grinding up the filament. 1.75mm mirrored unit. Ive double checked the following; Pinion flush or slightly below Drive gear Minimal “backlash between gears to achieve smooth operation by hand Extruder stepper set to extrude 100mm of filament when given proper G Code Temp sensor set to Type 5 (marlin) Screw 3 not overtightened Retraction set to 1mm Help greatly appreciated, I really need to get this machine working. Only abnormalities I found during assembly was in checking resistance on a 12 V 30W heating element I got slightly over 5 ohms. I on inspection I would suspect the notchy “budget” ball bearings will not last long in this high heat environment.
