Question #: 1034

Question: I've had my 3d printer working for a few weeks now with mixed results. My main problem is inconsistent extrusion. After about a half hour of printing, I find that extrusion slows down or stops. Tweaking the set screw helps sometimes. Do you have any tips for setting the tension or are you looking into any spring-loaded tensioners? I have the MK7 extruder (the one prior to what you're selling now).

Current Solution

If you are having issues with inconsistent extrustion, then that tells me that it may be the result of heat buildup to the hub and motor that is pushing the filament. Our new extruder does use a spring at the screw to compress the wheel against the hub on the motor.

Consider a cooling method to cool down that area of the extruder.
