Too much filament on Cura

Posted · Too much filament on Cura

Hi,

I am having a problem where my machine is simply pulling too much filament. It happens with Cura and ocasionally if I use RepG. Truth be told I don't want to go to SF, because its way more complicated and I'm getting good prints with Cura (as long as they are small). I mean, they have to be VERY small. If the printing is over 10 or 15 minutes the pressure on the Bowden tube becomes inmense, causing it to pop out of the clamp, or something else. In one ocassion the extrusion wheel got sort of "eaten" by the extruder motor plastic gear.

I tried changing the steps per e, but still, I'm down at 800 right now. Also my filament density (in preference window) is 1300, and the packing density (in the print config tab) is 1. Is that okay? What is the difference between those 2?

My filament is 2.89 exactly which is the value I'm using. Is there any other setting that controls extrusion in Cura? Something like flow rate??

Thanks!

    You should not randomly change you steps per E, use Curas configuration wizard to reset it properly.

    It sounds like you have other problems, not over feeding, which is pretty much impossible without a misconfigured step per E value. Packing, for PLA, should be 1. I'm not sure of the filament density value, never fiddled with it sorry.

    Thanks! I try not to change it randomly, I usually run the test using printurn with the extruder hot.I just tried puting it down a bit, but apparently its some other problem.
