Printer Messed Up

Hello everyone. I'm really nearing a point of just selling this 3d printer. I am so frustrated. All my prints used to be fantastic until randomly one day, they just started turning out like this:


The worst part is that I've pretty much tried everything to fix it. I've purchased a new motor, extruder and I got an e3d hot end, but it's still doing it. I figured it was a setting in repetier host, but I can't figure that out either. I know it isn't clogged, I know it isn't the filament because I've changed it out and when I extrude manually, it seems to work just fine. If anyone's got any idea, I'm all ears.

looks like it's underextruding, which extruder are you using?

Increase the tension on your extruder spring.

Made an similar mistake once. and in my case it took me a relly long time to find the error:

I had created a new filament in my slicer software, and unfortunately that one was set to 3 mm while I only use 1.75 mm Filament ....

Thanks for all the replies. The filament is still 1.75. I'm using the wade extruder. I've got it as close as it can.

Try increasing the temperature. I was having trouble extruding, the extruder kept slipping and grinding, resulting in prints like yours. The filament extruded fine on the j-head clone at 190c but has to be up into the 200s on the E3d hotends. Currently printing at 230c but I think I can probably lower it a bit.
