re: The Official 3D Printing Thread

i have made a few. From all my research is that some beds come flat and some do not..... mine did not. I did the tape trick that worked to an extent but adding a BLTouch solved everything.

the other issue i had which is rather common and has different causes is under extrusion. I did the PTFE tube fix in the extruder, and didnt work. I replaced with an all metal hot end, didnt work. I had an order for a new extruder (EZR) and found a post on facebook about how some springs in the stock ender extruder are too strong and bind the filament.

This was my exact problem. The print would be fine for a while then i would get under extrusion simialr to a clogged hot end...the filament would be bit into and the extruder would jump, similar to what happens when the hot end clogs. but i fixed all that. Well I clipped off 2 rings of the extruder and i have been printing great since. I havent even put the EZR on yet and this was a 6 months ago. What was happening in my case was the heavy spring was deforming the filament just enough to cause friction in the PTFE tube. and as more and more friction was building up it would deform the filament more and more to the point of the extruder jumping and causing under extrusion.

It took me endless days trying to figure all of that out. So seems my ender was one with both major QC issues. but they are simple fixs IF you know how to do it.
