Question Troubleshooting and tuning printer for printing Voron parts

[le_chiffre]

Hi, I'm new to 3D printing. I have an old V2.2 (I built it and never used it) and I'm trying to print parts to full upgrade it to V2.4.
I started with the Z Drive and this are my poor results. Can you help me to diagnose the most obvious problems?

Some additional, maybe useful, information:

• I'm using a bowden Mobius extruder with a E3D v6 hotend.
• The spool of ABS used has been open and outside its dry bag for a year.

Final question. Do you think this parts are "functional enough" for a printer, or I should ban them from the face of the Earth?












Thank you very much. Have a nice day.

I am not sure if it's the camera or some of them are a bit warped, but overall they look useable. Maybe a bit overextruding, just a tiny bit. I would say they are good to go, just checked if they are not warped too much especially in places where they go against other part.

I also think they should be usable if both halfes are matching and fit together.
I would check if the bearings and that the bolts fit.

Yup, that's probably the most important.

Yeah, I have some warping in a couple of parts. The warping is present "at the same side" in all those parts. Like, the warping is always present at the left side of the parts that were printed at the left zone of the bed.
Any other observations? In the second picture, the rightmost holes looks weird. Maybe I should speed up the part's fan?
Thank you

I bet you should toss that filament or try and dry it. But like others have said, as long as the parts fit they might be usable. Just sand the parts that are not flat.

Maybe uneven heating on the bed, maybe try to print one part completely on the right side an check if it has the same distortions.

I would just make sure that the parts for the A/B drive at the gantry are completely straight, else it gets painful to get the gantry square.
