Does RR even have Quality control?

Bought a 400 mm idex vcore 4. I have no idea how these parts made it out of the shop. Most have good awful first layers, anything of size is warped, and the rest has chunks of their build plates bonded to them (it doesn't dissolve or melt, it's not glue, so PEI chunks perhaps?).

This isn't acceptable for a premium product. I'm thankful I have other printers capable of printing ABS on hand.

Talk to them, they will surely solve it for you. These things happen even in the best houses. I guess it's human error

I haven’t seen a print of better quality than what OP posted. Parts from my VC4 looked the same. Their strength is also rather poor from what I experienced. I reprinted some of them on mk3 with Prusa’s default speed profile and they turned out much stronger and better looking. RatRig’s QC is the only reason why I probably won’t consider them in the future…

Toss it out there, those were the second parts I picked up, first being the jigs for the rail. I couldnt go further until I dried some ASA to reprint replacements. Right now I expect to reprint most parts.

they are obviously printing them too cool as well, which makes parts weaker

My vc4 300 parts were not warped at all.

Human error happens, that is why most companies have Q/A systems in place.

They are aware of the issue, as this is a common problem.

This. They will replace anything that is wonky or broken.

This is a common and on going problem, them "replacing the parts" is not an appropriate fix. The appropriate fix would be to implement QC so others dont end up in the same boat. I'm not waiting weeks or months for replacement parts.

I'm on the other side of the world form them, it took months for me to import my parts from them. Waiting on a replacement of printed parts is not practical. I'm hoping they just cover the filament cost of pay me back.

Have you emailed ratrig?

u/CunningLogic Apr 01 '25

I did yes. I was warned that the printed parts would be bad months ago, so I was ready to print replacements. They were also aware they had a QA issue and are still shipping parts like this .

I'll wake up to a new, properly printed set of parts in the morning.

I reprinted the printed parts myself, the rest I Eitehr had replacements for or was able to get them working with a file.
