INDX & Buddy 3D Camera

Tom De Winter — Sat, 02 May 2026 15:23:37 +0000

I'll be starting the build of my Core One soon while I wait for my INDX to ship. I see some advising in the build instructions to route a USB cable for the Buddy Cam making later addition of the camera easier.

Do any of you know if the Buddy Camera will be compatible with the INDX system?

MMU Boot Rattle

GregorPrinter — Sat, 02 May 2026 12:32:02 +0000

Hello everyone, I recently installed my Prusa MMU3 on a Core One printer and I’m experiencing an issue during startup.

Right after booting the printer, the MMU starts moving and produces a loud rattling noise for about one second. It sounds like the idler is trying to find its position. After that, the unit seems ready and no error messages are shown.

I did some research but couldn’t find any videos or examples where the MMU behaves like this. In other setups, the idler appears to move smoothly to its end positions without noticeable noise.

I already checked the following:

The idler drum rotates freely
The small gap to one side (as described in the assembly instructions) is present
The idler is firmly mounted on the shaft
on both the MMU and printer is up to date
No error messages are displayed

Despite all of this, the rattling noise during initialization remains.

Has anyone experienced similar behavior or has an idea what might be causing this?

THANK YOU SO MUCH

Feature: auto-clean delete Prusa Connect Files

Hey,

I recently run into the Issue that i couldn't upload print files though Prusa Connect because the Cloud Space was full.

Then I noticed that there where a decent amount of files saved, that wehre blocking the space.

Shouldn't those files be deleted after a successful download to the Printer?

Best Regards

I strongly advise against buying a Prusa XL or Prusament PCCF.

I recommend NOT buying the XL or Prusament PCCF in 2026. I am an experienced 3D printer, having started in 2016 with an Original Prusa i3 MK1. I bought two rolls of PCCF for my XL and have gotten ZERO successful prints out of that 220 dollar investment.

Updated firmware. Downgraded firmware. Upgraded firmware. Printed mods. Removed mods. Enclosure. No enclosure. Glue, no glue, stock settings, tweaked settings, firmware errors, parking issues, dropped support for my 5000 dollar printer. Clog after clog, multiple nozzles, large, small, stock. HF, not HF, hardened and not hardened.

Support for the XL: Zero

"Flagship status" claim: Completely superseded.

Today, it clogged while I was at work on an 8 hour print. I came home, fixed it. Thirty minutes later, I had a giant PC blob of death, ruining the hotend, the print, and finally, my relationship with Prusa. 2016-2026. I'm done. This printer sucks. Mine hasn't worked reliably since 2023, and in 2026 (eons of time, per many people on this forum), it still doesn't work.

I owned ten MK3S/+. I brought one to Antarctica. They were great. I strongly support Prusa's open source ethos. I cannot condone the lack of support for this printer.

The abandonment of the platform was the first straw. The realization that, yet again, I cannot get my 5k printer to work after following all troubleshooting, after a decade of successful printing on Prusa's platforms, was in fact the final straw. If yours works, good - I am very glad for you and hope you get many more great prints out of it. Mine doesn't.

Buddy camera reports “WiFi connection failed” Whenever I try to use it.

Tried different cable and relocating camera with same result.
