[BUG] TMC error points to non-existent error page (MMU2)

[PxT]

Printer type - MK3S Printer firmware version - 3.13.2

MMU upgrade - MMU2S MMU upgrade firmware version - 3.0.1

SD card or USB/Octoprint SD

Describe the bug Received a TMC Driver Error message during a print that points to prusa.io/04321 however that page does not exist and just redirects to the main prusa3d site.

I was able to find the correct page with Google but that text only mentions MMU3 and not the MMU2 on my machine.

Thanks for reporting.

This is not on the firmware side but a routing error across our websites. This error has been fixed now.

Hi PxT,

do you find a solution for the problem?

@duebelpapst Installing the PD board solved all the power issues and driver errors for me

@PxT From were do you get the PD Board, I can't find it at the Prusa shop.

@duebelpapst This isn't really how GitHub is supposed to be used so I'm not going to link to a 3rd party site, but a quick google for "prusa PD board" should bring up a source. Prusa does not sell this part separately for some reason.

@PxT Thanks, I had already found it, just thought you had managed to buy the part from Prusa. At the moment the MMU2S is running after I increased the voltage on the power supply from 23.9V to 24.5V. But in the future I will supply the MMU2S board directly with a step down converter with a little more than 5V, which I will connect to the 24V of the borad.

The PD board has recently been added to the official Prusa store. 🙂 https://www.prusa3d.com/en/product/mmu-pd-board-addon/
