Non existent firmware  

RE: Non existent firmware

I have confirmed that PrusaSlicer is outputting this: M115 U6.2.3+8862

RE: Non existent firmware

I've checked to make sure that I'm using the latest version of PrusaSlicer and checked for configuration updates.

RE: Non existent firmware

I see what happened. When I looked at GitHub, I was looking under "Prusa-Firmware" instead of "Prusa-Firmware-Buddy". Why isn't this latest revision reflected on the Prusa3d.com firmware site?

Not sure what page on the Prusa3d.com site you are referring to, but firmware v6.2.3 is reflected on this page: https://help.prusa3d.com/product/mk4s

Here is a screenshot of what it looks like as of right now for posterity's sake (click it to see the full image):

I have noticed that this page sometimes takes a day or two to update from when a new firmware (or PrusaSlicer) is available on github.

This is because there are two (actually three) branches of firmware:

One branch is Firmware Buddy for printers based on the latest Prusa Buddy board (typically MK4, XL, CoreOne)

The second branch is firmware based on the older Einsy Rambo board developed by Prusa in collaboration with Ultimachine (typically MK3)

The third (oldest) branch is Ultimachine MiniRambo (typically MK2)

It is necessary to distinguish between these branches and it is up to each user. When someone visits Github, it is probably explicitly assumed that they know something (at least a little) about the problem.

RE: Non existent firmware

Is there somewhere (else) that helps users find the right firmware for their printer?

I have a MK4 with an S upgrade kit not installed yet. Same firmware?

RE: Non existent firmware

I always only look on Prusa's github page. The firmware for the MK4 and the MK4S is the same. There is a switch in the settings on the display menu on the printer to select between the two variants.
