Fun discovery of the day: PrusaSlicer (at least for the Mini) actually _enforces_ the machine limits by emitting appropriate G-code when slicing. Among other things, this means that if you want, say, higher accelerations, you can just request them.
This is probably because the Mini can't save anything to EEPROM, which means any change to presets requires a firmware upgrade.
@Stark9837 @3dprinting Here's the funny thing: it absolutely does, you just can't write to it. Prusa's firmware builds disable the Marlin build flag that permits this. If you use a firmware build with this enabled, you can save no problem.
The reason you can't just fix this yourself is because Prusa's firmware is signed, and without a physical mod to the board, you can't flash anything whose signature won't match.
Sounds like it is about time we fork it and make firmware and changes that it needs that the community can update their printers. #Opensource off course.
@Stark9837 @3dprinting Someone already did that: https://github.com/matthewlloyd/Llama-Mini-Firmware#readme
Unfortunately, this isn't an optimal solution because
1. It's not maintained and is quite behind now; and
2. You can't flash it anyway unless you want to physically modify the board.
However, in principle, I totally agree. Prusa's recent 'commitment' to open source feels like empty words.
Whay physical changes to the board do you need to make? Also, does it void the warranty and restrict you from returning to the original firmware?
@Stark9837 @3dprinting Yes, this will void the warranty, but won't restrict you from returning to original firmware.
The change is described here: https://help.prusa3d.com/article/flashing-custom-firmware-mini_14
"To flash your own (or a community-made) unsigned firmware, you’ll have to break the appendix on the logic board (called the Buddy board) and move the jumper in a correct position. Breaking the appendix on the Buddy board is irreversible and voids the warranty of your printer’s electronics."
Sounds a lot like those encryption boards you get. Whick I think #Bambu went crazy with, but tehirs are part of the #PCB, so it is more difficult to bypass it. I am quite surprised that not a lot of people have just removed the hardware from the #X1C and just installed #Klipper.
Probably because then you lose the beautiful touch display and wase of use of the #AMS. Although Klipper has many good color changers.
Also, do we have any news regarding the #Prusa #MMU3 at all? Like we heard some stuff and got a nice trailer for the #MK4 when it was lanuched. But we still don't know anythjng of the MMU3 and based of the MMU and MMU2, it was utter disappointments.
I think I am just going for the #EnragedRabitCarrotFeeder
@Stark9837 @LordofCandy @koz @3dprinting J. Průša mentioned it briefly in the summer update on June 15. (two paragraphs near the end)

A couple of incredibly busy weeks are behind us. I went on a tour around the North America (which was amazing!) and meanwhile, the team back at the HQ managed to wrap up a ton of things - both figuratively and literally....
@OttersDangerDen @Stark9837 @LordofCandy @koz @3dprinting I got a good pic of it. Much simpler construction, and uses a linear rail so less complex parts.
Didn't look at the filament sensor part, I may adapt the ERCF one I brought to MRRF.
@reprapryn @OttersDangerDen @LordofCandy @koz
Here, it is directly from the manual

@reprapryn @OttersDangerDen @LordofCandy @koz
Here is the repository for those interested: https://github.com/EtteGit/EnragedRabbitProject
@Stark9837 @OttersDangerDen @LordofCandy @koz @3dprinting little bit different. It's the part in the selector carriage used as an antijam sensor and presence sensor.
The head filament sense sensor you don't actually need and ERCF and others new versions aren't using it anymore. The selector sensor is necessary though.
