Prusa MINI is getting Input Shaper and Pressure Advance (currently in alpha) (github.com)

Prusa MINI is getting Input Shaper and Pressure Advance! No idea when it's gonna be released as a stable version, but still quite exciting news for MINI owners (at least I was definitely waiting for Input Shaper).

Note that the firmware is in alpha, don't install it unless you know what you're doing.

If you don't know what it is:

Input Shaper is a feature designed to reduce ringing (also known as echoing or ghosting) and overshoots during printing by smoothing out the accelerations and decelerations of the printer’s movements. It works by analyzing the printer’s movements and applying a filter to the input signals to reduce the ringing effect. Thanks to faster travel speed and accelerations, it can also minimize stringing. It also enables faster printing.

Pressure Advance aims to improve the quality of printed parts by compensating for the pressure changes in the nozzle during printing. Pressure Advance together with Input Shaper enables the printing of better-looking models, reducing ringing, overshoots and issues with inconsistent filament extrusion. They also enable faster printing.

It's probably gonna be a while, but it's still great news!

Wooo, as a MINI owner I never thought I'd get this! Damn you PRUSA, foiling my plans to get a faster printer and adding value to my 2 year old purchase!

I installed this last night. I had to adjust the belts to get the Mini to home, but then everything worked and the “bonkers” benchy came out surprisingly well.

Nice! I'm too scared of alpha, I'll have to wait until at least beta.
