got debian 11 successfully flashed onto my #sonicPad and set up with klipper, moonraker, and mainsail. was able to use it to tune the resonance ringing via the accelerometer and got significantly less x/y ringing after applying the analyzer's recommendations. despite being a pain in the ass to actually flash it onto the pad (I had to resort to a windows machine - egads) it seems a lot nicer this way than trying to get the stock firmware to work this nicely with a custom printer setup.
tomorrow I'll get the calipers out and dial in the extrusion a bit closer to reality and get pressure advance set up. #3dPrinting
