Creality Ender 3 V2 (Klipper) (Moderately modified)

Selling a modified Ender 3 V2 due to time constraints. Currently the printer is setup with Klipper and the control board is BTT SKR Mini E3 V3. The companion SBC is a Rasbperry Pi 4. The creality silent motherboard is also provided, which also has Klipper setup in it. I have printed with speed 100-130mm/s with 3500 accelaration reliably with Klipper. I will provide config for both MCU and slicer profile.

List of mods:

Disclaimer: This is, obviously, a DIY printer and ideally you're experienced with this and you'd know what your buying. I have setup Klipper very recently and I have been done a lot of tweaks around it and a config file is already prepared with many options covered. However, there're still a thing or two needs to be improved (and tweaked) and I do not have time for these anymore. They are expected to be carried on, whoever is buying it.
