European group buy of jackpot boards
The SKR Pro is directly supported (SKR Pro v1.2) with TMC2209 drivers. The SKR 1.4 Turbo has been made to work, but is not directly supported. The SKR 1.4 (not Turbo) has “community supported” firmware.
SKR Board naming is a bit deceptive. Higher numbers do not always mean newer. The SKR 1.4 is a different board than the SKR 1.4 Turbo, and the SKR 1.2 Pro is a newer board than the SKR 1.4 (I think about the same release time as the 1.4 Turbo.) IMO, the number should come after the designation so that it is a little more clear that the different boards are different lines. Each requires a different compile of the firmware.
