I bought this last week and managed to get it up and running on my Voron 2.4R2
I can confirm that these boards have issues. I am also having an undervoltage issue seen by others relating to the TMC2240.
I tried chaning a number of settings seen here:
https://github.com/Esoterical/voron_canbus/blob/main/toolhead_flashing/common_hardware/BigTreeTech%20SB2209%20and%20SB2240/SB2240%20Stepper%20Configuration%20and%20Undervoltage.md
including stepping down the current to the extruder to .55 instead of .65 which is the reccommened stock.
Im pretty upset with BTT on this I spent nearly 5 hours unwiring then rewiring my printer to install this.
Made my printer virtually unusable. I will be replacing it with another canbus setup.
I have used West3D for a number of parts for my voron and wish this site only the best, but you should pull this from your site. It is not worth the time or money.
