BTT Scylla Recall - 12VDC Relay

[PFarm]

According to the discussion in Discord Biqu is recalling BTT Scylla V1.0 motherboards that were shipped with the 12VDC relay. If you have the 12VDC relay contact your vendor for a replacement board. The replacement board will have a 5VDC relay.

Many thanks for the info!

The new replacement Scylla board came in today. I waited for the new board to make wiring and hardware changes. Removing the 350w 24v power and replacing it with a 24v 60w DIN mount PS, since the stepper motors are connected to a 36v PS, only 30w is needed to run the board, but the 60w I purchased was cheaper than the 30w. Also changing out the 12v PS that supplies power to case fans, water pump and rad fans to a DIN mount PS. I'll be relocating the Scylla to where the 24v PS was and shortening the wires. I'll be adding UK2.5 DIN terminal strips as well.

Got the onboard 12V relay swapped out with the proper 5V on the original Scylla board. It was an easy swap, five desolder points and the relay out.
