We’ve been working on addressing the random CPU changes that Creality pushed out to its customers who purchased printers recently. We posted a few days ago about the CPU swaps happening and promised to work on a firmware update, you can read that post here. We have a build that is passing and works on the 512K CPU parts but we need someone to contact us who’s willing to test the firmware out on their Creality board that has the STM32F103 RCT6 CPU on it.

If you have one of the affected boards (this is confirmed to be on the 4.2.2 and 4.2.7 boards) please Contact Us and the team will get your request over to Tim and he’ll work with you to get the firmware to test with. We were expecting this to take much longer but it looks like it should be good to go once we confirm it on an actual board with that CPU.
