With the Chinese companies trying to keep costs low, most of them are swapping out name brand CPUs from vendors like STM32 to others that are not supported by firmware that we all commonly use. We put out the firmware for the community to make 3D printers better as well as make using our products […]
More CPU swaps to make things harder for everyone Those of you who bought Ender 3 S1 printers or replacement boards may have noticed that some of them are coming with STM32F401 CPUs on them instead of the STM32F103 CPUs that they originally shipped with. The good news is that Creality did release the source […]
Back in August BigTreeTech was sending out some boards with the GD32 CPUs that are STM32 clones on them. These chips had odd compatibility issues with Marlin and other firmware that required workarounds and patches to code to get them running. These CPUs are not STM32 licensed cores and running standard STM32 code on them […]
CPUs Swapped Out In our Discord server a user was working on their machine and was having issues with the firmware. They posted a picture of the board and it revealed a lesser STM32 part number on that board. The 4.2.2 and 4.2.7 boards have all shipped with the STM32F103 RET6 CPUs since release. Now […]
We’re proud to announce that the 1st batch of boards that were made are ready to be moved into full scale production. We’ve completed over 200 hours of printing on the retail board version as well as 1000+ hours on the prototype. All firmware is working, thermal testing passed, and load testing passed. We are […]
