This is the test for 32bit stm32 based 3d printer main board working with CAN bus module. The Pandapi V2.9 is working in standalone mode which have no raspberry pi attached.
It works well with BLTOUCH,hotend Heat,runout sensor,FANs, except the extruder motor which have sync problem between stm32 and CAN module but no problem with ESP32 based main board.
