MKS RUMBA32 is modified in Aus3D RUMBA32 version and a powerful 32-bit 3D printer control board with STM32F446VET6 , The main frequency is 180MHZ. Support Marlin2.0 , support MKS LCD12864B/MINI12864/2004/12864, support MKS TFT24/28/32/35/70 Screens. The motherboard integrates 6 AXIS interface, integrates SPI / UART interface…
Idea number one : Create RUMBA32++
If we have Tmc2130 SPI , each ' step + dir ' pins are unused , and it's 12 pins !!!!! LOST !!!!
Create a new port with :
12 pins : 6 x (step + dir )
3 pins of the SPI bus ' to expand with some stepmotors , each motor need 1 pin + SPI bus )
With these pins , we can add , led , servomotor, new stepmotor , alarm , fire alarm , sms alarm and more
Idea number two :
Add fuses onboard to protect short circuits of the heater or bed
Idea number three :
Increase the size of the connectors , of heaters or power , or bed , because TOO LITTLE
Idea number four :
More power on the 5v , because servomotors cannot be drived directly by the board
Thks
Now with TMC2130 , we have 12 pins free , for 12 motors , for led , for robotics , for communication with GSM alarm
