With the technology used in MSLA 3D printing, the Original Prusa SL1 has a different mainboard arrangement compared to our FFF printers. It uses two boards instead of one:

• PrusA64 mainboard with A64 ARM CPU and graphics driver for both screens
• Motion controller board (MC) with drivers controlling all movements (tilt and tower)

Electronics wiring

For the exact order of the wiring and cable management, we recommend seeing the electronics section of the assembly manual.
