With our Original Prusa i3 MK3, we have introduced a logic board called Einsy RAMBo. It works on 24V and uses Trinamic drivers for motors, allowing for super silent printing and much more.

Electronics wiring

Organizing all the cables can be a bit challenging, so we recommend you take your time. If there are any issues with your printer's wiring, they will be most likely discovered by the Selftest failed (MK3/MK3S/MK3S+) or when running the initial Wizard. For more information about the cable management, we recommend checking Electronics assembly of the assembly manual.

Note, that the filament sensor is called the IR sensor on the MK3S. The position of its cable is still the same.

Did you know, that...?
The RAMBo board is designed and built to sustain considerable heat. It does not need any cooling even if the printer is in an enclosure. 
However, keep in mind that a temperature close to 100 °C can cause damage. If the printer measures more than 100 °C at any point, it will trigger an Ambient Maxtemp Error.
