Summary
MKS Gen is a feature rich all-in-one electronics solution for Reprap and other CNC devices.
It features an onboard ATmega2560. Its five motor outputs are powered by Pololu pin compatible stepper drivers.
The board features a developer friendly expansion port supporting giving access the same as Ramps1.4.
MKS Gen is designed to be flexible in the user's power source availability, allowing any power supply from 12V-24V.
Safety Tip
Caution Once you start putting electricity into your RepRap - even at just 12 volts - you have to take basic, common sense precautions to avoid fires. |
