This board connects to an Arduino UNO
or Arduino Mega
in order to control a cnc machine.
A cnc machine is a tool (a drill, milling machine, laser, etc.) that moves along the axes driven by a computer-controlled motor. CNC machines improve productivity as well as precision in product manufacturing.
The board can control up to four axes by means of drivers type A4988
, either to duplicate one of the axis or to employ a secondary motor.
It allows up to 6 limit switches (for the minimum and maximum position of each axis) and it features a terminal with an input voltage of 123-36V.
You can use an open source firmware called “GRBL” and a software named “G-code Sender” for operating the cnc machine.
