I'm new here and been reading a lot about arduino. I'm building a 3 axis CNC router and plan to use the mega 2560.
I saw on youtube the 2560 is used with a 3/4 axis stepper motor driver based on the tb6600 and want to know how you connect the arduino to it. I see on the video some wires are run from the driver printer port DB25 to the mega2560 and the arduino connects to the pc via usb.
Anyone knows how this is done? Been searching online but can't find it.
I won't be using the arduino motor shield coz I need more than 2A to run the steppers.
I need help. Thanks in advance!
