Guys, hopefully this is in the right forum, it's more how to physically connect these items rather than anything to do specifically with engraving.
I have an R3 Uno Arduino clone plus the protoneer v3 CNC shield, and despite numerous searches I'm none the wiser as to where I sould be connecting the output for the spindle motor, or a laser when I finally get one. The current engraver setup has a Woodpecker board that has no motor speed control, just on off control, but the output speed is too low to use with small diameter tools, and can't be changed. I'm hoping that an 'upgrade' to the arduino based board will allow me to control the spindle speed and latterly the Laser power through the software.
Neither will be high power rated (2.5w Laser) as I am not intending to do any heavy work. So, which pins are the ones I have to connect to, and what collateral hardware will I require in order to get this connected up?
Cheers
Les
