Hi All Quick question I have been looking up the correct wiring to connect the TB6600 Drivers to a Mega for GBRL control, however I am getting a conflict in how to wire these up. Some say connect Dir- and Pul- to Ground and Connect Dir+ and Pul+ to Mega Output Pins according to GBRL and others are connecting Dir+ and Pul+ to 5v on the Mega and Dir- and Pul- to Mega Output Pins according to GBRL Which is it? Cheers MM
Actually, either will work since the inputs of the TB6600 use opto-isolators which are essentially LEDs and the two outputs go between +5V and 0V (gnd). Though, you may have to swap your motor cables around to get the correct direction (or change it in GRBL). This is true for any arduino board, btw. I'm using TB6600s and wire the - inputs to gnd with my Uno Shield (my own design).
