Connecting UNO R3 AVR Module / Arduino CNC Shield to TB6600 for Nema23 stepper motors

[AndyUK]

Hi Andy
Can I experiment with each pin on the shield connecting to the stepper drivers.? To find which is which. (without blowing board up) I presume pin out diagram relates to shield. I've looked everywhere for one.

Shouldn't need to experiment - everything should be relatively simple. I've drawn a basic diagram to give you an idea. Note that the colours of the wires mean nothing in my drawing, its just whatever colour I picked in paint.

• First - be careful about the power supply + and - to the driver. Make sure you get them the right way around, else bye bye driver.
• Second, Identify the pairs of wires from the stepper. It has four wires in two pairs. Use a multimeter in continuity mode to determine which wires are connected.
• Connect one pair of the motor wires to A+ and A- on the stepper driver. The other to B+ and B-.
• Next, connect DIR+ on the driver to X DIR on the shield
• Repeat for PUL/STEP + to STEP + on the CNC Shield
• Connect ENA+ to ENABLE or EN on the CNC Shield
• Connect ENA-, PUL/STEP- and DIR- to Gnd on the CNC Shield
• TEST!

Note there is no power supply connection to the CNC Shield - this is intentional. I'm expecting the CNC shield to be powered by the arduino power or USB.
