This combination should work without any problems.
Just to check your hardware is OK, do the following:
- Use the attached GRBL configuration, upload it to the GRBL controller and check each setting after uploading. This configuration works for a TB6560 / GRBL combinations
- Remove all connections from the driver
- Connect the arduino +5V to TB6560 CLK+
- Connect the arduino PIN2 (Step pulse X-axis) to TB6560 CLK-
- Connect the power supply GND to the TB6560 GND
- Connect the power supply Output (probably 24 V) to the TB6560 24V
- Set all TB6560 dip-switches to OFF
- Set all TB6560 dip-switch SW1 to on (1.6A run current)
- Disconnect the stepper motor axis
- Try to turn it by hand
- Take one of the 4 stepper wires
- Connect it to one of the other 3 wires
- Turn the stepper motor axis. If it is harder to turn, these 2 wires form a set (coil), if not try one of the other two.
- Connect the two stepper wires found to the A+ and A- of the TB6560
- Connect the other two stepper wires to the B+ and B- of the TB6560
Now use Gcode sender to jog at a feed rate of 1 mm/min. You should see the pulse led on the TB6560 board blink and the stepper should turn slowly.
I used UGS 2.0 for testing, but any version will do.
Let me know if this works.
