The described kit has a small board to use in stead of the A4988 drivers. The cable on this small board is used to connect the TB6600 drivers.A4988 – I do have 4 of these, but am I correct to assume that I do not need to have these on the shield since I have the motor drivers?
I have tried this some time ago and it worked.
check these at a slow rate 10 mm / min:The stepper motor did get warm and sounded like it was humming, but it never rotated at all.
- when nothing is moving, the steppers should be movable by hand.
- when you jog, the steppers should rotate (good) or be locked (not movable by hand, at least the enable pin is connected ok)
Start by connecting 1 stepper and 1 driver
The TB6600 drivers need (for starting) only the power supply, +5V signal (from Arduino) and the pulse (step) signal from the small board. Try this first. The stepper should rotate when you jog.
Connect the direction signal from the small board to the TB6600. The stepper should rotate in both directions depending on the jogging direction
Connect the enable signal from the small board to the TB600. If the stepper isn't rotating any more, invert the enable pin ($4 setting grbl).
let me know it is working
