Hi,
4 wires of stepper I did check with multi meter from driver interface getting continuity.
As I thought you mean adruino dir+pin not contact with Dir+ tb6600 driver ? I did try and check wires all connected. youmean I need check once motor 4 wires to driver from this one is not contact upto driver?
Thankyou for reply
Can you one more help please If we have new Adruino should we need to add GRBL library in Adruino software I have doubt maybe steppers not moving both directions I had checked all wiring is correct or maybe the TB6600 drivers are not working.
