Using Arduino UNO with GRBL connected to a WANTAI MOTOR DQ860MA Driver 7.8A phase current. When I power up the driver with 24 volts the motor goes to standstill lock. When I send steps to the driver using the Universal GCode Sender I the stepper does not rotate.
I have tested the Arduino UNO with GRBL and Universal GCode Sender using Pololu A4988 Stepper Motor Driver and SparkFun Easy Driver (with smaller motors) and both work.
I have the following setup:
Arduino UNO with GRBL pin 2 to PUL - , pin 5 to DIR - and pin 8 to ENBL -. PUL +, DIR + and ENBL + and tied to 5v on the Arduino board. Ground on the Arduino board is tied to 24v ground.
The following are the settings in Universal GCode Sender:
$100=3.333 (x, step/mm)
$101=3.333 (y, step/mm)
$102=56.693 (z, step/mm)
$110=7315.000 (x max rate, mm/min)
$111=7315.000 (y max rate, mm/min)
$112=600.000 (z max rate, mm/min)
$120=3500.000 (x accel, mm/sec^2)
$121=3500.000 (y accel, mm/sec^2)
$122=100.000 (z accel, mm/sec^2)
I have tried various J2 jumper settings, inverted PUL - , DIR - and ENBL - to ground and PUL + , DIR + and ENBL + To pins 2, 5, 8 respectfully.
I plan to use these drivers with SIGMA 20-4247TD200-F1.3 stepper motors (200 step, 540 oz-in @ 50 sps, 635 oz-in holding, 5.0 Amp phase current) on a large CNC Wood Router I am building (6' x 6' x 2').
Any help you could offer would be greatly appreciated.
