Hi, I hope this is in the right place.
I’ve recently been playing around with GRBL and Arduino and a Shield and have been having problems getting a stepper motor to turn.
My Setup is this, Arduino MEGA hooked up to a GRBLDuino Shield
I’ve got a PWR supply of 19.1 Volts (190 Watt Max)
Testing the driver revealed the following
19.1V - VMOT
5V - FAULT, SLEEP, RESET, ENABLE
0V - STEP - DIR
While sending GCode
19.1V - VMOT
5V - FAULT, SLEEP, RESET, STEP, DIR, ENABLE
While I don’t think it’s the Driver’s issue, I just want confirmation on a few things:
The Enable pin must be pulled LOW in order for the motor to turn. (Which I haven’t been able to simulate yet)
The Step and Dir pins are correctly operating with the above situation.
Thanks
