Motors:
1) Applied Motion Tech 5023-267 (DC9.0v, 470 mA, 19 ohm, 200 steps/rev)
8-wire stepper using 4 wires, but works normally when attached alone

2) Mitsumi m42sp-6tg (DC12v, 400 mA, 5 ohm, 48 step/rev)
4-wire stepper – works fine on any axis when used alone

When I try to connect a second stepper, neither stepper will work.. they make noise, but don’t run forward or backward (seem to jerk back and forth like they are wired wrong). If I unplug one motor, then the remaining motor works fine, but with 2 motors (ex. one on x-axis and one on y-axis) then neither motor on either axis works. I am only trying to run one motor at a time.

Hoping it’s a power supply problem, but given the rated amps I should have some power left in reserve even if the other motor is “holding”…

EN/GND
X.STEP/X.DIR
Y.STEP/Y.DIR
Z.STEP/Z.DIR
A.STEP/A.DIR
5V/GND

as used?

The goal you are after will be hard for GRBL cause it barely fit onto Arduino Uno anymore. However you can always a Raspberry by that talks with GRBL and then you can save
the files on the Raspberry and send it line for line to GRBL. Uneversal G-Code runner should be able to load a file and send it for you to GRBL

I want to share my question about your lib & shield, is there any forum to start thread

My question is

I want to send data file to SD card and command to the shield via Wifi or wireless shield not the USB or cable ,any help or guide really is appreciated

Best Regards

They said to use Z limiter with COM and NC wiring i had uploaded HEX file from Droplit github with this confs.

**** Connected to COM7 @ 9600 baud ****

ok

i don’t find ground (sorry I feel like an idiot to be asking these questions)

I did this https://drive.google.com/file/d/0B7QBQEcpOvlaTlEtTzhwbU1hMUVwLXQxQ3I5WHhNZkRGQ01n/view?usp=sharing

It right ?

I try Ground near Z+ and no signal if i pull buttom. now i try this. my board it V3.0

Your end stop pins in V3 use just signal and grd like a ramps 1.4 ? Z+ side are signal and other pin signal ?

Cheers!

Connect an end stop to it that is always open.(Like a button)

??

Or i using END Stop to limiter like in fdm printer ?

Sorry but i never work with GBRL shields, just with RUMBA boards. Its my 1st DLP printer

cheers!
