    ok we have GRBL! I'm not sure if you updated the files or not, but rather than the standard zip, I tried the Net Beans project zip and It is working!

    thanks! If the ino you're running is working then perhaps it'll do the job.

    Those settings I manually configured in the Arduino IDE under the "config.h"Still haven't got the grbl settings to show by simply typing$$. The settings tab in grbl controller may be just the ticket.Ill try a few things when back home tonight and let ya know.

    OK testing tonight ....no matter what baud rate I use "$$" or "$" returns "error: bad number format" and "?" returns "error: expected command letter"Its like the grbl system commands just will not work. I even re-downloaded the zip file and tried a fresh ino file.I tried directly in the serial monitor at different baud rates, I tried both teleporter and gcode controller at different baud rates.The G codes tx and rx just fine... any ideas?

    Thanks! I haven't installed limit switches yet. Those commands will definitely help.Thus far I've simply moved the x and y axis from one end to the other. So far I have about x12000 and y4500 work area( still not sure if grbl is seeing these requests as mm or step)I did set the mm per step, and steps per revolution.(200 steps per rev, using 18 threads per 254mm or 1inch) I need to check out grbl controller currently I'm working with gcode teleporter.

    I may also need to simply use a plain serial connection to see if the $ commands issue isnt in the interface software im using

    Alrighty! Motors etc. are up and steppin'! Most standard g codes are operating perfectly, but the grbl system commands aren't working( like "Home" and "Zero")These are the commands that in grbl usually start with a "$"...is that normal? (e.g. they were not programmed due to available space) or am I still missing something?Id also like to add an extruder capability which will require an additional stepper, and in the future I might like to add additional axises...

    Thanks Vasiliuc! Just wanted to clarify those few points. Im still getting those duplicates and will continue working on clearing those. I may need to do a complete reinstall on my CnC computer with upgraded IDE( currently running 1.06 and have had other issues with the serial coms with ot)her sketches). Still building on the Hardware portions and will be back to testing motors etc. as soon as I get my Power supply.I'll keep you posted.

    Vasiliuc, Excellent work on interfacing this shield to GRBL.Could the eeprom errors below mentioned by Gurpreet may be that the Arduino wasn't flashed with the GRBL hex file.Could you go through a bit on exactly the process you used to get your hex file, libraries and sketch all loaded correctly and communicating, or did you even have to load the GRBL hex?Again thanks for your work on this, the stackable configuation of the adafruit would allow a person to do tons of stuff just using simple gcode.

    Also, what versions of the Arduino are you using and which IDE revision?
