Hello
First of all i want to make a school project which involves a 2 axis cnc platform.
I have an Arduino Uno V3 board with an Adafruit motor shield v2.3.
All powered by an external charger 12V 1A connected to the Arduino board.
And 2 stepper motors bipolar with these specs.
http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Robotics/42BYGHM809.PDFSo, i installed the arduino board and software, which worked, connected the shield board, connected 2 steppers and tested both with the Adafruit test stepper library and both worked, also with charger set to 5V connected to Arduino board.
So now my question is, i downloaded the GcodeCNCDemo files from github, zip file, and opened the GcodeCNCDemo2Axis, connected with serial monitor, matched the transfer rate but when i try to send anything it doesnt work, the motors dont even move, at all.
Serial monitor was set to Newline, nothing worked. Config.h was also preset when i downloaded it to#define CONTROLLER AMS2
#define VERSION (2) // firmware versionso nothing changed.
Also tried increasing voltage to 9V, still doesnt work, just more heat from the boards.
Did i buy the wrong steppers?Please i would appreciate any help, thanks very much.
The only correct way to power the steppers is through the shield. trying to draw power through the arduino could damage the arduino.
if your steppers are rated 12v i’d be surprised if they move at anything less than that. What is the amperage for each stepper? Your power supply amperage has to be greater than the sum of the amperage of the stepper motors. eg, two 0.5a steppers will draw (together) 1.0a, and the board & arduino will also use a small amount – maybe 0.2a or 0.3a. That means you need a 1.3a PS to be sure your robot doesn’t “brown out” in the middle of doing a job.
Does that help?
I cannot get any of the demos to compile. The GCodecncdemo2axis just gives “error compiling” along with a large amount of, very hard to read, detail,

Error compiling.As a new user of Arduino and C++ and Java stuff I am confused beyond measure. I can get two steppers (from DVDs) to run happily using the Adafruit library but being lumbered with gobbledegook of this quality just means I cannot move forward. So any help at all would be great.
In arduino menu “tools > board” check that “arduino uno” is selected. It is probably giving errors because the wrong board is chosen.
Oh that it was that simple! No, the IDE is set up for “Arduino Uno” and “COM6 (Arduino Uno)”. BUT one of your forum members (wlr76745) mentions “#define AMS2_ADDRESS (0x60) no 61” I have no idea what that is all about as there no #define statements in the program. Could this be a problem?
Just to clarify a point I have a clone adafruit V1 motor shield. I should, therefore be using GcodeCNCDemo2AxisV1, but this program (sketch) is not in the download file, the file I am using is GcodeCNCDemo2Axis. I assume the absence of the V1 does not imply that it no longer works with the V1.
It works. At the top of the file you have to change a setting. The comments tell you what to do. Something like #define MOTHERBOARD AMS1 iirc.
Same file supports both boards.
Apparently my first post was incorrect! GcodeCNCDemo6axisV2 compiles perfectly! I didn’t try it earlier as it was a 6 axis (3 stacked boards) which I knew would not work. But why does it compile and all the others don’t?
Ok I give up! There are NO #define lines in GcodeCNCDemo2axis.ino!! Are we talking about the same program/sketch? And, by the way, I was only trying to get the sketch to verify!
Anyway I have got the whole thing working now using GRBL and some easydrive boards.
3 axis CNC device working well.
Thanks for your help.
Thanks a million! That does show the level of my stupidity! I didn’t realise that they were anything more than included library files, things which only geniuses edit, and gods write! I will have a go, later, at trying to get this to function.
I have found, in my trials and attempts with IDE and c++ that I get, fundamentally, the same error if the “void loop” segment is deleted. I fiddle with bits of code in empty files and found this error as I was trying to set up some variables in a completely blank sketch.
Anyway thanks for all your efforts and the light may just have dawned in my head.
Sorry to be a nuisance but I thought you might like to know the problem was the GRBL library. Removing it allowed me to verify and upload the code to my arduino. It doesn’t run yet but that is WIP.
Hello. I am sorry I am a bit new in this.
I have setup AFMotorShield V1 with arduino uno. i am using GcodeCNCDemo2Axis.ino. Codes are loaded and serial monitor 57600 and Newline working fine. But when i enter G00 X1 Y1 the motors don’t move at all. I checked with stepper motor test examples included in the libraries and motors worked fine in the tests.I tried member wlr76745’s suggestion #define AMS2_ADDRESS (0x60).
I loaded I2C scanner and found no I2C device in the MotorShield V1. And i couldn’t find #define Address statement on config.h and am1 files.Please help me.
