@aventgps and anyone who can help. I am building a 3 axis CNC router and was very happy to find this forum post about controlling a CNC with a ArduinoMega! I have my stepper motors and I bought some drivers for them, I thought about making my own but I lack of patience got the better of me and I bought some. I have done some preliminary tests and successfully got the arduino running one stepper using the stepper library in the arduino IDE.
Next step is where I am struggling, I found the reprap site also but didn't find much on it about the arduino setup (anyone have a good link?) I uploaded a modified reprap sketch for the stepper control with the parameters for my steppers. Where I am stuck is then implementing the Gcode control to the arduino. What do you use for this? There are a lot of options out there some people use pearl scripts, ReplicatorG or there is the reprap software. I am trying to use a mac to control it but I could use linux if needs be. I have been trying to use ReplicatorG and it is promising but it says there is no serial interface connected, I can't believe it would not work over USB, I am assuming you have it working with usb? Is anyone else using this or could someone describe there software setup along with the arduino sketch and Gcode control?
Another area I am not sure about is will I need to modify the code for my drivers a bit more. The drivers worked for the stepper library with the pulse control but the drivers also have a two pin direction control, are there pins assigned for this in the reprap stepper control?
Any help would be great, thanks!
