#Flashing grbl to an arduino for mac how to

The triple head was really easy to set up on a mac and is a very powerful device. I could not find a cable to suit so unfortunately I had to solder directly to the ISCP headers (not pretty). One thing that sparkfun didnt explain is that you must disable auto reset on serial connection. I found the wiring diagram from Sparkfun here and the picture below is my version of the wiring. Open up the Arduino IDE then go to File - examples - Arduino ISP then upload the sketch to the Arduino. This is a very simple task as it is all built into the Arduino IDE. I thought I would document my process in case anyone else finds it useful.

#Flashing grbl to an arduino for mac how to

There are already several sites with information on how to do this but I found I needed bits from all my sources to get the job done. I have never done this before so I let the Arduino rest for the the remainder of the training with a mind to try it as soon as possible. Grbl seemed like a very simple solution but the main hurdle when it comes to implementing it is that you need to use avrdude to flash it to the Arduino you cant just send it via usb direct to the Arduino. I had no success over the three days of training but I did find Grbl though I didnt have the kit to test it. I really struggled, probably partly due to my lack of understanding when it comes to g-code. I also tried a few other interpreters with varying success: teapot, rsteppercontrol and arduino-gcode-interpreter-new. The home site for the Contraptor project has a lot of useful information, it was there I came across Grbl.

There is also another CNC project called Contraptor which utilises the Arduino at its heart. I was 100 sure the solution to this problem was the trusty Arduino. Flashing Grbl To An Arduino Mac Does Not.
