Since building, IвЂ™ve paired my controller board up with a Raspberry Pi running GRBLweb. I added breakout for вЂњspindle directionвЂќ and вЂњspindle enableвЂќ along side the limit header, but they are just there for possible future upgrades. This guarantees that the switches wonвЂ™t false trigger at any point. All of the buttons and limit switches are pulled up via resistor, even though Arduino apparently already does that internally. They have matched headers, so the controller can be plugged in as a вЂњwingвЂќ, or later I can add a length of wire and attach it more optimal. I designed the PCB to have a small switch panel to be cut off after milling, which has four helpful buttons: abort, start/resume, hold, and reset Arduino. I used a V-carve bit, and coated the PCB with 3-in-1 oil to both prevent PCB dust, and to improve the quality of the cuts. I actually milled the PCB for this project on the mill using the вЂњrats nestвЂќ wiring to my Arduino, just to prove out the design, and things went very smoothly. Being they only cost about $2.00 on eBay, IвЂ™m going to not worry about things beyond TTL.

I opted to not deal with a FTDI Serial->USB interface, as I had my doubts in my mill being able to cut the SMD traces small enough to host the IC, plus already had a few USB->TTL adapters laying around. First prototyped on breadboard, and then created in Eagle PCB, I have a working device I can leave attached to my mill. While all that is great, it was time to make this into a real, permanent install.

And after a lot of adjusting of Grbl settings, I was jogging around my CNC via serial terminal, yay!! Eventually, I had it wired up to a Grbl flashed Arduino Duemilanove, with a ton of loose wires between the two. I dug up all the information I could find on my particular TB6560 controller board, including schematic and documentation, but being as how these are mass produced in China with several minor changes between each clone, the documentation was both helpful and misleading at times. It accepts GCODE from the computer, and Grbl translates this into pulses, used by stepper controllers, pushing around stepper motors, while providing feedback when any limit or control switches are hit. The basics of the project are, Arduino has a USB interface, which acts like a serial port. The board has plenty of power to push the steppers around, far more than any of the smaller / cheaper solutions had to offer I think, so I wanted to try and teach this board a few new tricks, and let me interface with it using a more modern interface.Д«eing as USB was the ideal interface, and from previous searching around, Grbl seems like a great solution.

For those unfamiliar, boards like this are interfaced using an old fashioned LPT parallel port, which was initially an annoyance, but quickly became impractical and a hassle, having to use an old PC with VNC installed. IвЂ™ve had a CNC mill for a few years now, and while many homemade CNC mills use EasyDriver or Pololu, mine came with a sturdy, generic TB6560 controller board.
