I ran into a challenge recently where I didn’t have enough spare pins that could PWM on ramps. I want to add LEDs for lighting and to signify certain events. To work around the issue, I decided to make an i2c-rgb led adapter. I2C lets me have up to 127 devices. I plan to makeContinue Reading

In the first part, I created took the circuit and created the gcode that the machine would use.  This part will show it actually running on the machine. First, the overall setup that I’m using.  I’m using a Taig CNC Mill with a vacuum table to hold down the PCB. The first thing we doContinue Reading

So you’ve see my milling examples in previous posts.  I’ve been working on getting the toolchain right, getting the hardware right, etc, etc.  I’m going to walk you through the steps on milling a PCB.  For his example, I downloaded a RBBB arduino from this instructable. You can see the board pulled up in myContinue Reading
