Desktop CNC – Work In Progress

To make my projects smaller and more durable, it would be better to make custom PCB’s rather than jamming a wad of wires into already small cases. To make this possible, I’ve made a desktop CNC. To keep the costs down, it will be made using mostly surplus parts. To cut back on costs further the sides and 3D printed parts where redesigned to fit 8mm smooth rods, rather than 12mm, which are considerably more expensive and harder to find. There are many revisions of the CNC design I chose and I had to piece together parts from 2 or Continue Reading →

MP3DP v2

After rebuilding the center of my MPCNC, buying another router and converting it to dual axis independent motors, I wanted to test it’s alignment by making the MP3DP v2 – another V1 Engineering project. Some of the core components came from my aging Prusa i2, which had significantly less build volume (20x20x7) There was a small issue with the parts being CNC’d using the new firmware. rounded corners seemed to be randomly hit and miss – I found out that the firmware didn’t cut arc’s very well, so they had to be removed from the g-code Core components removed: stepper Continue Reading →

Virtual Pinball Machine

Virtual pinball tables consist of the same basic elements as regular pinball machines with a few replacements; The playfield and backglass are replaced with monitors and controlled by a PC. The buttons (and sometimes the plunger) are replaced by buttons and a game controller or keyboard emulator. In more advanced tables the LED dot matrix display replaced with a compatible replacement or a 3rd monitor. This previous project was the perfect test bed to see if the PC I was planning on using was good enough to run the games smoothly. The first test run was running Future Pinball with a Continue Reading →

Bartop Arcade

I’ve wanted to build a bartop MAME cabinet for a while, my first attempts last year led to 4 failed CNC jobs, infact the first side panel I did for this project ended up the same way (top left): The Z axis fails; instead of going up, it skips the instructions to raise, and then drills down into the wood, going further and further until either the bit snaps or I turn it off (to prevent fire). This second attempt was successful – I worked out that if I don’t put the front and top panels on the CNC machine Continue Reading →

Mostly Printed CNC (MP-CNC)

Having a CNC machine to cut panels for projects has been a wish for a while. Then I found this awesome project: Mostly Printed CNC (www.vicious1.com). As the name says, most parts are 3D printed and the non-printed parts are easily accessible. The controller is a RAMPs 1.4 board with Arduino Mega, easy to find cheap online. I used the Marlin firmware because it’s the same as both my 3D printers. After destroying my Mendel i2 trying a new printing surface I had spent many hours printing the parts on my Solidoodle2 with a printing volume 6″ x 6″ x Continue Reading →
