MicroMill CNC RetroFit Project Files!

thingiverse

This post houses all of the related STL and product links used to retrofit a small Chinese micro-mill for CNC functionality. You can view more about the base Micro-Mill here: http://diy3dtech.com/micromill-resource-page/ To attach motor mounts to all three axes, 3-inch long #8-32 bolts were used and the mill was taped to receive them. It's likely that a metric substitution exists; however, the length must be maintained. To attach motors to lead screws, 3mmx5mm Brass Shaft Coupling (https://amzn.to/2VLJvfZ) was utilized, along with drilling out and tapping the 3mm side to 4mm which screwed onto the shaft while the 5mm attaches to the motors. It's worth noting that this setup works but may not be ideal due to over-rigidity; it's recommended to reevaluate this approach in future projects. It's also essential to follow DIY3Dtech on Instagram (http://instagram.diy3dtech.com) as short videos on designs and operations will be posted ahead of longer running YouTube build videos.
