I'm Actually using my Homemade Solar Powered Brushless Motor driven Milling Machine (that's a mouthful) to produce a new door cassette cam.
Here I show the whole process of copying a part, from initial CAD drawing, through post processing (generating G-Code), writing this to the mill controller, then machining the part out.
The part is a door handle spring cassette that is under a fair amount of stress when operated, therefore I chose to use an old thermal viscous fan spanner that is made from pressed, hardened tempered steel. This one shouldn't fail in a hurry.
Milling this, the YG "ONLY ONE" end mill makes light work of churning through this material and will machine a lot deeper into the part, although I needed to keep the noise down.
Details for the cutter are: - YG PM60, GYF96030, 4F, Y-Coating, Short, 3x6x8x52
The milling machine is an Axminster Sieg X1 and still has the Acetal gears that are over 10 Years Old. These will soon be replaced with an ODrive brushless motor and toothed HTD belt, which will make it a lot quieter and allow me to carry out some machine tapping.
Solar Power is where it's at......
Yes this machine is completely running off Solar Energy, where I have a 50W Solar Panel in the garden that charges a bank of batteries equaling 75Ah. The 240v brushed motor is powered via a 1000W pure sine wave inverter and the Brushless X & Y Axis motors run from 12v dc; where the machine will run for around 8 hours on a full solar charge.
I have more home solar projects that I am working on, so please check out my website here: -

Controlling the X & Y Axis motors is an ODrive motor controller that is itself receiving commands from an Arduino Mega 2560 in standard Arduino C code. You can see the latest code here: -
