DIY CNC Machine

[routercnc]

Nice work Roman. My first CNC machine was plywood and it actually worked quite well and I made a lot of parts with it although in the end I found its limitations and it evolved to all metal parts. Things like relaxation of torque of the gantry screws as the wood starts to compress over time, and frame flex when pushed harder creating oval circles.

As I’m sure you know the wood stiffness is up to ~15 gPa whereas aluminium is 70 gPa and steel 210 gPa. But you have used good hardware so if you need to upgrade it will be easier. I also started with a router but the noise was terrible so upgraded to a water cooled spindle.

Hope you have fun with it !
