Hi Unromeo
Hi All

A mate and I have been mulling over using a Raspberry Pi and Joe's excellent software.
Actually a pair of Pi's to position an XY positioning system probably using an Arduino to automate the process of generating a rail mount. It will use a simple cutting head that "Pecks" the surface to be flattened using a small cutter head. it will only need a small motor and the cutting forces will be very light so no big deal. The completed surface will look a bit like a scraped surface. The cutter head will be mounted on the rails that will later be used in the machine being built, these will be mounted on a temporary mount.
Maybe we could collaborate?

I am planning to design the device in 3D CAD with a primary objective of Laser cutting as many of the parts as possible out of Steel.

This will keep the costs very low. I would make the mechanical s open source.

Regards
John
