After successful construction of a 3D printer,
I began studying to build my milling machine and

These source files have not been fully tested, but if people want tested parts in 3D printing and lift their criticisms are welcome.

VSlotWheelSpacing20x40=59.60;
I put a calculated value but it must be validated with a printed test.
