My aim is to build a desktop router utilising 43 mm Kress spindle, it will mainly be used for cutting wood and aluminium plate.

It will be a hobby machine but I would still like it reliable and accurate as I intend to use it mainly for cutting birch ply for RC model aeroplanes and would like them to 'click' together. I will also use it for all the other fun DIY projects.

I don't have a workshop, my only tool is a Stepcraft D600 and 3d Printer, so the design has been tweaked so I can machine most of the parts myself. The only two pieces I will have to subcontract are the top and bottom Z axis plates as I cannot get the vertical accuracy.

I am trying to balance the complexity / weight / accuracy

All the axis are direct drive so there are no pulleys etc

The design utilises :-
1000 mm 1605 C5 twin ballscrews on the Y axis
750 mm 1605 C5 ballscrew for the X axis
200 mm 1605 C7 ballscrew for the z axis
NEMA 23 74 mm stepper motors on all axis
CW5054 stepper drivers
400 Watt PSU
KK01 Breakout board
All the extrusion is standard off the shelf profiles (Oozenest and KJN)
HGR15 linear rails and HiWin carriages on all axis
Low profile t Slot plate (vacuum tables)

Cutting Area should be 850 mm x 550 mm with 70 mm vertical clearance
