Zum Modell
This design was inspired by a YouTube entry that included a CNC design which was about to go into production.
This is the second CNC design that I have produced and both aim to produce a desktop CNC which is easy to build at relatively low cost.
Note - to date this has not been built but I have a high confidence level that it will achieve the stated aims with few problems.

The design uses 50mm (3mm thick) aluminium angle and 625VV 'V' bearings for the X and Y rails. This rail and V bearing arrangement convieniently: -
---gives good separation between the V bearings
---puts the lead screw on the center line of the V bearings
---and keeps the bearing support plates (100mm*4mm aluminium) very close to the lead screw center line
Linear rails are used for the Z axis, once again, to keep the spindle/router center line as close to the X plate and V bearings as possible.
This X,Y and Z arrangement aims to minimise any lever arms which provoke unwanted movements.
