First Proper CNC Router

[diycnc]

So after 6 months my CAD models are starting to turn into a CNC!... Slowly....

The design has changed a bit, but the concept is mostly the same.



I went with aluminium flat bar rather then cast plate in the end. Very quickly learned that was a bad idea! Flat bar is very far from flat!
Managed to get everything moving freely so far despite the not flat bar using plenty of shims to level things up. First project when this thing is up an running will be new cast aluminium plates.

So far I have the gantry carriage and ball screw all made and assembled. Made my own ball screw end supports from 50x50 aluminium bar with angular contact bearings, and bored out and threaded the HTD pulley to replace the lock screw. Everything moves freely and feels rock solid, so very happy with the result.

Sick of drilling and tapping holes now.
