Let's build a TBot cartesian motion platform

I needed an XY motion platform for an upcoming project, and had some prior CAD work for a "T-Bot" parallel cartesian mechanism. Let's machine some parts and assemble! Not as simple as v-wheels and extrusions, but a lot more fun :) We do some milling, some drilling with carbide 2.5mm drills and full profile threadmilling.

This mechanism uses three MGN12 linear rails, GT2 steel-reinforced belt and two Anaheim Automation DC brushless servo motors. I'll be wiring this up with some encoders and an ODrive for motion control.

Apologies for the softness of the machining footage... trying out a new lens and it appears to be not very sharp :(
