Robin's smt Pick and Place build

[Robin Hewitt]

Few weeks ago, I converted engraver to have some fun with placing SMD parts:

Blimey Sigi, I never thought that QFP would go down in place. Did you stencil the paste mask?

I had a bit of a software blip that slowed me down but I'm back cutting metal (and seaching for 2mm screws to hold a microswitch :whistling:).

This is the start of the Z axis and rotation. It lifts amd lowers by cam action with another NEMA17 for the rotation. Had to use a linear slide for the up down because it descends under gravity and I can't risk it sticking.

The lifting cam has to run on steel because aluminium would dent.

I sank the linear slide in to the 8mm plate so that it can't come apart now the tabs are off

AutoCAD side view to show how it goes together. Plates in cyan, linear slide in green.

Next the 3/4" pitch nut mountings and the component rotation motor plate.
