My 3d printer has been ressurected! And so I immediately ordered it to start printing!
I have de greased the steel plates and sprayed a light coat of black paint on the outer sides, the sides I will not glue magnets to. The curve on the smaller parts is hard to spot so the idea behind the paint is to make it easy to avoid gluing the magnets to the wrong side.
I plan to start gluing magnets tomorrow. (the grey plastic parts are my glue jigs to help fit magnets at every odd hole. Then I have smaller jigs to help fit magnets in between the then glued magnets.
And meanwhile, I have test printed an edge part to test the fit. And it fits nice and snug. With a small dash of superglue this should fit together perfectly. I just need enough glue to hold it together before assembly. When the final assembly is done then the 3 screws will hold it toghether and provide the strength.
In my previous iteration I used small M3x3 mm threaded inserts but if I tightened the screw too much they came loose inside the plastic part. That would then be a recipe for disaster since it would probably rattle. This iteration with a little glue and then every other hole with a plastic dowel pin to hold it in place is a much easier and more reliable solution.
If it continues to progress as nicely and fast as this, then I might have the two test drivers with 4 and 6 rows of membrane traces respectively done by next weekend and ready for measurements.
