Printed the XY ends

Everything fits (well almost):

- The retainer must be some 2mm deeper for the M8 bolts to not to stick out into the slider.
- The stepper mounting plate has a round protrusion that I forgot about, need to make a corresponding hole for the motor to sit tightly.

Otherwise, it is all tight and rigid, everything fits precisely.

Pouring the epoxy and next steps

Mixing and pouring epoxy is simple. But there is one but. Epoxy may seem viscous, but it will go through the smallest of cracks.

So after I poured it, I had a fun session where I ran around with a hot glue gun (thanks whomever necessary for that invention) and plugged the links. Finally, it slowed enough that I could let it dry hoping that something will remain inside. Here it is:



The next life saver was the Fein Multimaster.

1. The spools of epoxy, which I tried to sponge out with wads of paper became a mess of semi-hard papier mache. Didn't succeed to tear them off, so I just cut them out.
2. The edges of the surface weren't flat because of the surface tension. The multitool made an easy task of sawing them off at 45 degrees.

And here is the end product:



Added legs (see the remains of silicon, glued to the frame with epoxy) :( .



The next step is assembling the linear guides. The material is already here.

Straightening the CNC plate - preparation

The metal frame is bent, and very hard to straighten back. So the idea is to pour a layer of epoxy on it to create a flat surface.
