Some progress here. I built a power feed to have more consistent feed rates and improve the surface finish. It looks like it works. I have a set of micrometers, still working on the accuracy. Not having children screaming around might help on that aspect.
In the process I snapped my first drill bit: I was not drilling anything, just testing the software for the Arduino that controls the power feed. I forgot a 7mm drill bit in the chuck and it was snapped by the vise like a cookie. It was a bit scary, mostly because I was not aware of any risk as the spindle was not rotating.
I am now quite happy with the controller as it preserve knowledge of the absolute position of the table so it prevent to hit the end of the run.
The old and a new block
DIY motor mount
Controller prototype (he needs a proper box)
