3d printed form?

For a time I was not writing any blog messages, I was still doing some stuff in the workshop. I followed the flow and bought some 3D printers, even more than one. They are useful tools for my paywork. Maybe some other day I will share info about what I use. For the current CNC I am ending there are some hollow places I could fill with epoxy granite.

I made a funnel on 3d printer

close those gaps and try to fill them with not cured epoxy granite. But as I still use not so much epoxy it was not running well. Even vibrations on the funnel did not help. So I measure those gaps, create a form and I will pour them. Then they will be installed on the machine using some small amount of clear epoxy.

In form you can see my insert made from aluminium, M5 thread. It was made in the way to avoid it being easy to tear from epoxy granite blocks and it will not rotate in holes.

It will be my first test of it. 

Show must go on

Hi, I am thinking if there will be some interest in reading posts on that blog. But recently I started looking back at my workshop and making some small jobs in it. One of the tasks is to end all started machines. Like that CNC which has some elements from epoxy granite. So let's start! One of the things I made is a table for that machine. I used recycled aluminum profiles and plywood. I used some casters to make it movable. There is some place for electronics for CNC in it.

Another thing I made is to fill the bottom of the machine with more epoxy. Its purpose is to make it heavier and less vibrating. In future there will be aluminum table on it. Added also some PE boards to avoid chips and cooling flying around.

Some work on drives is also made

And the electronic board almost connected, some small corrections needed and it will be tested.

I am old school and it still will be driven by Mach3 over the LPT connector. I bought all the elements so long ago and there is no point to scrap them and buy new stuff.
