It can be hard to find the plans for this machine online. Here’s some help!

You’ll assemble most of it by just looking at the photos.

The manual I got with the latest one I ordered was pretty good.

The details page has a link to this dropbox:

Which has drivers, the manual, etc.

For the GRBL sender I have had good success with GRBL Panel which didn’t have as many features as others, but WORKED. https://github.com/gerritv/Grbl-Panel

One option I added for the little CNC was a proper collet:

This makes it easy to use better tools. I was using a standard 1/4” v-carving router bit, for instance. I found that the hole in the adapter that is supposed to slide over the 5mm motor shaft was just a bit small. I reamed it out with a 5mm ream, and that worked great. For the first one, I had to shove it onto the motor shaft with a vise – which worked, but I’ll never get it off!

Finally, one change I made was to use better nuts and bolts. The screws that come with the thing are soft – like aluminum, and have Phillips heads, which I hate. Proper metric cap screws are much better. Sorry for .ca links.

Wow, what a busy weekend we had, cranking out puck after puck for two days. I had purchased about 150 pucks before the faire, but had to puchase another 100 pucks Sunday morning on the way to the Faire.

The puck mill had created about 15-20 pucks before the faire – test pucks as I was calibrating the X and Y axis, and setting the Z height. But, from the second the Faire started, until it ended, we were continually carving names into pucks. The machine literally ran non-stop – as quickly as we could swap new pucks into the machine, it would start carving again.

So, over two days, we created 300 pucks in total – that’s 300 puck designs, and 300 toolpath G-Code files, and then sending them all to the Planet-cnc controller to create the pucks. Our copy of Vectric V-Carve Pro was really put to the test! [Read more…]
