Re: soundproofing enclosures?

I've done some research into it and I'm not sure I'm convinced that Green Glue is much better than two sheets of drywall stuck together with silicone caulk or some other flexible adhesive, or even just attached next to each other. The main thing doing the dampening is the mass of the drywall.

Re: Best bits to cut wood with Dremel

Slowly, dangerously and generally inaccurately. I would need more specifics to answer in more detail. I've been “cutting wood” for 10–15 years and I've never used a dremel for anything other than carving wood and even then there are better , more powerful tools. Look into a jigsaw, circular saw or ...

Re: Grbl / SuperPID / Shapeoko 3

The unfortunate reality of controlling the spindle this way is we only have 255 possible settings with each jump being about 117RPM. So no matter what value you send to grbl in terms of spindle RPM you will only get within about +/- 59RPM of the value you set. Besides the aesthetic issue of setting...

Re: Stock Purchase

My local hardwood shop sells baltic birch plywood in 5'x5' sheets. For a couple of bucks extra, they cut them into 15"x5' strips with a big panel saw, which I cut into 15" squares on my miter saw back home.

Re: Did you upgrade ? I want to buy your old extrusions.

If I ever upgrade (unlikely, as it would involve also upgrading my garage) I'd like to make the extrusions into a beefy delta printer.

Re: Compensate the tool radius G43

Tool radius compensation is G40/G41/G42. G43 is tool length compensation. Of these, the only command supported by Grbl is G40, which turns tool radius compensation off. Generally speaking, Grbl avoids supporting commands that are primarily used to write or tweak G-code files by hand, like variables,...

Re: What the bleep is going on?

A little bit of slop in the logo test is expected, because you likely didn't do a perfectly rigid job of mounting the pen, and the pen itself is flexible. This can cause strokes in one direction to deflect the pen one way, and strokes in the other direction to do the reverse. As far as the wood test...

Re: Wooden GameCube

Here's a guy who made a GameCube case out of a cardboard box: http://gameboxgc.blogspot.com/2012/06/c ... -case.html

So yeah, just make a pretty simple wooden box with holes in the right places.

Re: Wooden GameCube

It's been a while since I've taken apart a GameCube, but if I recall correctly the electronics basically come out as one big piece, which makes it much easier to build a new case around it. Melting the end of a cheap BIC pen and jamming it into the holes on the bottom of the console is a good way to...
