Re: HDPE suitable for ShapeOko structural parts?

The MTM Snap machine (http://mtm.cba.mit.edu/machines/mtm_sna ... index.html) is mostly HDPE, but the construction is pretty different from the Shapeoko, and it looks to have a much smaller envelope. Probably works well for light-duty applications; it looks like it can mill PCBs pretty well.

Re: Adobe Illustrator CS2 - for free from Adobe

Let's try to keep it civil guys. The nice community is one of the biggest advantages of the Shapeoko, and I think we'd all like to keep it that way. Arguing about whether Illustrator is better or not than open source alternatives is deviating from the topic of the thread, and open source vs propriet...

Re: GRBL Freezes while sending a file

I've seen issues with USB/serial communication with arduinos with the Adalight code from Adafruit (for ambient lighting) where communication would shutdown seemingly randomly after a long duration. There is a setting in Windows under "control panel / power options / advanced / USB settings / USB sel...

Re: Success!! PCB with Shapeoko

It increases driver temperature significantly. The driver is sourcing the most current when the motors are in hold. If holding is enabled you'll need to turn down the current pots to keep the temperatures reasonable, or have a pretty good cooling system.

Black Mesa Desk Ornament

I'm finally cutting things! I routed a pocket in my spoil board for PCB milling, but I haven't gotten around to trying that out just yet. I wanted to make something more interesting than a rectangle, so to get more acquainted with 2D toolchain I cut out a Black Mesa logo (from the Half Life games). ...

Re: Easy Hold Down Table

This was one of the ideas I had thought about for hold down when I first was building everything. Those T-nuts are surprisingly hard to find in hardware stores or online from places with a decent shipping price for small items. I have 4 of them sitting around, since it seems to work well I'll have t...

Re: Backlit cedar box, LED help please.

I'd second the MSP430. The launchpad dev board can be had for $5, cap and voltage regulator for running it standalone would only be a few bucks, and it draws next to no power. I think the energia project ( https://github.com/energia/Energia ) supports almost all the arduino library on the msp430, so...
