Lasersaur ported to Ubuntu 16

Posted by on Dec 3, 2017 in Digifab, lasersaur | No Comments

I’ve been having annoying reboot problems with the stock lasersaur distribution.  It’s probably my own damn fault, I fiddled with a package contents or installed a buggy version of something ~3 years ago. So there are also a number of security patches and software updates I’d like to have on all my digifab hardware.  I […]

I’m making some containers for a client who needs to evaporate water from a solution to get the weight of the solids.  It’s straightforward high school chemistry: weigh container add solution dehydrate water in a special enclosure weigh container + solids now you have the weight of the solids.

Q: Ok, so now you have a 3d printer in your house. What do you print? A: More 3d printers! So we have that joke finally out of the way. How about a tripod mount for the (then) shiny new Kinect?

I built Cupcake #235 and in my first few prints discovered it required maintenance, adjusting, tweaking, etc, to make a good print. I designed and shared some first order tool holders that made my life a bit easier.

A clean Studio is a Happy Studio

Posted by on Aug 1, 2017 in Design | No Comments

Some days when I get frustrated with a project or a client or just plain adulting, I take a mental break by reorganizing my studio. I get way more work done in a clean studio then when it’s a total mess. It’s also a safer studio — tools where they are supposed to be, no […]

locking up the UI for safety

Posted by on Jun 1, 2017 in Digifab, Warifuru | No Comments

My initial plan for warifuru was to lock up the UI during an actual laser cutting operation.  There would be one floating control panel that controls the cut, and after the cut is started the only options for the operator is to stop/pause the cut. Looking at the new lasersaur API and thinking about other […]

I put a lot of effort in to the front end of warifuru looking at use cases, other software, and how people use laser cutters.   Also did some crash-course learning of Qt5 — which I like way more than Cocoa/iOS — and got a sketch together that could parse DXF in to an abstract model […]
