Hi everyone, thanks for tuning into the Hac Chat today. I'm Dan, I'll be modding things today as we welcome Matt Hertel and John Allwine from PocketNC.
Hi Matt and John! Can you start us off with a little about yourselves?
John Allwine12:01 PM
Thanks Dan, sure. My background is in software development, a lot of web development, but I took every 3D graphics course I could in college and spent a few years employed as a visual effects artist. I've since dabbled in mobile development, electronics, 3D printing and CNC in general. I spent a couple years teaching computer graphics at MSU as well as a number of STEAM topics at our local Children's Museum to get their STEAMlab off the ground. I started a blog called Allwine Designs to document my various projects (a couple have been featured on Hackaday). Along the way, I met Matt and Michelle at various startup events here in Bozeman and convinced them that they needed a web interface to the Pocket NC and have been leading software development at Pocket NC for the last 2 and a half years.

I helped start Pocket NC around 10 years ago. I've never been very coordinated so I've always like the idea of CNC. My background is as a machinist. I went to electrical engineering for a couple years but decided to start this instead. These days I get to spend most of my time designing and making new things which is awesome.

Before Pocket NC I was working as a machinist in aerospace in Washington state.
Funny you mention coordination - I don't think people realize how much of a skill manual machining really is. I really respect it, and hope to achieve some semblance of skill someday, but I'm glad CNC is there to back me up.

I had a machining class in university. Teacher tough we were crazy operating the mill in 2 axes at the same time. But I prefer coding my way to a part now.

What was the impetus for launching a 5-axis CNC machine for the desktop? Seems like it would have been easier to do a traditional Cartesian machine.

Futher to Dan's question: I absolutely love that Pocket NC took the concept of 300k machines and brought it to the 6-12k USD price point. I'd liken it to what Makerbot did for 3d printing, or Form Labs for SLA. Now that you have been in the market for a while what has stopped there from being a 3 axis mill that could handle metal. Right now there are < 600 dollar chinese "mills" that can barely do wood or PCBs, and then a gap to 10 - 15k for entry level 3 axis. Is it really a market gap, or is there no market need?
matt12:09 PM
At one point there was a section on MakerBot's website that was called the "MakerBot Mill" and it was blank but just asked if anyone was interested in developing it. We started with a 3 axis machine, but Michelle didn't like the first design and we could see there was already a lot more competition in the 3 axis space so we decided to go 5 axis since the mechanical design is really our strength.

In our opinion, Carbide 3D and Bantam Tools have good machines in the price range you're talking about.
Yeah, I guess the 3-axis market is a bit crowded.

Did desire to machine an impeller play any role in the decision to go 5-axis?

We love to see projects revisited, especially when new materials or methods make it worth giving the first design another go around. This twin-turbine vacuum-powered Dremel tool is a perfect example of what better tools can do for a build. You may recall [JohnnyQ90]'s first attempt at a vacuum powered rotary tool.

Not the impeller specifically - saving setups when machining from multiple angles was probably the bigger factor. But watching...
