This doesn’t need to be done terribly often, but since I was starting fresh and wanting to teach students who had never done this before, I thought the practice would be good. To ensure the spoilboard is totally flat relative to the end mill it is smart to use a large end mill to cut a uniform layer off the top. It’s primary purpose is to protect the machine’s bed from damage caused by the end mill going too far while trying to cut out your piece – a common scenario that happens when your material measurements aren’t perfect or you are slightly off when homing the machine. ![]() In CNC-speak, a spoilboard is a piece of material that sits between the machine’s bed and the material you want to actually carve your design into. Id wanted a 3D scanning probe for some time and finally got one off the big auction site. Has been running just fine in modelling mode on an old Windows Vista desktop. I bought an MDX-40 last year & used the free upgrade to essentially turn it into an MDX-40A. ![]() It’s compact size but spacious work area allows it to fit in most any office, lab, or classroom. Hello, Im hoping there are still some people out there familiar with this scanner. I had already done quite a lot of reading and research on CNC in general over the past few years, and with my experience in DIY 3D printing this felt like a pretty natural step. The MDX 40A is an easy to use desktop milling machine. ![]() In preparation for teaching a class called “How to Make Almost Anything” at Omaha’s Metropolitan Community College FabLab I thought it’d be fun, and a good idea, to do some experimenting with their Roland Modela MDX-40A desktop CNC mill.
