CNC-2116 - Up and running, sort of (2015-03-21)

Here's the test for the bolt+washer+nut assembly method. The hole for the bolt was just a bit too small and the rectangular hole for the nut and washer just a bit too wide and tall. Still works fine but I'll fine-tune the measurements when cutting these holes on actual parts.
The MDX-3 is currently busy cutting the upper panel for the Dremel 395 mount, I'll post an update in the next few hours.

Here is more pictures of the Dremel 395 mount.
The first image is my web-based "design" software, currently written in PHP and HTML5 (using Canvas), showing the part to be cut. The lines are extra-wide because they represent the cutting diameter of the end mill (1/8 inch or 3.175mm). The light grey line represents the cutting area of the machine.
The other photos are the MDX-3 about one minute before it finished cutting the plate. I still need to get a proper cutting plate with rails and clamps.
The last three photos show the Dremel inside the plate and a small cut I had to do because I incorrectly measured the diameter of the body. Still some mistakes to correct so I'll be re-cutting these two plates tomorrow with the required corrections as well as the back plate for them. In 24 hours I should have a proper Dremel 395 mount with mounting holes, ready to be attached to my yet-to-be-designed machine.
I don't mind re-cutting all the plates again because the CNC does all the work. ;)
It's really amazing to design something on the computer and holding the part in your hands a few minutes/hours later. It's kind of the reverse of "Tron", taking something from the digital world and bringing it to the real world.

Good thing I was still making new joints tests and the Dremel 395 mount was on hold, because yesterday my brother gave me this as a Christmas gift! :woot
The RTX is rated at 2 amps compared to the 1.15 amps of the Dremel 395. If you judge by the numbers it means it should be almost twice as powerful but from the torque alone you would think the RTX is almost three to four times better. It's also a lot quieter at the slower speeds, which is extremely good. And it's more or less the same weight so I won't need an over-engineered gantry to support it.
Step motors: check
Electronics to drive the step motors: check
Linear slides: check
End mill bits: check
Powerful and lightweight spindle: check!

After looking at a few dozen types of CNC joints, I choose the type with tabs because it allows the parts to align themselves in all three axes. A simple manual drilling in one part is required but centering is done by a CNC'ed hole in the other part in front. Kind of hard to mess it up. ;)
Can't wait to finish my CNC machine and start making actual arcade projects, I know it must be boring reading about all these changes after over a year since I started this thread.
Well, here's a few photos, feel free to leave replies, suggestions and ideas!

That's pretty neat. I'll have to remember that method for machine #2.
