The last post explained what the motion controller needs to do. This post will deal with the actual assembly of the electronics. The G251X motor controllers can run up to 50V, and higher voltage makes higher speeds possible (you need the higher voltage to counter the back emf from the motors, which gets higher the …
The last post described the physical setup of the mini mill CNC conversion. Apart from adding motors to the mill, you also need something to control those motors. Most people seem to just get a G540 motor controller from Geckodrive and hook it up to the Mach3 CNC software. This seems to be a nice “turnkey” solution …
As mentioned over the last few posts of the NC30 EFI project, I’m going to need to fabricate various little metal parts. That’s not something that I’ve had the capability of doing here. Back when I got the ShapeOko, I was hoping it was going to be able to do light aluminum work. While I …
Since we moved here, I’ve constantly been annoyed whenever I’ve tried to find tools or other specific things because nothing was organized. Some things were in the basement, some things in the garage, some things in unopened moving boxes, and it was impossible to find anything. I’ve probably spent more time looking for tools than …
I’ve been thinking of getting a welder for a while now, it seems like one of these “generally useful” things. Finally, I bit the bullet, read a bunch of online reviews, and ordered an AlphaTig 200X TIG welder. This is pretty much the cheapest TIG welder you can get that can weld Aluminum, and while …
I don’t think anyone’s noticed, but I figured I should mention something for posterity: Plane work has come to a temporary stop. Early this summer we found out that we will be moving from LA to Hawaii this fall so Kathy can start her new job as Professor of Astronomy at University of Hawaii, Hilo! …
I got a big chunk of 1/4″ 6061 aluminum plate and tried to mill it, with pretty depressing results. The setup just was nowhere near rigid enough to handle it. The force on the bit would cause enough flexure to pull the bit to the side or cause it to jam into the material. A …
While the ShapeOko worked much better with the Ridgid trim router than with the Dremel, the default spindle mounting brackets for the ShapeOko didn’t fit well because it’s so much wider than the Dremel. To even get it in there, I had to take it apart and remove the height adjustment mechanism. First order of …
As I’m now about to start fabricating actual parts for the Long-EZ, I was contemplating the easiest way to shape the foam pieces. This Long-EZ builder used a router to cut the depressions, but was left to do the tapered parts by hand. Wouldn’t it be nice if there was some way to do this …
In the first part of the “gasoline experiment”, I had just sealed up the cube and was waiting for it to cure and see if it leaked. I realized that it was pretty important to keep the cure temperature as even as possible so as to not produce any pressure change inside before the flox …
