So as I have been using my X-Carve a lot recently, I had purchased a monitor arm with a keyboard tray and a 24" VESA mount monitor (Asus) and had a Raspberry Pi 4 (the 8gb model) to control the X-Controller with Easel (the X-Carve’s equivalent to the GFUI). Since the X-Carve is Arduino powered (the X-Controller is basically a fancy Arduino with the GrblShield on top to interpret the GCode.
This requires a serial connection (via USB FTDI). So somehow they have magical drivers that allow the web-based Easel to run a serial connection from your computer. Well I had been using my MacBook Pro next to the X-Carve which I REALLY didn’t want to keep doing, A) because then my laptop is in my basement for hours and B) I don’t want my fancy laptop next to the X-Carve. I noted that Easel has a linux driver so I went to install it and discovered that the driver only works on x86 computers running Ubuntu (grrr). On the forum someone has made an open source ARM driver for the RPi. But it wouldn’t work (maybe before the Pi 4?) Anyway after wasting an afternoon fighting with the Pi, I finally said “fine I will get a cheap mini-PC”. So I purchased a tiny little Gigabyte Brix PC (Celeron based) which is slightly larger than a baseball. I got an open-box one (super cheap) and purchased a SSD to replace the “supposedly included 5400 rpm drive” (which was lucky since it in fact did not include a drive) since in no way am I taking an open-box drive (even planning to format it) and attaching it to my network.
Anyway, the huge advantage of this tiny computer is that it is VESA mountable.
But the design is that the computer would attach to a monitor not already mounted to an arm since the hinge of the plate interferes with anything attaching over it.
So that required a new VESA mount. So first I made a simple 3D printed one that sits on top of the pole that supports the arm, but that was kind of stupid since then the monitor isn’t near the monitor.
So I designed a mount that first attaches to the back of the monitor OVER the existing mount plate (with a slot for the arm’s hinge) and then has a VESA mount plate on top of the arm, so the arm can easily articulate with the computer behind the monitor. So I realized that acrylic plates will A) be 10x faster to make it out of, and B) are thin and strong:
(for those who care the VESA mount uses M4 screws which I have a huge number of sitting around in almost every length. Once I get the computer up and running I will mount it and add on an action pic of it in use.
