Challenges
I couldn't find any pipes that were exactly 1" OD. I had to get some pipes that had 1.06" OD. Even that was enough to make it so I had to modify some of the parts.
I modified Estlcam to always add “G92 X0 Y0 Z0” to the top of the gcode files to set the current position as the home. I found that if I didn’t do this I it wouldn’t cut in the spot I wanted it to.
If I increase the Z and then just leave the machine idle for a while (about 15 minutes) it seems that the Z axis motors just turn off, which causes the CNC to drop.
When I cut the power to the CNC, the CNC lowers unevenly and could possibly cause the bit to smash into the table. To make sure the bit doesn’t smash into the table I 3D printed some spacers (the red thing in the image below). Additionally the spacers are at the exact height I want so that I don’t have to raise or lower the Z when starting a new cut.

USPS Nightmare
So when I got the notification from USPS that the bundle had been delivered I went out to my mailbox a few hours later to get it. It wasn't there. I was very, very mad because it's such an expensive package. I immediately drove to the post office and asked them about it. The manager said that he'd ask the mail person the next day about it.
On my way back home, I stopped at the mailbox again. I thought that maybe she put it in one of the package lockers and forgot to put the key in my mailbox, or maybe she put the key in someone else’s mailbox and maybe that person opened the package locker already and just left the package. I checked all the package box and sure enough, it was in one of them.
I never received one other package last year, and almost lost this one. I think from now on if I order anything expensive I’m going to just have them hold it at the post office.
Next Steps
So far I've had to turn the router and vacuum on with the enclosure door open, then quickly shut the door. So there is a lot of noise for about 5 seconds. So what I'm going to do is reprint the gaskets so that I can fit 2 cords (plus the webcam wire). One cord will power the router and vacuum, the other everything else. I modified Estlcam to add "G4 P60000" at the top of my gcode files, which delays the cut for a minute. Having that minute will give me plenty of time to start the cut via the LCD screen, close the door, then plug in the router and vacuum. Then there won't be any brief loud noises.
I don’t really like the LCD attachment (the part that is zip tied to the Z axis motor). I might redesign the Rambo case so that the LCD can be put on the top or the side. I also might try this Rambo box instead.
I’m going to set up the webcam in the enclosure to stream using my wifi. I have an USB to micro-USB adapter for my phone, so I connected my phone to the webcam. I downloaded an app called IP Webcam which immediately recognized the webcam and started streaming it. Then using VLC I was able to watch the stream on my computer from anywhere in the apartment. I have a Kindle Fire tablet that I downloaded the Google Play store onto, so I’ll probably use that to stream instead of my phone.
Thank you Ryan for making the design available to everyone. And thanks for the shop and making it so easy to order all the parts.
