Wow! That's an amazing work of art. I'd bet that it will still be as amazing in 100 years.
What you're seeing is the characters, like Chiloquinruss said, being encoded.

The above explains it.
To be absolutely sure you have the right settings for 360 degrees, rotate the indexer 3600 or some large multiple of 360 and see if it ends in the same spot. This will magnify errors so it will be...
Nice job! +1
>> Does the difference in Amps matter or will either of these be OK?
Both are so close as to make no practical difference. It's the CFM that matters most, and of course the volts. Get the higher...
One way you can refine this number is to turn the indexer 3600 or even 36000 degrees and check the drift.
>> Not sure what you are referring to as home for the cut file.
What do you have set as the start/home position in the material settings? If you're moving off the 0 point for the indexer, then the...
I have a 2013 PRS Alpha with the Shopbot supplied 4hp spindle. The springs hold the weight just fine. Still good after 8 years.
What do you have as the "home" point for the cut file? If the central axis (the one that doesn't move) home coordinate isn't at zero, then weird stuff happens with the rotational axis.
Why are you...
I needed to get the exact geometry off of a rubber part and used polymer clay to do it.
The Sculpey Premo clay I used has the consistency of warm beeswax and is pretty easy to work. Once fitted to...
I suggest removing the debris and kindling from your shop before a fire destroys your building. One oily rag. One spark from a grinder. One overheated cord. Fire safety is not a part time job.

I was beset with making a concrete grave marker for a beloved pet and decided to use machining wax to start the process. I hadn't used it before so didn't know what to expect.
Here's the product:...
Perhaps an irrelevant tip:
An indexer makes for an excellent hold down device for doing multi-sided machining.
I've done it with two, two-sided files.
You might volunteer to replace the pinions as that is the surest, simplest and cheapest way to restore the tolerances to a SB. The pinions probably last no more than two or three hundred hours before...
Ya, good luck on 1/16" with any natural material other than stone.
For wooden electrical plates, I strongly suggest placing a thin layer of steel behind the switch. It might even be code to do so. I've made dozens of switch and outlet covers out of oak. They turned...
Thanks! Yes, 80/20 isn't cheap. I've built a lot of things out of their extrusions. Most of the material I bought from ebay or from recyclers. I find using their materials to be quite satisfying as...
Nice work with the 80/20 extrusions. Can you say what the total cost was for the project in materials?
Thanks.
It's better to use metal ducting than PVC. Some use it, others, like me, think it's a bad idea due to static electricity buildup. If you live in a moist climate, probably not as much a problem. Metal...
Seven years of cutting aluminum and using a cyclone (an Oneida 2hp model) dust collector without any explosions!
Any threat of aluminum being explosive would require it to be ground to the point...
I suggest having on hand several 1/4" two flute upcut end mills to start with. They are the most commonly used and the least expensive. You'll likely break a few of these when you start out so having...
The larger the diameter of the cutter, the more it will magnify any out of plumb condition you have on your machine's Z axis. A 2" flat bottom cutter would be fine. Shopbot has a router bit starter...
I think you'll find the assembly process easy, especially if you have helpers. I assembled my 60x96x12 PRS Alpha by myself with a tiny bit of help from my then 5 year old daughter. That was back in...
