Your eyes are better than mine, it looked connected to me.
lol no sir. I took a screen shot and zoomed in when I saw the video. I was wondering the same thing and had to take a look.

When you need more workbench space!
I may need to find the plans for this.

Amazing motion topography (like the opening credits of Game of Thrones)
Watch it work
Watch it being made

That project looks interesting.

Sisyphus – The Kinetic Art Table, basically a round table covered in sand with a CNC control system underneath that can cause a heavy ball to move through the sand via magnets.
The results are amazing.

How it works (Technical Details)
Hardware overview - All Sisbots are two axis, polar plotters. The smaller versions (for sand fields < 40" diameter) are stepper-actuated, using Trinamic drivers. Brushless servomotors / drives are used for larger versions. High-level control is done by using code written in NodeJS, running on a Raspberry Pi 3. This includes both high-level motion control routines, file handling, and serving a two-way WiFi interface. Low-level motion control is handled by the SisBotBoard (SBB), designed by embedded systems engineer Brian Schmalz (designer of the EiBotBoard (EBB) for Eggbot). Point-to-point commands are streamed from the Pi to the SBB over serial USB, and the SBB does the low-level timed generation of step / direction signals that govern the motors. Software dimmable white LED lighting surrounds the sandfield. Power is provided by a 12VDC universal switching supply for both the LED’s and Sisbot. A single AC power cord plugs into a standard outlet (total power consumption <100W for smaller tables, <200W for 4-foot table).
Software overview - At the lowest level, the SBB runs a custom version of the EBB firmware, and conforms to the EBB command syntax. NodeJS code on the RPi will be freely upgradable as it evolves. Routines for converting standard vector file formats (AI and DXF) will be freely downloadable. Algorithmic tools for composing paths are under development.
The Sisyphus path-file format consists of a text file containing an ordered list of 2-axis vertices, with each line containing the polar coordinates of a point on the unit circle. Paths saved in this format will play on any size Sisyphus (they are scaled appropriately by the software). Designs can be easily translated from traditional Cartesian x-y coordinates.

Cheap! Digital measurement readout.

Yep, that is very cool.
I just backed this Kickstarter for a $99 3D printer, for $100 you can add a laser.
It has a small print area of 5"x5’x5 but it looks well built and it has an auto leveling base. Plus the company has a very good track record of delivering what they have promised.

I almost pulled the trigger and bought one myself but the build area is not that great when you consider you can buy one with twice the build area for another $100.00.
It is also linear screw so the speed is not that great.
This is a great collection of simple fixes and quick made tools. I actually learned a thing or two!

The Z axis is selling on eBay for $137
XCARVE users! This z axis bolted right up. Perfect fit. Works like a champ. Only thing needed is a spacer if you are using the dewalt 611. Cant beat it for the price!

For anyone that is bored with just having three axis to deal with. Crank up Fusion 360 and try your hand at 5 axis control, just $351 (plus you will need a new controller)
Interesting concept but a little pricey and not sure how long it would hold up to constant reassembly.
