Default Hobby CNC mill

Anyone here get involved in any of the small hobby sized CNC mini milling machines?
I got one of the 2418 models that is a DIY set. Kinda like a big boy's erector set. It tried my patience but I got it together. Only has a 7" x 4" working area and the depth is about 1.5". I have wanted for years to better understand the CNC control of machines and I figured this would be a less expensive way to learn. Later I can move to a bigger machine that can do more serious stuff.

Dale; I have a mini-mill Grizzly G8689. I have since added DROs to it. I use it for drilling parts to precise depth. It isn't CNC as most of my parts are one-off.

Taig, Sherline and Grizzly all have cnc table top machines. If you can build your own controller as well it will save a lot of money. I used my Taig to build a larger bench top machine that has an 8 x 18 x 6 high work area.

I started with a 4” x4” working area but also had rotary. Had fun for years before I upgraded to 6” x 16”. Many things can be done in a small area and a great way to figure out how big you may wish to go later.

Well, this isn't a 'typical' milling machine.
It is about 12" square and 10" tall.
This weekend will be the test to see if I wasted my money!
The X/Y travel is just like the cheap laser I have so I'm thinking maybe eventually a system for pen blanks or other cylinders is possible.

Starting to get this thing figured out. A lot more to learn.
I'll need some different cutting bits for sure.
The top cut was done in 2 passes to see how well it repeated the path and to cut just a little deeper. Too deep though as it was chipping out some of the wood in between the channels.
