As far as accuracy, we are still working on that in the software. It is very precise (repeatable) but accuracy is going to depend on many things, including how rigid your frame is (anchors in concrete work very well here) and so most people are getting around 0.5-1mm of accuracy (so +- 0.02-0.04")
This is not a very rigid setup, so your cuts are not aggressive. If you have the space and budget for a big machine, It will be more accurate and FAR simpler software, but the maslow can be packed in a 16" cube, and setup anywhere you can glue down 4 anchors.
A good lowrider setup is a good option. If you can set it up so that you can use the table for other things when you don't need the CNC, it can be especially good.
The key feature you are missing is that it is a sled that rides on the workpiece, so the cables are just moving it in one plane, while the spindle goes up and down relative to the sled.
So it doesn't need the big, rigid gantry of a traditional machine.
but it also is limited in that you can't cut away too much of the surface of your workpiece, you need to leave enough to keep the sled from falling into the cut.
There are also people using the cheap chinese spindles instead of the Dewalt router. any spindle <67mm diameter at least 4" long can be made to work by putting a sleeve on it.

There is also a frame posted a few days ago that sets up with 6x 8' 2x4s https://forums.maslowcnc.com/t/maslow-4-collapsible-frame-fo...
