What I like:
- It comes well-equipped with what others would call "upgrades", with limit switches and a z-probe
- It comes with an offline controller (although it took a bit of figuring out)
- It was shipped almost fully assembled
- 300W motor makes this a mid-grade hobby machine, although the motor is DC (upgradeable to a better brushless motor)
- The drag chains and cabling are well-thought out and nice, although I needed to add a couple of zip ties to hold the motor cable, to keep it from entering and getting pinched in the z-axis carriage.
- It has an external box with a large stop button.
- For machines in its class, it was a bargain.
What I don't like so much:
- The instruction manual was minimal. There was no documentation for the operation of the offline controller. Experienced users will be fine, new users will have to come up to speed.
- The X and the Y axes are belted rather than screwed. That's probably okay at reasonable feed rates.
- The X and the Y axes use the rubberized guide wheels common on 3D printers. I'm expecting to have to change these periodically. With the rubber belts and wheels, and a heavy motor carriage to move (compared to a 3D printer nozzle), I'm concerned about accuracy.
It's going to need a dust collection system for serious work. I'll build an enclosure for mine with a 6-inch fan to a filter (I've previously used a pillowcase) to capture dust.
It's a great value. I can make things in minutes that would take me hours without the CNC. I'm changing professions from being a mechanic to woodworker.
