This is a mini-powered bed designed for the "K40" also named "D40K", small desktop CO2 laser machine. With this Power Z Table it turns the K40/D40K easily handles object of different thickness. The traveling distance is 70mm (2.7 inches). By having this power bed, you save a tremendous time of doing height adjustments or focusing point adjustment. Without a good focal point, you won't be able to get detailed engraving. Plus, cutting power drops greatly if out of focus. The power bed is great for other projects as well when lifting feature is needed.

The unit comes as a kit. It should take less than 90 min to set it up. It's fun to build it!

Well Made
Z-table seems very well made. Assembly is pretty straightforward. Getting it wired and working with the C3D board and Lightburn software was quick and easy. Everything seems to work as it should. Great addition for the K40.

Exactly what I needed
I bought this to install in the K40 I’m slowly turning into a capable machine. The package was shipped quickly and arrived when it was supposed to. Packing was very good and it arrived in good shape. Assembly was simple and straightforward, as was installation. Now, I have not actually used it yet. I had to order a stepper driver for my aftermarket control board and it isn’t here yet. I also had to order a probe that fits on the laser head so it will adjust automatically. My one minor complaint is that Lightobject should stock this probe. I had a little difficulty sourcing one from China. I *absolutely* would have ordered one along with the bed, even if it was a few dollars more. I am happy with this transaction and will be ordering more from Lightobject.

Excellent Value & Service By Light Object Team
I had the Z axis table together in 20 minutes. Packaging missing a couple parts, but Light Object was prompt in shipping out replacement parts. Well designed and construction. I also ordered a secondary power supply and a rotary suitable for the K40. Pleased with EVERY purchase I've made from Light Object.

Reasonable price, great addition to a small machine
Really easy to put together. I used a machinist square to get the top and bottom sections aligned. Took 30 minutes or less to assemble. The only issue I have with it is the threaded rods are just a tiny bit shorter than the aluminum frame rods. This causes a little bit of play (few hundredths of an inch) in the table. If you just press it flat before using, I don't see it ever being a problem. I polished the aluminum rods for a smoother appearance. I have it hooked to a Gecko G201X stepper motor driver. I will probably add two limit switches and definitely bond a steel ruler to the top for ease of use. Overall, the price is very reasonable and I really like the table. Before putting the top blue piece on, thread the rods through the brass nuts just a few turns and place a flat bar on top of the nut. Rotate the shaft until it touches the top. Do this for all four. Your table will be perfectly aligned. Don't put to much tension on belt. You'll wear it out or the motor will stall.
