- This video is my attempt at providing a demonstration of the steps required to assemble the Light Object Power Z-Axis Table for the Small K40-type laser. Below are more detailed written steps for you to follow if you dare!

Author’s Note:
The below assembly instructions are in no way associated with Light Object and represent those steps taken by me during assembly of the power z-axis table I purchased for my own personal use. These instructions were developed to assist a typical Do-It-Yourselfer (DIY-er) who has a general familiarity with common hand tools and their safe usage. I make no guarantees, so you follow these instructions at your own risk.
1. Tools and Materials
13mm Wrench (x2), #2 Phillips Screwdriver (x1), 3mm Allen Wrench (x1), and Thread Locker, Removable (Loctite 242)
2. Assembly Instructions
1. Lower Frame Assembly
a. Apply thread locker to each screw prior to installing. Install four support stanchions onto lower frame assembly by threading one M3-0.35 x 6mm flat head screws through the lower frame assembly into one end of each stanchion.
b. Insert one bearing into each of the recesses in the lower frame assembly.
c. With the pulley downwards, hold the bed nut assembly stationary and turn the lead screw counterclockwise (anti-clockwise for those in Europe) until the bed nut is approximately 2-11/16-inch (68mm) from the pulley. This step pre-positions the bed at each corner to (hopefully) prevent binding during operation later.
d. Insert one lead screw, pulley end downward, into the of the above bearings.
2. Stepper Motor Assembly
a. Loosely install ribbed belt over the four lead screws.
b. Disassemble the stepper motor mounting bracket by removing the three M2-0.35 x 5mm flat head screws retaining both halves. Be carefully of the bearings as they can fall out and get lost!
c. Apply thread locker to each screw prior to installing. Attach the stepper motor to the L-shaped portion of the bracket using the four M2-0.35 x 10mm screws. Attach stepper motor so that the electrical connector will be pointing towards the shorter end of the lower frame assembly when installed.
d. Attach lower bracket half to the lower frame assembly using two M4-0.35 x 6mm flat head screws. Apply thread locker to each screw prior to installing. Screws are threaded through lower frame assembly from underneath.
e. Feed belt between stepper motor bracket pulleys and around the drive pulley.
f. Attach upper stepper motor bracket to lower bracket half by aligning the belt rollers with the lower bearings. Apply thread locker and then reinstall the three M2-0.35 x 5mm flat head screws.
g. Place one washer on each cap head screw and then loosely install belt tensioner by pressing the tensioner pulley against the belt until the tensioner hooks over the lower frame assembly. Loosely install cap head screws. Do NOT use thread locker here as adjustments may be required in the future.
3. Z-Axis Bed Assembly
a. Remove the jam-nut from the four bed nuts and then install bed over the four support stanchions and leads screws. Ensure the bed is seated on the four bed nuts.
b. Adjust the bed nut position as necessary to level the bed.
c. Apply thread locker and then reinstall jam nuts to hold bed firmly in place. Tighten using two 13mm wrenches.
4. Upper Frame Assembly
a. Place a bearing on the top of each lead screw.
b. Carefully lower the upper frame assembly until all four bearings are seated in the frame.
c. Attach the upper frame assembly to the four support stanchions by threading one M3-0.35 x 5mm flat head screws into one end of each stanchion. Apply thread locker to each screw.
d. Adjust belt tension until there is approximately ¼-inch (6mm) deflection in the longest stretch of the belt. This is the initial tension setting. Further adjustment may be required once the table is installed in the laser machine.
Thank you for the video, for the price of this, i cant believe it doesn't arrive assembled, and with a pancake style stepper motor so you have better depth.
It's not bad for a starter setup and the assembly was rather easy. I'm just getting into playing with a CO2 laser and didn't mind putting the bed together.
Dear TopSnipe, I am 74 years old and I have a question:
Bought a Lightobject Z table for my K40, am now looking for the software setup for my Cohesion3D board.
The table is controlled via the Cohesion3D display.
Can you help me with what and how to make these adjustments to the software.
I live on Curacao and no one can help me here.
Love to hear from you, greetings
Marinus Boom
Dear Marinus, Sorry for the delayed reply. I had typed up a reply several weeks ago, but for some reason it never posted.
I use the Lightburn software to manually control the table height. The software can be downloaded and tried before you commit to actually purchasing at lightburnsoftware.com/pages/trial-version-try-before-you-buy.
There are several buttons in the program that allow you to raise or lower the table. The Lightburn website also has a section with a variety of tutorials to aid your understanding.
Hope this help and again, sorry for the delayed response.

Do you have arduino code to drive the table that you could share? Regards mike
mikesfarm, unfortunately I do not. My table plugs into the replacement Cohesion3D controller board and I use the LightBurn software to control Z-Axis adjustments for the table.
Will ot work with omtech board?
Hey, mister! Do you have the rights to that music?? Mozart gonna be pissed when he finds out you're using his tunes without permission! 🤣
