I bought a 40W CO² laser from ebay but wasn’t satisfied with for many reason, one of them was the bed, stock bed cannot be lowered even manually. I was also looking for a new laser head with air-assist when I found this power table/bed.
LightObject.com sell a lot of parts for laser and CNC and today I will talk about this nice product through a step-by-step assembly, here is all delivered parts:
Let’s start the assembly with the lower frame and the four threaded-rod, simply insert the bearing in the frame:
Insert the four axis:
Remove the bearing and the upper lock nut:
Turn all the four nut:
Pre-install the belt and the stepper:
Fasten the stepper with the two screw:
Install the belt-tensioner, with light tension as long as the assembly isn’t done:
Install the bed (and the lock nut):
We removed the bearing from threaded rod, now it’s time to install them in the upper frame by gently pushing them in the blind hole, if it’s hard to insert try another bearing/blind-hole combinaison, never use a hammer !
The upper frame can now take place, don’t forget the previously removed lock nut. Simply insert the threaded rod in the bearing:
Fasten the upper frame with screw:
Almost done, you can now adjust the belt tensioner:
Flip the power-table upside down:
The lock nut is in contact with the upper frame and the bed lay on the four lock nut, it’s now time to lock them all:
And it’s done !
A pleasant hour long is required for the assembly but if you don’t take photography it’s done in less a half-hour !
Here is my power-table in place in my K40 CO² laser (I painted it white because the stock blue color give me cancer !)
