Wanted a new control panel for a long time, now it´s almost done.
This is a prototype of the layout. I have ordered a new button-pad, thats why it looks crazy with the old one still there 
Temps showing PSU temp, water tank temp, and the third is for the 2nd loop outside the window with a radiator.
With theese buttons i can controll red dot, lights, fans, air assist, water pumps, exhausts and autofocus without scattered buttons or glued buttons on the old panel
Very nice did you make an entirely new sheet metal door. This is not a K40 (the depth of the cover)?
It´s a K40.
I cut out a large area and inserted a acrylic panel in the metal lid and wrapped it with vinyl 
Going to wrap rest of the white metal in the same color.
The black piece with buttons is just a thick vinyl sheet too.
The front lip on the doors are much bigger than mine? Did you cut the front of the cabinet?
Nice job on the switch/meter panel.
Same as Don, the front of your doors are also much larger than mine. I think mine is only about an inch high on the front of the doors.
Ah, yeah its the upgraded/newer version of K40, sometimes refered to as K40D. Inside is upgraded aswell.
Wait… autofocus? Im listening…
Arduino controlled stepper motor moving the lens until the sensor touches the surface. The sensor is on a pre-set height and after that it backs off 3 revs so the sensor isnt dragging on the material.
The system knows where the exact height (focus) is to cut or engrave.
It´s not actually checking the optic focus, it just moves the lens to a pre-set distance i measured.
Had it manually earlier, but it was cool building it motorized.
No matter what thickness on the material i use, one button and boom, it´s in focus.
First prototype is working now, i´ll post a video of it tomorrow
@HP_Persson You mention that it doesn’t matter what thickness material you are using, so does that mean you have to reset a “thickness” setting for different thicknesses? Because say 6mm thick compared to 3mm thick is 1.5mm difference in the focus point…
Seems like a great idea though
I´m working on making it to count revs/steps properly away from absolute zero (home) to identify the thickness with 0.1mm resolution, as you mention what i described only works for engraving
System knows were zero is, and when the sensor stop it using the calculated amount of travel done it “knows” what thickness it is and can move the lens to a proper focus.
So far only coded a small piece of this in 0.5mm resolution , but i´m getting there
Not yet found a better solution than counting steps to perform it, if someone has a idea i´m glad to try it out
Quick pic without the lens/sensor/red dot/airassist assembly.
(and no, the final version will not be 3d printed, but aluminium or brass )
