Potentially different sized K40 Build? DSP conversion
Posted: Fri Sep 16, 2016 2:48 am
Hey LightObject,
So i have researched to forum extensively, but have not found solutions to my problems and was hoping you could help
Some of them were mentioned here: viewtopic.php?f=70&t=3159&p=16239&hilit ... psu#p16239
I have found the links to the correct wiring diagrams for the unlabeled PSU that came with my K40:
However I have two problems which no one has posted solutions for (that I could find), one of which dcrump70 mentioned:
When the Y Limit switch is installed on my K40, there is not enough vertical clearance to get the CNC rig back into the machine. The fit is so tight that the switch would almost certainly get crushed if i tried to push it in… Im not sure how to get it back in.

And second, the X axis motor uses a single ribbon Cable, not the 4 wires described in the wiring diagram provided.

I have done some research and found several suggestions on this post (the only thing i could find on the matter)
https://www.reddit.com/r/lasercutting/c ... ions_here/
1: Desolder the ribbon cable connector off of the control board that comes with the laser cutter.. Then solder wires onto the appropriate leads for the x axis motor and limit switches.
2. Buy a breakout board for the ribbon cable. With that, you just plug the ribbon cable into the connector on the board and then solder wires onto the appropriate places on the board.
3. Or to solder wires directly onto the small PCB that is right next to the x axis motor
Any suggestion on which route is best?
If it is 1 or 3, how do i find it which leads are the correct ones for the wiring diagram provided on the forum?
ALSO
The wiring diagram says the digital meter should be connected to the PSU, however I don't see anywhere I could connect it on my PSU

Perhaps this is this mysterious unlabeled PSU... Do i need to connect that wire to one of the ports in the front?
and LAST QUESTION I PROMISE
Are the limit switch connections the only ones that needed to be soldered? Can everything else just be wired and shrink wrapped?
Thanks to anyone and everyone that took the time to read.
Hoping to figure this out and maybe help anyone else whose encountered these problems!
Any info or resources would be so helpful and appreciated,
having fun with the build and hoping to get these riddles solved and start using the machine soon! =]
