Finished rebuild of my K40 laser cutter

Postby Winstonc » Sat Mar 18, 2017 1:33 pm

Finished rebuild of my K40 laser cutter using LO 45w tube and case extension, 40-60w LPSU and X7 DSP kit, plus power z-table kit. Very happy with results!

Really nice neat job! Really impressed!! All lined up and ready to go? You changed the laser head out too? That how you got the Z table to fit?

Thanks.

The z-table would fit anyway (I also cut about 1" off the exhaust extractor outlet), but yes I used the LO head with the air assist and changed the mirrors and lens.

How did you go realigning the laser tube given its larger diameter. From my calculations you have to drop the existing clamps down 2.5mm to accomodate the overall 5mm higher diameter. The easiest thing is to shave some of the existing mounts, or raise the xy stage and primary mirror 2.5mm.. I've got the extension and the 45w tube, but haven't tackled it yet due to this issue..

Are you able to send some pics of the laser tube area and more details on how you addressed this ?

They are the same diameter at 50mm so no adjustment was necessary.

I really like how it all came together for you. I'm just getting started. Last night I laid all the parts out and reviewed the wiring diagram only to realize I was missing a few parts (that I failed to buy). So i have to wait on them to come in. Meanwhile I'm just continuing to get ideas of how to put it all together. Thank you for posting.

Did you make the blue plate that the X7, master power switch and ammeter fit into? or did you buy that somewhere? If the latter can you share where?

Also the limit switch on the electronics compartment, is that a small wood box that the switch is in?

Did you have to use any limit switches on the z axis?

The blue plate is acrylic cut on the laser that I knocked up in Fusion 360.

The box that the micro switch is in I drew up in Fusion and 3D printed and yes you need two limit switches for the z axis. Again I just 3D printed the bracket or you can laser cut from the design that is on this site.

Hope that helps

If anyone need the acrylic mounting plate, I can make some in my shop. I can do stainless steel as well 'cause we have laser fiber machine for metal cutting
