Franken-40 - Highly Modified K-40 Laser Build - Part #1

Part #1 of building the Franken-40, a highly modified Chinese K-40 laser cutter/engraver. I will document the build and BOM during the video. The .STL files will be available at the end of the build to ensure all the prints are correct.

Awesome video Bill! Thank you so much for sharing.

damn, man, just what I needed. got a new subscriber! :-)

Looks really good, it would be good to be able to start printing some of the non changing items like covers and feet because I’m guessing it will take a while to get it all printed, thanks for all of your hard work and time making this design.

I started with the housing so those that want to do the conversion could get that out of the way. Have you already printed the laser gantry parts?

[@waynesexton9234]

Hi Bill, no not yet, where would I find the laser gantry stl’s? I really like what you have done, I saw a video of cohesion running with the camera and wow that will be next but one step at a time, first I just need to increase the cutting area and then make the saw blade bed (great idea).

Very interesting!
Could you please do a video about the electronics box. How you arranged components, grounding (in particular in respect to high voltage), etc. I would especially interested how you connect the HV lines between the (now external) PSU and the laser tube.

[@MicroRotors]

That will be covered in video #3.

[@ingom8066]

Thank you. I'm looking forward to that.

[@waynesexton9234]

Hi Bill, how are you making the nicely finished square holes?

[@MicroRotors]

I used a 16 gauge Air Nibbler from Harbor Freight. I used double sided tape to hold 1/8" thick pieces of wood to make a ring a little over the size I wanted to cut. Much like a router jig. www.harborfreight.com/16-gauge-air-nibbler-96661.html?_br_psugg_q=nibbler

[@waynesexton9234]

Great way to do it, will invest in a cheap nibbler to make so holes, I was thinking about cutting slots in both ends so longer items could be feed in and with the cohesion and camera it would be possible to laser long lengths of material.
