Im upgrading my K40 clone to a 60 watt tube and power supply. I also have a Meanwell supply from an old Ender 3 pro I want to use , keeping the main PSU strictly for the tube driver. However, the wiring is proving to br problematic for me. I wish we could post photos here, too for a better example of what Im about. The stock 40 watt supply is radically different from the Cloudray M60 as far as connections go. I searched the internet for wiring diagrams but no luck for my specific power supplys. your video is excellent in as much as it addresses other issues I will face in modding. Thank you!

For the front vents, you can increase the air flow through them simply by twisting all of the metal strips running up and down. About 15-20 degrees each should do it

Loads of interesting content fella, you missed one crucial thing though. When you took the bed out and messed up the laser mirrors. How did you realign the laser once you put the bed back in?? That was a very important step to miss out. I'd love to extend my printing footprint but I'm not confident in the realignment of the laser. Please help Many thanks in advance sir. Keep up the cool content 👊

Great video Eric! Just wondering how after a year how it's all working for you with the K40? Any other modifications or changes? Did you figure out that taped thing on the waterline by the laser?? 🤣😂😅 I bought the exact same one and have done quite a few mods to mine as well 😊. I think I seen somewhere on one of your other videos that you're from Goderich ON, I'm not too far from you, Windsor ON lol. Good to see a fellow Ontarian on KZfaq!

I would appreciate if you could. Thank you.

Got a K40 about a week ago, really happy with it. The optics seem to be in good alignment out of the box, the bed has a removable flush plate covering the clamp in those things, and the top of the bed seems to be about 1.5-2mm below the focal point of the lens. The extractor fan seems to be a decent equipment fan with a good flow, not one of those junky plastic boxes most of them apparently come with, and the extraction nozzle inside is the full width of the working area and seems quite effective, and it came with one of those spiral foil type hoses, which seems a bit more substantial than the blue plastic ones I've seen with other people's. All in all, I'm very happy with it, as most of the things which everyone says you absolutely must modify seem to have been done for me. All I've had to do myself is properly to earth the case, and to install an ammeter in series with the tube, since I got one of the ones with a digital display. All in all, having looked into these machines a couple of times over the years, I'm only sorry I didn't take the plunge much sooner.
