I have a K40 that is in need of repair. It needs a new tube, possibly a power supply, and while I’m at it I need a new driver board as the previous owner lost the USB key.
Does anyone have experience shipping replacement tubes into Australia?
Should I fix this one, or look at purchasing a new laser cutter in the next tier up?

How do you know it is needing new tube

I have not powered on my original k40 yet, but I read a lot. If I want to replace anything in my one, I would take a look to Laserweb and the supported hardware. There are two or three boards that are supported. The dongle is just for the original software. If you have the m2nano board inside, take a look to my collection, you could also use a open source software called… k40 Whisperer https://plus.google.com/109140210290730241785/posts/3XWXziTzu8E

Take also a look here for a upgrade projekt

@Phillip_Conroy , about a year ago I was using it and the output power of the laser was dropping. I turned it off for a while, then tried again and had the same issue. It turns out that it was overheating due to a short in the pump turning it into a heater. I found this out by testing the temperature of the water, but zapped myself in the process as I was touching the chassis of the K40.
In the mean time I’ve been using the laser cutter at uni so haven’t needed mine at home to be operational, but have come into some paid laser cutting work, so I can’t really use the uni one anymore.
Currently I get loud clicking noises, similar to shorts, when I try to run the laser.
@BEN_3D yeah I’ve taken a look previously. From memory though my K40 isn’t running the m2nano board unfortunately. I’ll take another look once I get home today. I’m contemplating getting a smoothieboard.
EDIT: The control board in the K40 requires that I use Moshidraw 2012 so that it doesn’t brick itself. Had to fix that once already.

Paul who did you buy your new tube from

@Phillip_Conroy i bought the tube from reci. Search online in ebay for that seller. Alternative is aliexpress seller cloudray but i have not brought a tube from them but bought other great laser things of good quality from them. Also they seem to communicate better than the average chinese seller.

I had a look on ebay and that seller looked doggy, read negative feedback, their are a lot of fake reci tubes,hope I am wrong ,that is why I brought my spt tube directly from spt website
