I can’t find any topics about this so I thought I should make one. I’m not too active in this community so I don’t know if this is a known and understood issue or not.
Basically I just got my “K40”. It was advertised as a newer, better and narrower(!) 40W laser. Unfortunatelly I didn’t put 2 and 2 together and what I received is a unit that has a 600mm tube installed. From most listings on Amazon, Aliexpress and such this size is indicative of a 30W tube. It does have a port for a longer tube but that’s not what I ordered.
Be careful when buying your unit (before someone says it, yes, I ordered it on eBay, no, I’m not sure it’ll end favourable for me, yes, the tube was in TEM01 when I received it, no, I haven’t got any local sellers to use (the one shop that has K40 has it priced at just over 2000€ (no, I didn’t mistype the price)).
Here’s a few things I did before I remembered to test the output of the tube. It’s heartbreaking to have to wait for a resolution when I had so much fun with it just yesterday.
Have a better day than the one I’m having
