Hello community, thank you for being a resource - any help is greatly appreciated.
My Chinese laser arrived in February and after leaning the machine it was working wonderfully, until the power supply went out. It's still under warranty, so after a lot of hassle, the company I purchased it from sent a replacement power supply. Yesterday, I replaced the power supply and everything seemed to be in order ... at least for cutting.
Engraving is a separate issue. With the original power supply, engraving was clean and crisp but now it is blurry. (See attached photos)
I've checked the alignment, we seem to be good there. I've inspected and cleaned the mirrors and lens - no apparent issue here.
I saw another thread that suggested reloading the design file into the unit - I only noticed a minor improvement deploying this technique.
My theories at this point are as follows:
- The company may have sent me a wrong power supply unit - box is labeled 40w and I have a 50w machine.
- I could be experiencing power loss - have not yet tested since I need to get a proper tester/meter.
- The tube could be bad ... its original with less than 30 hours on it though.
- Or I just have bad luck and this machine was a terrible idea.
Any help and suggestions would be appreciated. Many thanks!
