Hello all. I recently received our new machine from China, which is this one:
ITJ1390 co2 laser engravers - CNC laser video-laser cutting video -laser engraving video - Jinan Itech Machinery Co,.Ltd

Id like to start planning to upgrade this machine, if anyone can recommend what I should start with and what would need to be changed to improve the machine.
The first thing I do know is I hate the software it comes with.. LaserSoft..which I cant even find anyone who uses it,or has heard of it. It doesnt seem to have very much control options when engraving.
I think I could start with the lenses ,and perhaps mirrors?
One thing to note, they sent me everything rigged for European use, even though I requested US. So its rigged at 220V (which is fine) but its 50hz instead of 60hz.
(Itech has repeatedly ignored me about that by the way,and I know theyve received my emails about it,answering questions I made along with the complaint,yet still wont respond about the power specs)

any advice would be appreciated.
