Hello, we have 80W galvo laser using F-theta 210x210mm lens. I am facing problem with details. we were using plotter based engraver (K40) before. they made really good job but its plotter based so speed is limited. as we grown to bigger company we start to find better and faster solution. so we bought galvo head based machine BUT we have problem with engraving (we are engraving to the wood). The engraving is not sharp as the engraving on our previous K40 lasers. You can find the photo of results of both in attachements. The first thing which i was thought is wrong is focal lenght. but we mesuare it and we have right focal point (300mm from lens to surface, but ofc we tried a lot of disctances but never achieve good results)
We are using EZcad software and a tried a lot of HATCH settings sometimes i had better results sometimes it was really horrible. Biggest difference is that we never get sharp edges on galvo like we made on K40 engraver before and also details is big problem.
When i made just simple thin line (i set it to made the thinnest as possible) on both machines, the line made by our new galvo laser made it maybe 2 times thicker than K40 laser.
So i am thinkint if there . can be problem with lens or galvo head or output of beam from tube is too thick ?
Can you anybody help where can be a problem ?
Thank you for any help
