Hi!

We are thinking about purchasing a chinese MOPA laser.

I've seen a few people on here who own these machines, so if anyone could give us some input that would be greatly appreciated.

We would like to get the 300x300mm model, with 30w. We engrave many small parts, so a large area that we could fit a large jig into would be great.

Is there any great disadvantages to getting the 300x300 lens, as opposed to the smaller 150x150? Is there a visible loss in quality?

Is it worth springing for the JPT M6+ source over the M1+?

Is the lens a consumable, will it wear over time?
