I've got a cheapo Chinese laser that I picked up very cheaply, I've identified the galvos as LP12's, which are a little on the slow side. Would I see a big difference upgrading to 20k galvos? like this set- AMAZON Money is tight so I can't afford a nice set of 30k galvos.
The other issue is the red laser (650nm) is pretty rubbish, it claims to be 400mw but I don't think it is anywhere near, it also looks out of focus for graphics and is not a round dot. Maybe I'm too used to my Argon-Ion laser and He-Ne which have beautiful tight beams. I've looked and there appears to be a lens glued into place for it, I'm not sure if these can normally be focused?
