I think I have some industrial accounts lined up for metal laser work. I think the 20 watt portable one will work for a starter machine. I am assuming if the mark is not deep enough for a customer you can just make two passes.
I have two decent quotes from well known Chinese manufacturers and with direct import I will need to factor in brokerage fees and shipping from West coast port. The Bodor was a lot more money but I kind of suspect most of these are made about the same.
The Bodor uses a Maxphotonics and the Ray Fine uses Raycus source and I am not sure which is better. Both software is EZCAD. Advice, yes I know I should purchase from a USA vender and pay 3x as much for the same Made in China machine, but I am experienced enough to fix just about any properly designed CNC.
