This is my first post but I've lurked off and on for awhile. Thank you everyone for the valuable information that you share.
A bit of background. I'm shopping for a laser machine to mark anodized aluminum. I own a machine shop and we machine a lot of parts that get anodized and our customers would like us to mark them as well.
I have pricing from Trotec, ULS and I'm still waiting for Epilog. I really like the Trotec machines but the ROI on the big three just isn't there for my needs at this point. If I get enough work on the Chinese machine I'll probably buy a Trotec for marking and use the Chinese machine for cutting but that would be down the road.
Thus my endeavor into the Chinese machines. I've been talking with Weike and Shenhui. Weike has been a bit more responsive but Shenhui has a bit better pricing. Presently I'm leaning towards the Weike LG1200. I've asked Weike about upgrading to servos on the x and y axis. The cost to upgrade to belt drive servos is $2650 extra which includes the Leetro 6575 controller. They said it would be faster and I assume a bit more accurate.
So what do those here think. Is it worth upgrading to servo motors and drives? Pros and Cons?
