For those of you asking the question is a Masso controller worth the cost the answer is he'll yes!!! I gutted my laguna M2 4x8 and installed new servos and drivers, a Masso G3 touch and all of the sensors. My total cost was 3500 and it changed the game with my laguna. It took it from a frustrating, problematic large hobby level machine to a easy to operate industrial machine. I was disappointed to find my 50k new machine was powered by open loop stepper motors and a hobby level controller. I had so many problems with it, 4 burnt spindles (18K), program glitches, etc. I had it up for sale and was going to buy another Bcam. 6 months now after rebuild and we use the machine for everything from inlay to full production with no problems.
