Granite Gantry Positioning System (Large XYZ High Speed Precision Gantry Machine) 

It operates in gantry mode with controller & drivers from ACS Motion Control. And could be integrated with Standa LUMS - Laser Machining Software: Universal Micromachining.

No gears are used. Ironless brushless (direct drive) motors are used only.

It is universal and can be used in both applications. This particular precision gantry system is implemented in semiconductors manufacturing.

@@StandaLTD amazing stuff keep it up!

I've done the same thing before. It's a linear stage. The reason I did it was I wanted the bridge on the bearings for other uses besides supporting the gantry. I would suspect they make the linear stages for independent use and multiple axis usage.

@@chrisf8584 never more than 2 rails per axis. otherwise its overdefined. but who cares. 😂 let it run🤘✌️

@@wildniscamper7276 If I can ask what is the drawback other than added cost of the second rail?

@@chrisf8584 well, in theory you need two fixed linear rails and the gantry should be fixed to only one side and have a sliding connection to the other rail, to allow for expansion. if you double the rails you have more potential tide spots and deformation and no benefit compared to using one bigger rails instead on two small ones.. have a look on big machine manufacturers..the nerver use 4 rails..for a reason.. cost and maintanace not mentioned..

that doesn't apply here@@wildniscamper7276
