The tabletop gantry system
marc0 Gantry System
marc0 Gantry System is a high-precision table top gantry system from marco. The machine can 
be used in a benchtop, stand-alone or conveyor configuration for in-line or batch processing. The system uses linear encoders for closed loop position control and the dispensing tool position is monitored at all times. 

The Dispensing Control Unit (DCU) controls both motion control of the robot and the dispensing process simultaneously. This synchronization is unique in the dispensing industry.

The base is a box construction, made of welded steel, stress-free annealed then precision assembled. The surface is nickel plated. For low thermal distortion, all materials in the machine have the same thermal expansion coefficient and positioning is kept consistent even at different temperatures.

All drives use servo motors. The weight of the tool is pneumatically balanced in Z for greater precision and payload capacity. Four high precision encoder measuring systems are integrated 
into the system for precise positioning and closed loop position control. In the Y axis, there are two encoders, so that the position of the tool is read without rotational distortion or skew.
The marc0 Gantry System is suited for integration into an in-line assembly line. The work surface contains mounting points for a conveyor or tooling to accommodate automated loading and unloading designs.
In front of the work area, there is an integrated calibration and maintenance station for establishing machine tool offsets and maintenance of the nozzle. These tools include vacuum suction station for purging, nozzle wiping for cleaning, touch sensor for nozzle position detection and LookUpCamera for nozzle condition inspection. 

Predecessors of this robot have been working inhouse 
marco since 2016 in production for an automotive sensor.
