The GI4 is an ideal device for machine builders. Not only does it

include multiple I/O points, it also connects to the Automation1-iSMC

motion control via the HyperWire motion bus side-by-side with other

Automation1 drive electronics. The iSMC’s default G-code support 

couples nicely with the GI4’s standard 3-axis XY2-100 or new higher

-resolution XY3-100 support to make all types of laser systems easy

to deploy. Even high-end 3D printing processes are implemented as

simply as traditional 2D processes such as laser etching, laser

engraving, laser cutting, laser welding and laser ablation.

The GI4 includes a data array with more than 67 MB of memory, which

enables bitmap and grayscale processes. Simply download laser on/off

control arrays or high-resolution grayscale values to the drive array, then

call upon these values, synchronized with motion, to control laser firing

and power. Use Part-Speed PSO to ensure accurate and consistent pulse

-to-pulse spacing while calling on the drive array’s memory to control

each laser firing event.

Do all of this while tracking the positions of your servo axes in combination

with your galvo scan head axes using IFOV. Simply route your servo axes

position feedback from the Automation1 servo drives to the GI4 and the

GI4 will combine the galvo and servo positions to accurately control your

process. Even if not a hard requirement, using IFOV can help improve

throughput and quality by optimizing laser on time and limiting the scan

head motion to the central region of the focusing objective.
