This leverages a Ruida 644X controller (and others) harnessing the U axis and one of the laser outputs to drive a fiber laser.
It looks like it’s just using the 5v output from the U plug, not the actual U axis.
I was so distracted by my excitement and reading of the details in the manual that I scanned right over that glaring detail.
Now I am even more curious about the motion control aspect of this.
It looks like it’s just meant to control a fiber laser power supply, but still use a gantry mounted X/Y stage, not galvo mirrors.
