OpenGalvo OPAL Firmware is now in the open and making progress!
Purpose with the project is to build a controller that can control SLS type machines. This is the first step and covers the galvo only.
I use a Teensy 4.0 (4.1 on the way ) to send signals to a Digital galvo which takes XY2-100 protocol.
In my setup a SN75174N (https://www.ti.com/store/ti/en/p/product/?p=SN75174N) is used as a line driver to convert Teensy 3.3v signals to the differential input the galvo needs. The Galvo used is a SG7110.

Two videos are made to demo function and speed.
