Check out the DPSS Quick Start Guide on the internal lab wiki for details.

Flash the program to the motion controller

Download the ".dmc" file.
Open the program in GalilTools
"Download" the program to the controller
Execute the program

Set the program to run on startup

Open the Terminal ("Tools" >> "Terminal")

dpss's Issues

Limit switch causes stage to freeze in place

Limit switch routine freezes the program rather than bumping the stage back out of harm's way. This leads to an unrecoverable state where the stage is stuck at it's limit with no way to move away.

Add a homing feature that drives the stage all the way to the right on startup to ensure it's in camera view

Enable jogging a specific amount (similar to GCODE command G0)

In order to enable cuts of parts larger than the galvo's field of view, we can cut in quadrants. this requires precise motions in x and y.

Options:

Enable a GCODE-style interface where you can send commands via serial to move specific distances in X and Y.
Add a "Jog distance" mode where user sets the jog distance and jog buttons are used to move there.
