Motorized Stage quits during time course

Hardware
1

We have acquired a used Olympus IX81 with a Sigma Koki XY motorized stage. We are doing time courses with multi ROI, and after ~4 time points the stage becomes unresponsive. We are running with micro-manager 2.0. Has anyone encountered a stage suddenly becoming unresponsive to a computer but still ok with the joystick?

Here is the config file if it is of any use–

Welcome here @Heather_BrownHarding!

FWIW, we have a Sigma Koki controller as well, that has been working for a long time without problems, but I have vague memories of initial trouble (and of course forgot how we worked around that). Maybe it was something along the lines of never send another command to move if the previous move did not complete yet. It may be helpful to generate a Trouble Report (Help > Report a Problem). That allows me to look at a lot of debug output that maybe explains what is going on.
