Frozen Window- Jog Motors + Invert

[EdmondsLibrarian]

I made up a dedicated work station for the “Drawbot” / Makelangelo and am excited about the new school year.
Loaded up the latest software. VERY excited about the image resolution preference tab, and improved limits interface. Nicely done. Sure to be kid friendly. (Pictures when it’s working!)

My first challenge was in using the new “drive manually” interface. When I would press any of the direction buttons, the pen would immediately drop up or down without stopping. I would invariably have to turn off the power and reboot.
(Limits of 1100, 500, 1100, 700 which is to say my drawing area is portrait.)

Now my challenge is that when I open the Jog Motors menu, it freezes the program and becomes unresponsive. I’m not sure how the “invert” boxes might have become checked as well. It isn’t possible to jog the motor in or out. The invert buttons are also not responsive. Any ideas? Maybe the log will help? Or is there something else I need to reinstall?

This problem went away after 3 restarts. Thanks for reading.

According to the error log Java is getting really mad that I made it play a sound. I wanted a way to let people know when processing was finished or when a drawing was done. You know… in case they weren’t paying attention.

Thanks for the good bug report. If you have any suggestions to improve things, please let me know.

I’m wondering if I”m having unusual problems because I have as many files as possible on the “D” drive (not C). I’m doing this to try to avoid the permissions problems that come for users at my school. I can customize the generic student log on, but if a student logs on as themselves, I’m going to need a fast way to get the right files into the My Document folder (like for Arduino).
I’m hopeful that a version like for “Portable Apps” could work, so that I could walk up to any computer with the USB pen and make great art! Keep up the awesome improvements.
