I tried also now to run the new software 7.26.0
But when I try to start it with start windows.bat I get this error message:

Error: A JNI error has occurred, please check your installation and try again
Exception in thread “main” java.lang.UnsupportedClassVersionError: com/marginallyclever/makelangelo/Makelangelo has been compiled by a more recent version of the Java Runtime (class file version 59.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Unfortunately all these these efforts had no constant success in the last few days. The machine still stops drawing, sometimes after 15 minutes, sometimes after hours of drawing.
I tried all these things:
– Increase maximum RAM heap size for Java
– Increase swap memory in Windows
– Disconnecting from the Internet and turning-off Windows firewall and turning-off Windows Defender while drawing.
Could you please help me with this problem? I’m really desperate.

I think I found a solution: for Java I increased in the control panel the maximum heap size of memory to the full amount of 4 GB RAM that are installed in my notebook (with “-Xmx4g” in the Java Runtime Parameters). The machine was running now for 4 hours and 20 minutes without interruption to the completion of the drawing 🙂

Because I built the robot by myself with the components I mentioned, I have not the possibility to run from a SD card. So I thought maybe the computer has to have some specific requirements to run the software flawless.

Thank you for that preliminary solution.
