Hello,
my first question is: are there some minimum requirements for the computer (Windows 10) to run the Makelangelo software?
I built a polargraph with Arduino Mega, Ramps 1.4 Board and Drv8825 drivers. It runs with 7.24.5 as Makelangelo 3.0-3.2 and firmware 9.1.0 (oddly 9.2.0 is not working with my machine).
Sometimes after a few hours of drawing the machine stops (the intervals are irregular), then I have to restart the computer and software, have to recalibrate the home position, and then I can continue the drawing from last #line. The drivers do not seem to overheat, even after hours I can touch them and they are just warm, but not really hot.
Thank you
Thomas

2021-09-08 at 09:00 #29664art-and-pianoParticipantBecause 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.

The machine was running now for 4 hours and 20 minutes without interruption to the completion of the drawing 🙂
2021-09-20 at 23:43 #29722art-and-pianoParticipantUnfortunately 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.2021-09-21 at 00:19 #29723art-and-pianoParticipantI 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
