UGS freezes when opening gcode files

What happened

When trying to open a .tap or .gcode file UGS freezes and becomes unresponsive. Nothing loads and I have to close it.

How to reproduce

I can get UGS to load normally using a right click "Run as a program". Once it has loaded everything appears to work I can load plugins, change settings and I can control the CNC to zero it out and move it. But when I go to open a toolpath UGS freezes and becomes unresponsive. It just locks up. I tried to change the configuration file by adding "-J-Xmx2048m" and that didn't help. Attached is the log from UGS as it comes without the extra memory. When UGS is frozen all other programs seem to work fine.

This is the version of Java I am running

openjdk version "21.0.8" 2025-07-15
OpenJDK Runtime Environment (build 21.0.8+9-Ubuntu-0ubuntu124.04.1)
OpenJDK 64-Bit Server VM (build 21.0.8+9-Ubuntu-0ubuntu124.04.1, mixed mode, sharing)

The terminal window has these messages in it

This happens every time using Ubuntu 24.04 lts, the latest version Ubuntu 25.10 and the latest version of Linux Mint. I tried two different file extensions .tap and .gcode. I tried to use files that I have used in the past on a Windows 10 laptop using UGS as well.

Any help would be appreciated

There should be no need for changing memory settings. The "-J-Xmx2048m" would cause UGS to use less memory than the default which is 85% of the system memory.

The Java comes bundled with UGS, so there is no need to install it separately.

Looking through the logs, it could not finish the preprocessing of the gcode file. I would expect that if there was an error with the gcode it would have been printed.

Can you make sure that there is disk space left on /tmp with df -h. Can you share your file /home/cass/ugsplatform-linux-x64/Toolpaths/ThinkBox.tap

It did not like to upload the .tap file so I zipped it. Hopefully that works for you.

I tried two different versions created by Carveco Maker. I never had this problem with my Windows 10 machine. One of the versions was gcode for UGS in millimeters
