I installed Cura 4.3.0 and Slic3r 2.1.0 on all the laptops, the two machines by the printers and the two machines in the electronics area.   I also figured out how to prevent all the built in filaments from being displayed and only allow the valid filaments and configurations to be displayed based on the machine selected.

I also updated the class slides and copied them onto all the machines.  You will find the PDF file next to the Ultimaker Cura 4.3.0 and PrusaSlicer Icons.  I attached it to this post if you want to look before you come in.
