There is a tool icon on the right of the screen (the gear) that will open up a control interface. It will show the connection status, and monitors all communications with the printer. You can also manually set the temperature, and use the "jog" option to move the bed around and extrude filament for loading & unloading.
I'd start there & make sure the software & printer are actually talking.
You may also want to ask in the MakerGear forum if you suspect it's a printer quirk rather than the slicer.
