Hi, if you see the message "Grbl Ready" after it connects to the port then you should be able to hold down the Ctrl key and left mouse click the house icon (home). The status box will then show you all the Grbl parameters. This is the same as using UGS (universal g-code sender or any terminal program) and typing in $$ [enter].
In the T2Laser trial you can only view the settings, you can't get to debug/advanced mode which enables manual G-Code commands so using UGS or another program to communicate with Grbl will be necessary.
I'm not sure what you mean when you say "I am not able to see the G-code to tell if it is a compiling issue", do you not see any G-Code in the window? The view button should also show you the result.
Using the attached Goofy image, I set resolution at 0.1 and size to 50 x 58 and generated the G-Code (using the trial) and this is the result, horizontal and diagonal scanning. You can see the X/Y steps are correct and the result is also, obviously incomplete due to the G-Code line limit in the trial.
