Firmware tool has missing GRBL options for machines with more than 3 axes

[zalexzperez]

Hello,

I'm using grbl-mega-5x on my 4-axis machine (cloned X and Y, that is, two motors for X and two motors for Y). The axes are defined as follows: AXIS_1_NAME 'X' AXIS_2_NAME 'Y' AXIS_3_NAME 'X' AXIS_4_NAME 'Y'

In the Firmware tool window, I set the "Generic CNC" profile. However, the firmware tool only shows settings for machines with X,Y and Z axes. I understand the program is only conceived for 3-axis machines at the moment.

What's interesting is that the exported json settings file does save my 4th axis settings, but unfortunately after importing this file and applying the settings, the 4th-axis settings are not applied in the grbl console. I think that's an inconsistency.

Great program, by the way!
