I have 7 macros that do nothing more than set a dimension in the Z axis. Of the 7, 5 work as expected. For two of them, if I run the macro from the macro tab, they run fine. If I use the keyboard shortcut, I get a message saying the shortcut is reserved for grblHAL.
However, when open the shortcut menu, my two shortcuts are not asterisked. According to the shortcut list, HAL exclusive shortcuts are asterisked.
The two shortcuts are ctrl + 1 and ctrl + 3. The macros that they should run set Z to 3.175mm (1/8") and 9.525mm (3/8").
