I'm trying to use it with GRBL 0.9j, but not having any luck.

Could you also include a short example?

This is the G-code I tried:

$H
[[WaitForDoneMessage]]

----
This is the G-code which I used as a work-around:

$H
[[Delay 7]]

----
Ideally, when working with GRBL, it should emit the "?" command, examine the response, and if it doesn't begin with "<Idle, ", then wait for a short period of time and repeat.

Here is a link to GRBL's current status command's documentation:  https://github.com/grbl/grbl/wiki/Confi … ent-status

If this isn't compatible with the [[WaitForDoneMessage]] command, then perhaps a [[WaitForIdle]] could be added?
