RRF 3.3.0 - printer does not know he is in pause

[Argo]

Hello dear Duet3d community,

I came across a bug I thought was fully fixed.

How to reproduce:

• printer prints
  -> filament runs out and FW runs pause.g
  -> filament unloads (see conditional gcode in pause.g below)
  -> printer forgets it's state and I can't resume the print afterwards

In an older FW version the printer directly resumed printing when messages were in pause.g.
This time the printer just forgets it's state.

Workaround would be to delete the messages but I don't think it's an intended behaviour?

@argo I have added this to my list to look at.

[dc42]

@argo have you tested the behaviour in RRF 3.4.0beta7 ?

[Argo]

@dc42

I just did. The M291 messages do not cause the issue anymore.

[dc42]

@argo thanks. Thanks to your example I found another bug, which is that if a macro contains a non-blocking M291, some motion and then a blocking M291, with no M400 or G4 between them, then the blocking M291 can appear ahead of the non-blocking one and then you can't cancel the blocking one. This is fixed in the forthcoming 3.4.0rc1. Please try 3.4.0rc1 when that is released.
