M291 messages are not always displayed in macros

Aitor

Good morning,

I am on PanelDue version 3.2.11 some messages M291 S3 and M291 S4 are not displayed when running them from macros in PanelDue, but in the browser.

I have tried to put in front and behind M400 but I have not achieved that they are shown.

On the other hand, is there any command that I can send so that the LCD shows me the CONTROL window for example, as PRINT is shown when I give it to print, I have the feeling that this will solve it because if I run the M291 commands from the browser if they are displayed.

thanks

What duet firmware and DWC version are you using?

Good morning @phaedrux ,

I have tested with DWC 3.2.2 and 3.3RC1

Anyway I got confused yesterday, it's the messages M291 S0 and M291 S1 that don't work the S2 and S3 take a while to come out but they end up coming out.

Ok. The behavior is a little unexpected

running a script with only M291 S0 -> message is displayed
running a script with only M291 S1 -> message is displayed
running a script with only M291 S2 -> message is displayed
running a script with only M291 S3 -> message is displayed
running a script with multiple messages M291 S0, S1, S2, S3 -> only S2 and S3 messages are displayed.

I think the reason is that PanelDue does not buffer messages, so only the latest message is shown. This means that if a message does not require acknowledgement, the script that generated it is not suspended; so if it goes on to generate a new message, that message will overwrite the previous one.

Good morning @dc42 ,

In panel due version 1.24 or 1.23 (I don't remember) it worked correctly.

@mfs12 indeed I have two messages in the same script, with what you tell me I will do some more test, to see if I can leave it in a single message or run the messages from another script using M98, to see if this works.

@aitor there was a change to RepRapFirmware several versions ago. Several users complained that when the printer started up, the informational messages shown on PanelDue slowed down the startup sequence, because each message had to time out before the next one was shown. So we changed RRF to not buffer up messages, but instead allow later messages to overwrite earlier ones.

@aitor said in PanelDue V3.2.11 M291 S3 and M291 S4 are not displayed:

Good morning @dc42 ,

In panel due version 1.24 or 1.23 (I don't remember) it worked correctly.

@Aitor I think it was 1.24. This was the version i did initial testing.

@Aitor would you be interested in testing if you issue persists with new versions of RepRapFirmware and PanelDueFirmware?

Check here for firmware files:

Good morning @mfs12,

Unfortunately the S0 and S1 messages are still not displayed when there is more than one, I have tried to launch this code, in several situations

If I run the macro from the web control, the messages are shown both in the panel due and in the web control.

If I run this macro from the due panel, only the messages S2 and S3 are shown in the panel due and all in the web control.

I have also been able to verify that if I run this macro from web control when the Screensaver is active, the messages are displayed (slow) but also when the Screensaver is finished it is blocked and does not let me control the panel due for a long time (more than 2 min), this also happened to me during a print when the filament detector jumped, in this message also shows a message M291 S3 and I think that is what blocked it, on that occasion I had no patience and restarted the printer.
Attached is a video to show the problem with Screensaver

The tests have been done on two machines both in these versions but different panel due

Board: Duet 2 WiFi (2WiFi)

M291 R "3. OK and Cancel" P "3. OK and Cancel are displayed (blocking, send M292 to resume the execution or M292 P1 to cancel the operation in progress)" S3

I would be happy to carry out further tests, thank you.

Best regards

@aitor thanks for the detailed description and the video.

About the S0 und S1. If multiple messages shall be displayed only the latest one is shown.

This was a design decision. So I can't do anything immediately about it. But if you want it blocking you could use S2 message, but with the downside the it will stop your script.

About the screensave issue. This looks like a bug, later today i will try to reproduce on my setup and will keep you updated.

Good morning @mfs12,

Yes it was clear to me that this was not going to be shown, but as you mentioned to try it I couldn't avoid it, besides I still don't understand very well why this was done, I don't see any sense in it, as a solution I use M118 this way:

M118 P0 S"0. No buttons are displayed (non-blocking)" L0
M291 R"0. No buttons" P"0. No buttons are displayed (non-blocking)" S0
M300 S300 P1000
G4 S5
M400
M118 P0 S"1. Only Close is displayed (non-blocking)" L0
M291 R"1. Only Close" P"1. Only Close is displayed (non-blocking)" S1
M300 S300 P1000
G4 S5
M400
M291 R"2. Only OK" P"2. Only OK is displayed (blocking, send M292 to resume the execution)" S2
M291 R"3. OK and Cancel" P"3. OK and Cancel are displayed (blocking, send M292 to resume the execution or M292 P1 to cancel the operation in progress)" S3

On the other hand this other code doesn't work for me, but I don't know if I'm using it right, I understand that when using M118 P2 only the message should be shown in the panel due right? but they are not shown and in case 1 if, I understood it right? or I'm using it wrong? (in version 3.2.11 it didn't work either):

M118 P2 S"0. No buttons are displayed (non-blocking)" L0
M291 R"0. No buttons" P"0. No buttons are displayed (non-blocking)" S0
M300 S300 P1000
G4 S5
M400
M118 P2 S"1. Only Close is displayed (non-blocking)" L0
M291 R"1. Only Close" P"1. Only Close is displayed (non-blocking)" S1
M300 S300 P1000
G4 S5
M400
M291 R"2. Only OK" P"2. Only OK is displayed (blocking, send M292 to resume the execution)" S2
M291 R"3. OK and Cancel" P"3. OK and Cancel are displayed (blocking, send M292 to resume the execution or M292 P1 to cancel the operation in progress)" S3

I will be attentive to the updates that you make and I will comment you if I find something else.

Thanks and best regards

Hey @aitor, well so i could reproduce your problem. I simplified your script to a bare test case. It would be nice when you could confirm that they reproduce the faulty behavior on your device.

If you check the attached macros

without M292 command message is displayed test-m291-s1-ok.g
with M292 command message is not displayed test-m291-s1-fail.g

Aitor

Good morning @mfs12,

I have already tested as follows

Running the macros from PanelDue:
test-m291-s1-ok.g
It shows (but takes a little while)
test-m291-s1-fail.g
Not shown (I assume that this is normal, as mentioned above)

Running the macros from ControlWeb without the Screensaver:
test-m291-s1-ok.g
The message was displayed (a bit faster)
test-m291-s1-fail.g
Not displayed (in my tests it did display because of giving it more time between messages, my Z-axis is quite fast)

Running the macros from ControlWeb with the Screensaver active:
test-m291-s1-ok.g
The message takes a while to display, and lasts less than a second on screen, then it is hidden behind Screensaver (clicking on Screensaver shows the message, but it is not automatically disabled as it was in previous versions), Screensaver is not blocked.
test-m291-s1-fail.g
Not shown at any time, Screensaver remained active but did not crash

These were my results, to replicate the Screensaver error, I don't think these macros will help you.

Best regards, thanks

mfs12

Hey @aitor, also could reproduce the screensaver bug.

Thanks for reporting both issues. I created to issues:

M291 S0 and S1 issue https://github.com/Duet3D/PanelDueFirmware/issues/146
M291 S3 and S4 screensaver issue https://github.com/Duet3D/PanelDueFirmware/issues/147

Any update concerning this problems will be reflected in the gitlab issues.

mfs12 created this issue in Duet3D/PanelDueFirmware

closed M291 S0 and S1 are not displayed when M292 follows #146

mfs12 created this issue in Duet3D/PanelDueFirmware

closed M291 leads to unresponsiveness when screensaver is activated #147

Hey @Aitor, i think i found the issues. I build a test release. Would be cool if you could test them and provide feedback. If positive I am going to build another release candidate.

Check the attached image file.

@Aitor weird enough... so far this fixes only the screensaver bug. The other one persists. When i was testing it it appeared ok, but i was wrong!

Aitor

Good morning @mfs12

Running the macros from PanelDue:

M291 S0 and S1 messages are not shown, this is fine according to what we have discussed.
M291 messages S2 and S3 are displayed normally.

Running macros from ControlWeb without the guard:

M291 S0 and S1 messages are displayed but very late, I had to switch from G4 S5 to G4 S10 to get the messages displayed

M291 messages S2 and S3, displayed normally.

Running the macros from ControlWeb with Screensaver active:

The Screensaver is not blocked, so it works correctly, the message is not hidden and Screensaver is not deactivated, it behaves like "Running macros from ControlWeb without the screensaver" but with the Screensaver active at all times, I do not dislike this behaviour,but this is my opinion.

The Screensaver bug is fixed, I will do more tests if I find something and let you know.

I'll be happy to do more tests, let me know with anything, I'll be happy to help in any way I can.

By the way, if something is not well understood tell me, it may be a bad translation.

Best regards and thanks

Aitor

Good morning @mfs12

I hadn't read your last message, as far as I've been able to check it's a timing thing, since version 3.2.9 which is the first one I tried since "3.1", I've noticed that the messages are a bit slower.

As I don't know about programming I can't know why.

Best regards

mfs12

@Aitor thanks for testing.

I had deeper look into M291 S0 and S1 issue and this seems to be more complex. So let's see how long i twill take to fix that. The only workaround so far is to avoid M292 gcodes in scripts.
