Issues with macros halting the printer.

[brunofporto]

This issue is happening with filament and other macros as well.

I have a nice Z-probe calibrating macro but if I execute it right after resetting the Duet it works. If I execute it again or after other macros execution it just set the printer as "busy" and does nothing at all.

If I execute it line by line it works fine and without issues.

To try to find the culprit I chopped the macro into several short macros... But the issue is happening right at the first test!!

The test Macro is as follows:

M291 P"Please wait while the bed is being heated up" R"Please Wait" S0 T0 ; Display message
M140 S60 ; Set bed temp to 60
G32 ; Home all axis
M116 ; Wait for heating
M292 Close message
M291 P"Please wait while the bed is being heated up" R"Please Wait" S3 T0 ; Display message
M98 P/MACROS/SUBMACROS/BEEP.G

Now... If I execute this simple macro right after resetting the board then it works flawlessly... But If I execute it right after that it just set the printer as Busy and does nothing at all. I do not heat the bed or show any messages.

I am having this issue with my filament macros, any macro that uses M292 to show any messages. Not sure when it starts having issues but the latest two RC firmware has the same issue for sure.

Thank you.

ok... Pinned down the issue when using M291 with the parameter S0 - If I do not use S0 (using S1 instead) then the issues of halting the printer without doing anything does not happen.

Nope... happened again even with all S0s as S1s

Can you post your homeall as well? Would help to see what is happening when you call g28

[dc42]

Please tell us which firmware version you are using, and try 2.02RC4 if you are using an older version.

[brunofporto]

@dc42 I have this issue at least since 2.02RC3 at least (not sure about earlier betas). Currently with RC4.

[dc42]

Please provide the contents of beep.g too, and I will try those macros out on my printers.

Just now. Turned on the printer. Did a G32 command (bed.g attached) and clicked at the Z Probe calibration macro (below). And.... Busy doing nothing.....

Just to reinforce: This "busy halt" does not occur if I execute the macro line by line at the console.

Here is the macro:

M291 P"Grid bed compensation map and ZProbe trigger height will be cleared. Ok or Cancel?" R"WARNING" S3 ; User must click OK or cancel.

M561			; Disable any current bed compensation

G29 S2			; Clear mesh bed compensation perameters

M291 P"Please wait while the bed and tool is being heated up" R"Please Wait" S1 T0 ; Display message

M140 S60		; Set bed temp to 60 and release

G32			; Home all axis

M116                    ; Wait for bed heating

Just a reminder that I asked yesterday for your beep.g macro too.

[brunofporto]

@dc42 Here it is!

By the way... I cannot play any "tunes" without adding these timers between each M300. At least with the PanelDue attached.

M300 S2000 P300
G4 P300
M300 S2000 P300
G4 P300
M300 S2000 P300

PanelDue has no flow control, deliberately to avoid holding up the Duet. But I could implement a short queue of beeps pending in the PanelDue firmware.

I'm sorry, I can't reproduce the problem using either your test macro or the full macro (I had to make up the contents of 4 more macros thai it called).

By the way, your test macro is missing a semicolon before the comment "Close message" on the M292 line.

How reproducible is the problem?

My best guess as to why it is hanging is that when you cancel the M291 message box, the M292 command to tell the Duet that it has been cancelled is not being received and/or processed. So I have two suggestions:

1. Connect a PC running YAT or Pronterface etc. and send M111 S1 P3 to enable GCodes debugging. Then you will be able to see whether the M292 command is received.

2. Next time it appears to be stuck, try sending M292 and see whether that un-freezes it.

Just happened again...

Freshly started board.

G32

Sent the macro from the 22/11/2018 message above. Appeared the messages informing that the bed and hotend would be heated. Clicked ok and.... halted.

[dc42]

So did you try my suggestions?

[brunofporto]

The complete sequence and used files:

Sent G32 and waited for it to finish:

Executed the Macro:

Clicked ok and then.... halted doing nothing:

Attached bed.g, calibration macro and all sub macros related.

Thanks.

[brunofporto]

@dc42 I'll..... But the printer is far from a computer and heavy...... As soon as I am able to move it and connect an USB directly I'll try

[brunofporto]

@dc42 Please, in order to avoid moving it unnecessarily, is it possible to monitor via telnet or something?

Yes, use the M586 command to enable Telnet.

ok.... It receives the M292 command, confirms it, but the printer still busy doing nothing

Can you send M122 and get a report?
