Unsolved Issues with macros halting the printer.

[brunofporto]

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

M104 S210		; Set nozzle to 210 and release

M116                    ; Wait for all to heat

M292

M98 P"0:/macros/Center_Nozzle"; move to center of bed

M291 P"Nozzle will now move to center of bed to reset Z0 and calibrate probe" S2

G31 Z0				; Reset zprobe trigger height

M98 P"0:/sys/m_set_low_speeds.g"     ; set lower Z speeds and accelerations

M98 P/MACROS/SUBMACROS/BEEP.G

M291 P"Jog the Z Axis until the bed and nozzle are touching and click OK" R"Setting Z=0" Z1 S2

G92 Z0			; Set z = 0

M291 P"Probe will now measure trigger height 10 times" R"ZProbe Trigger Height Calibration" S2

M98 P"0:/macros/Center_Probe"   ;0 move to center of bed

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

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.

[brunofporto]

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?

[dc42]

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?

Thanks. I can see two odd things in that report:

http is doing "M291 P"Please wait while the bed and tool is being heated up" R"Please Wait" S1 T0 " in state(s) 0 0

It is still waiting for the M291 message box to be acknowledged, as if it hasn't received M292. So sending M292 should get it running again.

Scheduled moves: 35, completed moves: 36

Doing one more move than was scheduled doesn't sound right. But I don't think this is part of the problem you are seeing.

I'll review the M292 handling and see if there is any way that a M292 command might be missed.

[brunofporto]

@dc42 Thanks!

I am not sure when this issues started (I think it is with this latest 2.02 series of betas and RCs) but I did not have them before with the same macros.

For now I'll just comment all non critical M291 from these macros

[brunofporto]

@dc42 Same issue with RC5 - not using M291 S0 T0, swapped all of them to S1. The first M291 S1 message does not even appear.

If it doesn't appear, no wonder it gets stuck! It's waiting for the M292 command to be returned from DWC to tell it that you have acknowledged the message box. I can't think why it wouldn't appear, other than a network issue. Does your system have a PanelDue, and if so does the message box appear on it?

[brunofporto]

@dc42 Yes I have a PanelDue. No... it does not appear there even when the macro is executed from PanelDue.

Same behavior as DWC: Right after resetting the macro works (it halts at the end of the macro but works until that). But If I execute anything before it (like a G32) it does halt after the first M291 S3 as Busy and does nothing.
