[SOLVED] M0 Pause (far!) too short

Hi,

I have to print things on an old ordbot hadron running marlin 2.0 and need to pause at some layer (say 120 for example) to insert a nut.
Cura 4.8.0 on Ubuntu 20.04 are my slicer/OS.

Here attached the "Pause at height" cura setup.


Here's the g-code cura's been generating accordingly.

;added code by post processing
;script: PauseAtHeight.py
;current layer: 120
M83 ; switch to relative E values for any needed retraction
G1 F300 Z14.4 ; move up a millimeter to get out of the way
G1 F9000 X190 Y190
G1 F300 Z15 ; too close to bed--move to at least 15mm
M104 S0 ; standby temperature
M117 Paused
M300 S440 P200
M0 ; Do the actual pause
M109 S240 ; resume temperature
G1 F300 Z14.4
G1 F9000 X103.797 Y100.097
G1 F300 Z13.4 ; move back down to resume height
G1 F1500 ; restore extrusion feedrate
M82 ; switch back to absolute E values
G92 E205.97136
;LAYER:120

When the moment comes to pause, the head moves to 190x190 as expected, beeps are heard and... immediately the print is resumed before I can insert the nut, that is: no pause happens at all.

I know I can split the gcode file, etc, etc. That's not what I'd like to experience, but have a few seconds, i.e the time needed to place the nut and then press the resume button to get the print back at work.

I did try to specify 1800 as "disarm timeout" for no more luck.

What can I / do I have to do to sort it out?
Thanks

... hmmm ... a time set of "0s" isn't this long - or is it?

M0 ; Do the actual pause

Have you tried setting the S Parameter to M0?

Hi, thanks for contributing.

@VDX, as I mentioned 1800 set as "disarm timeout" changes nothing.

@cqexbesd nope!
This code is generated by cura and directly sent to the printer via USB. I'm not using a SD card. I'll give it a try and tell you back.

BTW I’m using M125 P1 do achieve something similar.

OK, as you can see in my 1st post, cura's post processing plugin has an option for the "Pause at height" method.

You can find here:
* Marlin (M0)
* Griffin (M0, firmw...
* BQ (M25)
* RepRap (M226)
* Repetier (@pause)

As Marlin is the firmware loaded in this printer, I reckoned Marlin (M0) would be the appropriate choice.

No M125 P1 method shown here.

It works. I edited the gcode file produced by cura, replacing the line

M0 ; Do the actual pause

by

M0 S120 blabla; Do the actual pause

and submitted it to the printer.

I guess I could try to use the "Search and Replace" cura extension to do the job... I'll give a try some time.

Thanks you all for the help.
