How to pause a program/macro?

handyandy

I am trying to write a program/macro to make determining the trigger height of my IR Z probe easier. At the moment I enter each of the following lines manually...

M561;cancel any previous
M208 S1 Z-3; allow extra Z beyond home
G0 X140 Y105; position to centre of bed
G91; set relative mode
G1 Z-0.02; I repeat this move as necessary to just grip paper between bed and nozzle
G92 Z0; sets the final position as Z0
G90; set absolute mode
G1 Z5; up 5mm
G30 S-1; probe the bed and read off the trigger height from machine status Z value

Ideally I would like to write a program for this that pauses operation after the G91 so that I can enter G1 Z-0.02 manually into the command box and send it as many times as necessary then somehow resume the code.
I don't want to use pause.g or resume.g for this.

@handyandy I've never used it myself but I see that M291 (Display message and optionally wait for response) now has the option to display jog buttons to quote "allow the user to adjust the head position on the specified axis". https://duet3d.dozuki.com/Wiki/Gcode#Section_M291_Display_message_and_optionally_wait_for_response

So, possibly you could use M291 after your G91 and before your G92 Z0. Maybe with the S2 parameter and Z1 which, if my understanding is correct, ought to bring up the jog buttons . Having never used it, I don't know what resolution the jog button will give you and/or whether that can be set to 0.02.

Edit. Or simply use M291 to give you the message box in "blocking mode", then adjust the Z height as you do now, then press enter or use M292 to resume the macro.

Unfortunately that does not work. It just stops the program but does not allow any user inputs whilst stopped. Press ok and it just continues.

Apologies - That does work! I was just putting Z and the line end and not Z1
Thanks alot

Oh brilliant! Hoped it would work but it's not something I have personal experience of using. Is that using the jog buttons? If so, what resolution does it give you for jogging Z?

Edit - or does it just allow you to use the "normal" jog buttons that DWC and/or panel due provide?

It will give you separate jog buttons included in the dialog that share the resolution of the normal ones. Only thing is that you cannot change the values in the dialog so the resolution must be set beforehand.

EDIT: Just run

M291 S3 Z1 R"Jog Buttons" P"Give me jog buttons!"

and you'll see. It won't bite.

EDIT2: If necessary you can even get jog buttons for as many axes as you like. Just add the appropriate axis names to the command (each followed by the number 1).

@wilriker For info, I do use M291 a lot - just never used the jog buttons before. I would have tried it but for reasons other than fear of being bitten, I am unable to do so right now

Edit..........but thanks for confirming that the resolution of the jog buttons is inherited from DWC.

Hi!
This is really a nice thing with the query pops. What I unfortunately find very bad about the jog buttons is the division 0.05 >0.5,... better would be 0.01>0.10,..,

On my PanelDue 7i completely different values are displayed 0.02>0.2,... The buttons don't work.
Firmware 1.22.1(28b1).
In the browser the buttons work as they should.
What is the reason for this?
Is there also a possibility to say in the dialogs go to line,... I have a huge collection of macros, but I only checked a few.

Sorry about my bad English!

As I mentioned above you can configure the values of the jog buttons. Though not inside the dialog. Just go to the normal jog buttons on the Machine Control tab and right-click them. This will open a dialog to enter a new value for this button (and its corresponding +/- button). The buttons in the M291 dialog share the same values.

If you are happy with the values you have to save them via Settings -> Apply Settings or they will be lost upon reload of DWC.

As to your PanelDue question I am out of that because I don't have a PanelDue.

GaryK

Thanks for the info! I didn't know this feature yet. Maybe there is a manual for the Panel Due. I must say that I own my board only since last week and I am enthusiastic about it.
I just tested something and changed the jog buttons in the browser.
On the panel only the values of X and Y are taken over. At Z are the 0.5,... steps still available. In the Jog menu under the tab "movement", the buttons work however as already mentioned with Z 0.05 although 0.01 was set.
Seems to be a bug?
The bug is known see also:

Sry!

I've found that if you start a macro on the DWC, the jog buttons that show up on the panel due will not work. However, if you start the macro on the PanelDue, they will. Also, it doesn't seem like the PanelDue movement increments are obtained from the DWC. If I start the macro from the DWC, the job buttons will take their resolution from the DWC settings, but the Panel due will still be 0.2, 2, etc.

That sounds like a bug.

But that sounds normal/expected since DWC and PanelDue are completely separate communication channels to the Duet. I think they don't even know about each other's existence.
