Voron 0 modify BED_SCREWS_ADJUST klipper macro

[DennisM]

Hi, quick question here.

Googling around doesn't seem to work for me here. I am trying to see if there's a way to modify the BED_SCREWS_ADJUST macro so that the bed will move away from the head after I'm done. I have to manually move the bed away after I finish the screw adjustments every time, so it would be nice if that happened automagically when I finished.

Any ideas? I can't find any existing macros for BED_SCREWS_ADJUST and/or how to add code that runs AFTER I hit the "finish" button on my KlipperScreen.

Have you looked at the Klipperscreen Docs?

This might not answer your question but... it does cover a lot.

I did read through:

https://klipperscreen.readthedocs.io/en/latest/Panels/Screws/

But didn't see much in the way of post-leveling macros or a way to initiate commands like bed moves.

One option might be for me to make a macro to move things to where I'd like them to be and somehow see if I can add a "quick-access" button on the left side of the Klipperscreen for easy access.

Sounds like it might be worth a try. 

TBH, the whole klipperscreen thing is cool and all my printers have them, but it would be a lot better if we had a less convoluted way to edit its functionality. Or maybe there is, and I don't know.

This is easy, make a new macro called "my_new_improved_bed_leveler".  it has only two lines: (1) BED_SCREWS_ADJUST and (2) a "G0" command to move the print head.

 

It is odd that you did not find out how to move the bed.  It is the first "g code", g-zero.

Hi, thanks. Of course I know how to move the bed and nozzle via G0/G1 commands, that wasn't the question.

But I like the idea of the new macro, replacing the original. Here's a draft of what I'll tinker with:

[gcode_macro BED_SCREWS_ADJUST]
description: Bed screws adjustment then move bed away from nozzle
rename_existing: BED_SCREWS_ADJUST_ORIGINAL
gcode:
    BED_SCREWS_ADJUST_ORIGINAL
    G90                    ; absolute positioning
    G0 X60 Y110 Z8 F2000   ; move nozzle to back center and lower bed

Nope, that attempt didn't work. The printer function operated exactly the same with no movement afterwards.

Back to the drawing board.

My next attempt will be to try creating a new macro that does this and then invoking it from the macros menu. Not a preferred solution but I'll see if it works at all.

I have to give a +1 on this. There are so many great tools but they are too hidden away from the user. I've had other features that I would like to customize but I can't find any documentation on how they are actually implemented and I don't want to have to rely on Discord just to find out if it's even possible.

The problem is that you have attempted to redefine BED_SCREWS_ADJUST.     You can do this but the LAST definition of the macro is what has an effect.     I bet you defined your new macro BEFORE the original one was defined.

 

This is why I suggested calling your new macro by a new name as there would be no chance of this happening You could define it anyplace, order is unimportant

Try this...

 

[gcode_macro MY_NEW_BED_SCREWS_ADJUST]
description: Bed screws adjustment then move bed away from nozzle
gcode:
    BED_SCREWS_ADJUST
    G90                    ; absolute positioning
    G0 X60 Y110 Z8 F2000   ; move nozzle to back center and lower bed

Hmm, interestingly when I make a custom macro as discussed, I get an unexpected result:

1. Select macros on the menu
2. Pick the new macro name to run it
3. KlipperScreen shows a popup yellow box with "BED_SCREWS_ADJUST" in it and doesn't do anything at all.

Interesting... I'll dig a bit deeper.

[DennisM]

OK, so here's what's happening now and I don't think there's an easy way to fix this.

With a new custom macro, I can pick it from the menu and run it. But here's what it does:

1) The nozzle and bed move like they are going to let me start the adjustment process

2) Once the nozzle and bed are done moving, it then moves to my final position as defined in the custom gcode.

It's like the call to BED_SCREWS_ADJUST doesn't actually let it run for me, instead it just assumes it's done and then finishes the macro.
