Bed Tramming from the LCD

Macros
1

I wanted to be able to use my Z probe to tram the bed and tell me how to adjust the leveling screws all from the LCD without having to use the computer. I finally got it working, and here’s a video of it in action.

As of 2/3/2023 (commit fa78e6b), this solution works on mainline Klipper without the need for any code patches. To get started, create a new screws_display.cfg containing the following:

This also requires a custom menu.cfg to override defaults. I was already using a custom menu from this thread. Here’s my new menu.cfg with the bed-tramming additions:

    SET_GCODE_VARIABLE MACRO=GLOBALS VARIABLE=display_group VALUE="'_default_16x4'"
    {(menu.exit(true))}
index: 1

Finally, some macros need to be added to printer.cfg:

This one is a hack to store a variable that is used to keep track of what menu structure to display.

[gcode_macro GLOBALS]
variable_display_group:"_default_16x4"
gcode:
    M115 ; must provide something

This one will home all axes that aren’t already homed. This isn’t strictly necessary but it saves time when repeating the measurements.

[gcode_macro SMART_HOME]
gcode:
    {% set toHome = [] %}
    {% if 'x' not in printer.toolhead.homed_axes %}
        { toHome.append('x') or "" }
    {% endif %}
    {% if 'y' not in printer.toolhead.homed_axes %}
        { toHome.append('y') or "" }
    {% endif %}
    {% if 'z' not in printer.toolhead.homed_axes %}
        { toHome.append('z') or "" }
    {% endif %}
    {% if toHome|length == 0 %}
        { action_respond_info('All axes homed!') }
    {% else %}
        G28 { toHome|join(' ') }
    {% endif %}

This one is the magic.

[gcode_macro TRAM_BED]
gcode:
    SET_DISPLAY_GROUP GROUP=screws_running
    SET_GCODE_VARIABLE MACRO=GLOBALS VARIABLE=display_group VALUE="'screws_running'"
    SMART_HOME
    screws_tilt_calculate
    {% if printer.screws_tilt_adjust.error %}
        SET_DISPLAY_GROUP GROUP=screws_error
    {% else %}
        SET_DISPLAY_GROUP GROUP=screws_results
        SET_GCODE_VARIABLE MACRO=GLOBALS VARIABLE=display_group VALUE="'screws_results'"
    {% endif %}

This should work with any bed that has 4 leveling screws. It should also work with 3 screws as long as the third screw (the “middle” one) is on the side of the bed opposite the X endstop and has a Y location roughly half way between the other two screws. In other words, on an otherwise stock Ender 3 that’s been converted to three bed screws, if there are two screws on the left and one on the right, this should work.

I know this is an old post but I love this! How do I get this to properly work on a 4 screw bed? I tried adding some screws in the screw_display.cfg but it seems to only want me to adjust 1 screw. Thanks in advance

Got it working for the most part. Only thing left to figure out is why Base is not showing.

Which screw is your base screw and what is the display showing instead?

5

Base is back left. Its showing nothing right now.

Thanks for the help

In your “BACK LEFT” block, this line shouldn’t be commented out:

#[display_data screws_results back_left_sign]

7

So it was! Thank you! An extra set of eyes is great to have! Works perfectly now.

This commit breaks the results screen, screws_tilt_adjust: status result as dictionary · Klipper3d/klipper@fa78e6b (github.com)

I loved doing this via the LCD but I don’t understand what’s changed in this commit to make necessary adjustments.

9

I knew this was coming. I’ll plan to update the macros to be compatible with mainline Klipper, but I’ll need a tester as I’ve since migrated to KlipperScreen.

If you do it, I’ll be up for testing.

11

Does your machine have 3 or 4 leveling screws?

12

4, I used rick88Mustang’s modification above.

13

All right, I’ve updated the original post to reflect the updated code and instructions. @Kaan tested this and it’s working with 4 bed screws. Ironically, I’m not using the stock LCD on my own printer anymore so I haven’t been able to test with my original 3-screw setup, but it should work just the same.

14

I created the new cfg files and put the new macros in printer.cfg and the menu shows on my 12864 screen but nothing happens when i select tram bed and i get this error.

15

What happens if you issue a simple SCREWS_TILT_CALCULATE gcode command?

16

I get "Unknown command:“SCREWS_TILT_CALCULATE”
menu.cfg (4.7 KB)
screws_display.cfg (11.2 KB)

17

This guide assumes your printer is already properly set up for probe-based tilt adjustment.

18

Ahhh got it thanks!

19

Added the required Screws_tilt_adjust code in the cfg and this now works perfectly.

thank you very much!
