Hide macros, outputs or fans

Macros can be hidden directly from the interface in the macro settings.

You can also hide them and other devices by prefixing the name with an underscore.

Lets hide a temperature_fan:

[temperature_fan fan1]
[temperature_fan _fan2]

fan1 will show in the interface, but _fan2 will be hidden.

Layer Progress

Accurate layer progress as a message below the status:

• PrusaSlicer
• Cura
• ideaMaker

PrusaSlicer

• Open PrusaSlicer
• Go to: Printer Settings > Custom Gcode > After layer change Gcode
• Add this:

M117 Layer {layer_num+1}/[total_layer_count] : {filament_settings_id[0]}

Cura

Install the extension: Display Filename and Layer on LCD

IdeaMaker

• Open IdeaMaker
• Got to: Slice > Manage templates > Click on your template > Edit
• Select the tab named Gcode > Layer Change Gcode
• Paste this:

M117 Layer {layer_index} / {total_layers}

Accurate layer progress in the secondary screen of the printing panel:

• PrusaSlicer
• Cura
• ideaMaker

The layer number in the secondary screen of the printing panelis calculated according to object height and provided layer height. It will be innacurate when using variable layer height, but can be fixed by providing klipper with the correct data.

PrusaSlicer:

• Open PrusaSlicer
• Go to: Printer Settings > Custom Gcode > Start Gcode

SET_PRINT_STATS_INFO TOTAL_LAYER=[total_layer_count]

Printer Settings > Custom Gcode > After layer change Gcode

SET_PRINT_STATS_INFO CURRENT_LAYER={layer_num + 1}

Cura

Cura doesn't have a way to use this directly (the only "g-code on layer change" post-processing plugin doesn't support variables), so the only way to work around is by adding a replacement post-processing script and a specific macro to Klipper.

To add the script to Cura, use the following steps:

• Open Cura
• Open the Extensions menu, then Post processing, and click on Modify G-Code
• Click the Add Script button, and select Search and Replace from the options
• On the Search textbox, enter this:

;(LAYER|LAYER_COUNT)\:(\d+)

• On the Replace textbox, enter this:

;\1:\2\n_CURA_SET_PRINT_STATS_INFO \1=\2

• Tick the Use Regular Expressions checkbox
• Click Close

In Klipper, add this macro to your printer.cfg:

[gcode_macro _CURA_SET_PRINT_STATS_INFO]
gcode:
  {% if params.LAYER_COUNT is defined %}
    SET_PRINT_STATS_INFO TOTAL_LAYER={params.LAYER_COUNT}
  {% endif %}
  {% if params.LAYER is defined %}
    SET_PRINT_STATS_INFO CURRENT_LAYER={(params.LAYER | int) + 1}
  {% endif %}

Then save the changes and restart Klipper.

After this, any new file sliced in Cura will tell Klipper how to handle the layer values

IdeaMaker

• Open IdeaMaker
• Got to: Slice > Admin templates > Click on your template > edit
• Select the tabs named Gcode > Layer Change Gcode
• Paste this:

SET_PRINT_STATS_INFO TOTAL_LAYER={total_layers}
SET_PRINT_STATS_INFO CURRENT_LAYER={layer_index}

Note

{total_layers} doesn't seem to be available in the Start gcode (at least on IdeaMaker 4.3.2)
