Hi @ianalexis, thanks for offering to include this!

My proposal is to update the Wiki examples for M106/M107 so that fans can be mapped by both index and name. This way users can still use M106 P0, M106 P1, etc., but also reference the fan by the name they assign in their config (e.g., CPAP, EXHAUST).

Example implementation:

[fan_generic CPAP] #fan 0 orcaslicer
pin: PB7
max_power: 0.8
shutdown_speed:0
kick_start_time: 0.100
cycle_time: 0.005
hardware_pwm: False
off_below: 0.10

[fan_generic EXHAUST] #fan 3 Orcaslicer
pin:PE5
#max_power:
#shutdown_speed:
cycle_time:0.01
hardware_pwm:false
#kick_start_time:
off_below:.2

[gcode_macro M106]
description: "Set fan speed (Orca compatible)"
gcode:
{% set fan_map = {
0: "CPAP", # Orca P0 → CPAP blower
3: "EXHAUST", # Orca P3 → Exhaust
} %}
{% set p = params.P|int if 'P' in params else 0 %}
{% set fan = fan_map[p] if p in fan_map else "CPAP" %}
{% set speed = (params.S|float / 255 if 'S' in params else 1.0) %}
SET_FAN_SPEED FAN={fan} SPEED={speed}

[gcode_macro M107]
description: "Turn off fans. No P = all, P# = specific"
gcode:
{% set fan_map = {
0: "CPAP", # CPAP blower
3: "EXHAUST", # Exhaust (or remap as needed)
} %}
{% if 'P' in params %}
{% set p = params.P|int %}
{% if p in fan_map %}
SET_FAN_SPEED FAN={fan_map[p]} SPEED=0
{% else %}
RESPOND PREFIX="warn" MSG="Unknown fan index P{p}"
{% endif %}
{% else %}
# No P → turn off all mapped fans
{% for f in fan_map.values() %}
SET_FAN_SPEED FAN={f} SPEED=0
{% endfor %}
{% endif %}

This allows more user-friendly naming while keeping backwards compatibility with M106 P# commands.
Hopefully this is what your requesting.

I made some changes and sent them to you via Discord to see if you agree before uploading them.

thanks for offering to include this!

Moved to #10369

I post it here even if offtopic: I was providing help on Facebook and I checked the Wiki. It looks amazing compared to few months ago, you (and everyone else who helped) did an amazing job!
Thanks.

I'll try to add some mention about the implications of various infill patterns over the layer time, as per #8107 (comment)
It does affect banding and differing shrinkage.

In which section should I put it?

Every pattern has it's own section here https://github.com/SoftFever/OrcaSlicer/blob/main/doc/print_settings/strength/strength_settings_patterns.md

Each pattern has some params:

- **Horizontal Strength (X-Y):** Low
- **Vertical Strength (Z):** Low
- **Density Calculation:**  % of  total infill volume
- **Material Usage:** Normal
- **Print Time:** Normal-Low
- **Material/Time (Higher better):** Normal-High
- **Applies to:**
  - **[Sparse Infill](strength_settings_infill#sparse-infill-density)**

Maybe you could add something like

- **Horizontal Strength (X-Y):** Low
- **Vertical Strength (Z):** Low
- **Density Calculation:**  % of  total infill volume
- **Material Usage:** Normal
- **Print Time:** Normal-Low
  - **Layer Time Consistency:** XXXX
- **Material/Time (Higher better):** Normal-High
- **Applies to:**
  - **[Sparse Infill](strength_settings_infill#sparse-infill-density)**

The issue is how to calculate this difference. To calculate the other values, I used that XLSX file where I automated the process by loading values from a standard part for each infill.
I don't know how we could do this other than by eye. If you want, talk to me on Discord and we can discuss it.

I'm slicing a cube 100x100x100 mm 20% infill and I check the variation in layer time. "none" is zero, "minimal" is few percent, "large" is more than 100%, then "low" for few tens % (think gyroid)

Here it is

Fantastic work! I will do an overall review of the Wiki content before I release the public 2.3.1 Beta.

Did you include my last file?

I didn't get to see it before they accepted the PR. I saw it and it looks good. I'm going to make some changes (to the xlsx and the file) and if you want, I can send you the files so you can upload your own PR, or if you prefer, I can upload it and list you as a co-author. Whatever you prefer.

I uploaded the file since I was the only one to modify it, now you can upload as part of your commit and list me as co author. Maybe two commits, one for mine and one for your changes on top, so I'll review them more easily.
