moving the points for z-tilt

Ahhh thank you. That was what I was searching for. TBH it was 2 in one question. First of all if it is correct and 2nd how it is defined right now. This is the config for the 500: points: 30,30 250,460 470,30 Means the actual points are 30mm from the edges. And my suggestion is 50mm off the edges. Ok thx 🙂

How to limit the part cooling fan max power on IDEX printers?

its a personal workaround. its more likely to use equal settings on all printers. and thats why i limit the max power to have similar settings for the printers while using the same filament. its just a personal thing.

How to limit the part cooling fan max power on IDEX printers?

Yes, if you can tell me what it is, then I am happy. I just found the section part cooling in the files provided by RatOS and that’s why I use the expression [fan] the same as in the Klipper documentary

How to limit the part cooling fan max power on IDEX printers?

from another server i got a solution to include a part cooling overwrite: https://github.com/charredchar/Klipper-Macros/blob/main/part_cooling_override.cfg however, i dont want to include macros i dont understand.

[gcode_macro M106]

    {% set vars = printer["gcode_macro M106"] %}
    {% if vars.manual_fan == 0 %}
      {% if 'S' in params %}
        {% set speed = params.S|float %}
        {% set adjustedS = speed * offset_percent|float %}
        {% if adjustedS > vars.max_fan %}
          {% set adjustedS = vars.max_fan %}

unload macro moving out of range

so, the solution is: always M84 (turn off the motors) after set kinematic position

unload macro moving out of range

yes, i am aware of that. i guess the error came because the M84 was not done before doing anything else. set kinematic position was just the fastest way to move the bed down.

Mirror/Copy mode and cancel print not working

could maybe considered as a feature for a future updated RatOS. but i guess the priority is very low for this kind of feature. firstly we have to eliminate all bugs 😉 and i probably found another one which will be discussed in another post.

Mirror/Copy mode and cancel print not working

everything works now how it should. so the variable is now fixed and you can use it with a primeblob and without. everything is now how it should be according to the guide: https://os.ratrig.com/docs/configuration/adaptive-meshing/#adaptive-prime-blob-configuration

Mirror/Copy mode and cancel print not working

Solution for the IDEX 500 Copy/mirror mode issue for RatOS 2.1.0 RC3: - include this file into printer.cfg - set variable_nozzle_priming to False --> the printer will print without a primeblob. --> set the variable to "Primeblob" and it will do the primeblob bug fixed.
