IDEX Toolchange Fan Control



  • Hello,
    I have a fan control problem on my IDEX Printer. In tfree0 and tfree1 I have add the command M106 S0 so that the Fans are switched off when the Tool is not used.
    In tpost0 and tpost1 there is M106 R2 to switch the Fan on again when the Tool is active.
    If the respective Tool is active, the Fan do not switch on.
    In Simplify3D I have set the Fans should run from the 3rd Layer.
    Why don't the fans Start?

    Thanks for your help

  • Any Idea?

    Can you include your tool change files and a sample sliced gcode file?

    @gringo said in IDEX Toolchange Fan Control:

    In tfree0 and tfree1 I have add the command M106 S0 so that the Fans are switched off when the Tool is not used.
    In tpost0 and tpost1 there is M106 R2 to switch the Fan on again when the Tool is active.
    If the respective Tool is active, the Fan do not switch on.

    So what I think is happening is that you are turning the fan off and then asking it to resume to the last set speed, which was off, so it's staying off.

    Does that make sense?

    Rnnn Restore fan speed to the value it has when the print was paused (R1) or the last time the fan speed was set and no P parameter was provided (R2).

    At least that's my reading of what R2 does.



  • I think so too.
    But if I want the Fans off for the first 2Layers. How do I Adjust that?


  • Moderator

    Can't you add a gcode process in s3d for that layer?



  • I have now set a fan speed for Layers 1, 2 and 3 of 1%, 50% and 100% in S3D.
    I let Tool 1 heat up first, so it works now.
