[Help request] Pressure advance compensation for cooling
-
So we have pressure advance compensation to compensate for the delay in extruding plastic, what do we have for the same issue with extruding cooling air?
Problem: when a machine starts spinning a motor, the result comes with a measurable and predictable delay.
The problem with extruding plastic is addressed and it is called "pressure advance compensation" or something like that.
Another problem: actually, it's the same problem, when a machine gets a command to start a cooling fan, there's a very noticeable delay for the fan to ramp up and then for the air to actually come out and start cooling stuff.Question: does a solution to this problem exist?
If so, what's its name and what am I supposed to do to turn a fan a second or two in advance of a bridge?
I am failing to find anything, search engines nowadays are not very helpful.
And I'm a bit tired of manually editing my gcode files. -

I know that Cura has an option for fan lag. It moves the fan command up by the lag amount so that it's at the desired speed when it's actually needed.

Orcaslicer also has a setting for Fan Lag time which is incredibly helpful.
This can be found inside the printer settings. -
