Fan speed during toolchange

danzaywer

Hello everyone,
I need help, is there a way to activate the tool fan 100% during the toolchange and bring it back to the value it had in the printing phase?
I'm on firmware 3.01 RC9
I could use objectmodels for something like

;in tfreeX.g
M28 0:/sys/fan.g
		M106 {object.fan.status}					
M29

and then

;in TpostX.g
m98 p "fan.g"

any suggestions?

It may be possible to do this without conditional g-code.

Prior to invoking your tool change macros, the system does the equivalent of a "G60 S2". Therefore, you can do a M106 Px R2 (where x is the tool fan) to restore. This would go at the very end of tpostx.g

Try this, I am not 100% sure it pushes the tool fan to the memory slot... but I seem to remember having done this with the print fan before.

Try as @Danal suggested.
