How to assign a value to a node? Or: Error: expected '='

[DavidG_68kg_PLA]

How can I reset my extrusion factor via a macro (prior to the print start)?

My macro looks as follows:

if move.extruders[0].factor != 1
	set move.extruders[0].factor = 1

i usually get the following error:

Error: expected '=' in line 2 of Reset Speed and extrusion factor.txt

I already experimented with braces and different order - but i didnt get it to work.

Thank you in advance!

@DavidG_68kg_PLA You cannot write to the object model directly using set, it only supports local or global variables. Use M221 D0 S100 or M221 D0 S{myFactor * 100} to set the extrusion factor.
