flow rate
Hey guys, may I please ask I have a problem with setting the flow rate in the Prusa slicer (extrusion multiplier). Whenever I set it to, let's say, 1.05, the G-code does not apply this command, and I constantly have to change it manually in the printer, and I don't want that. I am using the generic PLA, and it is 1, but the G-code on the printer presents 95%. what can I do?
Best Answer by JoanTabb:
Flow rate and extrusion multiplier are different ways of influencing the quantity of filament deposited by your 3D Printer
Extrusion multiplier raises or lowers the ammount of filament calculated for each move within the slicer when the G Code is created.
Flow rate tells the printer to modify the ammount of filament that the G Code advises for every move and modify that ammount by the flow rate value.
Flow rate can be added in the slicer when the G Code is created, or it can be changed during printing from the LCD Controls (or both)
you need to be aware that Prusa often include a conditional Flow rate value within the 'Custom Gcode >Start Gcode' section, within Prusa slicer
see the line hilighted above.
IF you put your flow rate command before that line in the custom Gcode, then that line will over ride your command.
I suggest that if you want to modify the amount of filament used, at slicing time, you use the 'extrusion multiplier' setting
and if you want to modify the amount of filament used, during a print session, you use the LCD Controls

RE: flow rate
Oh yes, I just checked it now, and it worked. This is so helpful thank you so much needed this.
