One more thing I’d like to add. I use a Mac computer, and if you use the Softfever version of Bambu Studio and follow the instructions for flow calibration using the built-in calibration steps, you can use the following AppleScript to make it simple to perform the instructed calculations. If you’re not used to AppleScript on the Mac, just launch the Script Editor.app, paste the following code into an empty document window, press run and answer the prompts:
set FlowRatio_Old to text returned of (display dialog "Please enter current (old) flow rate:" default answer "0.98") as real
set ModifierValue to text returned of (display dialog "Please enter the Modifier value that you selected when you ran the test:" default answer "5") as real
set adjusted_FlowRatio to (FlowRatio_Old * (100 + ModifierValue) / 100)
display dialog "Your new Flow Ratio value:" & space & (adjusted_FlowRatio as text)
