Cura extruder esteps

[Mofroggy 0]

My extruder is only outputting 95.8mm of filament instead of 100mm that I run through it.

This is on an Ender3 printer.

How do I tell Cura to make up the difference?  Can I do it somehow in the "Start" gcode section in Cura.  Can anybody help me with the math?

I am not aware of being able to control this by software, someone else may. The normal method has been via your printer e-steps in the firmware. Easy to do but if you do want to change firmware settings you need to be sure on what you are doing and take it carefully. A bit like playing with the registry on a Windows computer!

As far as I know it should be possible to set e steps also via gcode, but I don't know which one. But I am sure there is a thread here in the forum. Try to search for Bondtech, I think in these threads there is somewhere the gcode command.
