Alright so basically the Edge 2 has 2 motors. It has one on the horn, meant to stimulate the balls and then one in the prostate massager that gets inserted. From what I understand funscript player only really utilizes one of them? But MFP recognizes both motors and you can assign a different axis to each one or the same axis, the main thing is you can get MFP to actually activate both motors.
So L0 is the standard stroke axis that any .funscript file will go to. There are two vibrate axises in this, v0 and v1. You can get both axises to respond to .funscript/L0 by either making v0/v1 read .funscript or by turning single-axis scripts into multi-axis. The other thing that this is good for is that if you have 2 or more scripts you can use each motor with a separate script.
Ex. If a script has a stroker script and a vibe script, you can assign one to each so its 2 different scripts. Or in the rare case where it has a vibe1 and vibe2 script you can have 2 separate vibe scripts.
As for step for step guides you’ll have to look up guides on here and fiddle around with it, I set this stuff up a long time ago and I dont remember how to do it without relearning all of it and at that point you might as well read it yourself.
