I have finally installed slim and got everything working. I don't quite understand how to use slim, it seems easy enough but maybe I'm just dense. I look at the examples and there is a lot lines that start with echo, what's that?
echo Motor settings
echo---> Base speed=5, ramp=24,dir=0
motor 0 enable 1
motor 0 dir 0
motor 0 steps 5
motor 0 ramp 24
I can figure out some of this but what is echo used for?
