How do I change my c
urrent setting on the
stepper motor drivers
?
There are 2 styl
es of stepper drivers that we hav
e for the E3. Both styles
work equally well, bu
t the
current needs to be
set with different values. The
yellow circles denote
the driver with the R20
0
resistors. The blue cir
cles are the R050 resis
tors. Note that these resistors ar
e in different locations.
