Yes, the motor stops if the step wire is disconnected, however in this
condition the disconnected step wire picks up the occasional pulse
from the other axis' encoder and slowly moves the servo. This doesn't
happen when the step wire is reconnected, as it is tied either high or
low.
I'm using a deskcnc driver and a tek10 driver. The deskcnc one works
perfectly but the tek10 may have different requirements for the
step/direction inputs.It may be trying to oscillate backwards &
forwards with the quadrature inputs. Apart from this the tek10 works
perfectly when controlled from the computer. ( as it was designed to ).
