Pin 15 input vacant
Pin 18-25 signal mass (0V GND)
Port LPT2 is used analogously to clock/direction version and can
liberally be assigned on the in- and outputs.
Further technical information concerning controlling SMC cards can
be learned from documentation of the card. If the additional signals
or vacant inputs of LPT1 are to be used by the machine, they have to
be tapped directly on the cable.

Attention !
For safety reasons it is essential to use limit switches on all axes.
In order to avoid accidents by contact during operation it is
advisable to install a system for access control, e. g. a protective
housing or a savety fence. Please connect these safety appliances
with the controlling component and define the corresponding
inputs.
5.2. Determination of axis resolution
For calculating the required distances and speeds it is necessary to
tell WinPC-NC precisely the defintion of the axis resolution.
Two parameters
for avoiding
calculation
inaccuracies
Please open the paramater dialog box parameter - machine and
determine the exact data of your mechanics and drives for each axis
by the first two paramaters.
The paramater axis resolution defines the number of steps or
increments per rotation for the corresponding motor. Please consider
the electronic settings relating to the macro/micro stepping operation
and a possibly integrated reduction ratio.
Motorsteps and
distance per
rotation
The required value is the number of motorsteps WinPC-NC has to
create in order to carry out exactly one rotation round the spindle or
the shaft.
The second paramater distance per rotation defines the distance
which is made exactly by the number of above mentionned
motorsteps. With spindles it is the spindle rise or with belts or gear
racks it is the graduaded circle size of the pinion.
