Introduction
The CNC Printer Port Interface 1.1 is used to connect Stepper Motor driver cards and Modules to your
PC. The card is equipped with opto couplers and IC’s to ensure the PC doesn’t get damaged in case a
mistake has made. If a mistake has made, only the opto couplers or ic’s of the Printer Port Interface
1.1 will be damaged. These components are low cost and easily replaced.
The features:
1. Connect the 8 Printer Port Databus outputs to Stepper Motor STEP/DIR Control inputs
using TTL buffering
2. Connect the 5 Printer Port Control input lines to the End Switches and Emergency
Stop Switch using optocouplers
3. Connect the 4 Printer Port Control line outputs to Relais outputs using 12 (or 24) volt relais
driver
The card is compatible with most CNC controller software like:
-
Mach2
Mach3
PC-NC
Turbo CNC
CNCprofi
DINCNC
EMC Kcam
The Card supports 4 stepper motor (or Step/Dir servos) outputs, with 4 end switch inputs, one
Emergency Stop input and 4 12 volt relais outputs. You can connect to your printerport using the
SubD Female connector, or a ribbon connector. The card has LEDS for all 3 power voltages, and
LED outputs for the Spindle ON/OFF output and the 4 End Switch inputs. The Relais outputs
current can be doubled for use of extra big relays or electromagnets. For people who have
homebuilt stepper drivercards or other printerport applications a 10 pin header with all STEP/DIR
outputs and VCC/GND is provided (printerport databus output).

4 Way’s to connect a switch:
Note:
For save operation it is recommended that the inputs
get a constant signal. In event of an broken cable, the
system will see a loss of signal and will react to it.
1. One switch. Connected as a
normaly closed circuit.
Use the normaly close (NC) contacts when the switch
are triggert at the switching point.
Use the normaly open (NO) contacts when the switch
is triggered constantly and will be released at the
switching point.
2. Two switches. Connected as a
normaly closed circuit.
3. One switch. Connected as a
normaly open circuit.
4. Two switches. Connected as a
normaly open circuit.

Some SSR relays need a pull-up resistant to function.
If you use a relay of your own, check the manual before
you connect it!
When you use a standard relay, make sure that you use a
anti parallel diode to avoide damage.
