Chapter 1 Overview

1.1Simply Introduction

DDMMV2.1, which name is short for “Digital Dream Multiple input Mach3 card

Version 2.1”is a CNC system based mach3. This card is designed by our Studio You do not

need to add other Hardware，and you can complete the signal conversion from the G-code to

the movement of the stepper motor drive control. You should use both parallel port and usb port at

the same time.This card is compatible with most stepper drives and servo drives. And it is perfect

weapon to replace mach3 parallel interface board.

1.4 Notes and Cautions

� Prohibits the rain, boards for high-performance precision equipment, rain can

cause short-circuit

� CAUTION WARNING, various wiring in strict accordance with installation

Description document specification.

� High risk, boards need to stay away from high-pressure.

� A)USB PORT，This interface is connected to the computer through a USB line.You can

use the software mach3 to control this board, Note that you should use a USB2.0 cable

with shielding and ferrite core,and cable length should be not more than 2 meters.This

USB port not only provides power to the board, but also manages output&input port、

hand control box interface and spindle control port.

� B)LPT port.LPT port should be connected to parallel port of PC.LPT port only manages

6axis stepper motor driver.

� C)Input port to parallel port. There are input10\11\12\13 of parallel port. Wiring

methods see as Figure 2-2,you can link a Micro Switch to GND and INLX(X can be 10

11 12 13). Internal circuit of INPUT10\11\12\13 see as Figure2-3.

Figure 2-2 Input port to parallel port

Figure4-5. Motor operating parameter settings dialog

The parameters are defined as follows: Steps per：Pulse equivalent ,it is number of pulses required with axial movement 1mm, This can be calculated by lead screw pitch and motor drive segment. Such as pitch 2.5mm,2-phase motor 8 segments, Calculation method is 8*200/2.5=640。 Velocity：The speed is the axial velocity, Units is mm/s，Recommended settings 1500. Acceleration：Units is mm/s2，Recommended settings 200. Step Pulse：Minimum pulse width,Recommended settings 2. Dir Pulse：Minimum width direction, Recommended settings 2. Attention:The parameters for each axis is not necessarily the same，To select the axis,

and then set parameters. You should click “SAVE AXIS SETTINGS” After setting.
