DDUMV5 6 Axis USB Mach3 Board 2000KHz CNC Machine Stepper Controls Drives Card DDUM6V5.0 is designed by our Studio, it is a CNC system based mach3.Its version is 5.0 now.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. This card is compatible with most stepper drives and servo drives. And it is perfect weapon to replace mach3 parallel interface board. DDUM6V5.0 is 6 axes mach3CNC card. Each axis port can general 2000Khz plus for stepper motor driver or servo motor driver. 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. B)6-axis stepper motor control signal output,axes are defined as X\Y\Z\A\B\C from left to right. Each axis is defined as COM+\CP-\DIR-. They are positive common, negative pulse, negative direction. This card is common positive connection, so CK+ and DIR+ of Stepper driver should be connected to COM+. This board does not support the common negative connection. See as Figure2-2. This card doesnt have EN signal, Most drives on sale should not connected to the EN signal. About 7-10 business days to your address We will sent the manual in English to your email box.
