1. 4 Axis USBCNC breakout board

1) Products brief introduction

USBCNCV4.0 is a high performance motion controller which based on PC software USBCNC control, the system can complete the conversion from G code to connect stepper motor’s driver motion control signal without requiring any additional hardware and software. This control card is compatible with most stepper driver and servo driver,it is a perfect controller that instead of parallel Mach3 interface board.

This interface board is based on USBCNC MK1 and just use in our provide software and function, can not support update the firmware and use other versions of the software and function

3.Production feature

1. After the revision,V4 version using the red PCB board, PCB size is 135.3*82.5mm.;

2. The front of the narrow edge placed with USB communication interface and DB9 hand control interface for the convenience of customers drawn from the case panel directly;

3. The back-end of narrow edge is power input and output interface and 3 relay output interface; relay is strong interference source, relay away from the design of main control chip, it is conducive to the stability of the board;

4. One of the two wide sides is stepper motor and principal axiscontrol signal output;

5. The another side of two wide sides is the emergency stop, manual speed input, limiting input interface; one side for the input, another side output connection mode is simple and convenient;

6. 5V and 12V power module compact independence, security, stability;

7. External ensure the stability of the system work effectively with crystal active and main control chip shield;

8.outline dimension is 135.3*82.5mm, product positioning hole installment dimension is 127*75mm

9. pls note!  The software is USBCNC,not mach3, can't use Mach3 software.

This item is easy to operate for DIY hobby user,but it is control by USB port,so need more careful for the software install,and pls must be strict read the user manual and follow us.

2. FMD2740C stepper motor driver

FMD2740C Driver

Power supply voltage 18 to 50V DC

With the current of 1.4-5.6A

Subdivision precision 400,800,1600,3200,6400,12800,25600,1000,2000,4000,5000,8000,10000,20000 and 25000 optional

Drive any less than 5.6A current of 2-phase or 4-phase hybrid stepper motor;

Suitable for a variety of small and medium-sized automation equipment and instruments,for example: Small engraving machine, cnc router machine, etc.

Characteristics

• High-performance
• High-speed optocoupler signal isolation input
• Bipolar constant current chopping mode
• 20kHz chopping frequency
• Electrical input signal is TTL compatible
• Stationary current is automatically reduced by half
• Shape design is convenient for installation

FMD2740C driver is suitable for driving small and medium-sized phase current is less than 5.6A 2-phase or 4-phase hybrid stepping motor. Due to the adoption of the new bipolar constant current chopper drive technology, using the same motor can output more speed and power than other drivers. Segments stepper motor running accuracy improved, reduces vibrations and noise reduction.

Power supply

The supply voltage can work normally in between DC18V-50V, FMD2740C driver can use ordinary switch DC power supply, can also be used for transformer and the bridge rectifier and filter capacitor, capacitance desirable 2000U to 5000U. Note rectified voltage ripple crest does not exceed 50V.Recommended the user to use the 24V-36V DC supply , avoid the grid fluctuations over drive voltage operating range.

Electrical wiring

The FMD2740C driver can drive all current less than 5.6A 4-wire, 6-wire or 8-wire 2-phase / 4-phase motors.
