Description: This is SainSmart new CNC complete kit for engraving DIY. It comes with necessary and basic parts to make your own engraving machine. It is simple and easy to assemble the parts. Specification: Mach3 4-Axis USB CNC Controller Card 100KHz Support for 4-axis linkage, you can connect four stepper motor drives or servo drives; Maximum step-pulse frequency is 100KHz,which is suitable for the servo or stepping motor; Support automatic probe tool Support Emergency input Support for limit switch Support for connecting electronic handwheel Need use external 24V DC power supply to isolate USB and external port, and to make the system more stable. Have 0-10V output port, you can use mach3 software to control the spindle motor speed. 4 general-purpose inputs, you can connect the limit switch, estop switch, probe switch, back to zero and other device 4 general-purpose isolated relay drive output interface, can drive four relays for controlling the spindle starts, forward rotating and reverse rotating, pumps and other device; 1 status LED, indicate connection status on the board. TB6560 Stepper Motor Driver The use of new imported Japanese Toshiba TB6560 chip; The base used dense teeth radiator, cooling super, to ensure the stable operation of equipment; The input signal using a high-speed opto-isolation to ensure not losing steps, which the pulse direction signals with the same level of 6N137, dual high-speed optocoupler; A variety of semi-flow mode and the semi-flow current selection, the use of more flexible Decay mode is adjustable to ensure the motor running smooth; Compact Dimensions, cooling pad size: 75mm * 65mm, four mechanical installation positioning hole size is: 67mm * 58, mounting hole diameter is 4mm Set method detailed table on the board, easy to use; With anti-reverse circuit, even if not careful the power plug back and will not burn the chip, it's very safe to use.
