3 AXIS (TB6560) CNC Driver Board 4 Stepper Motor Mill CNC Router

TB6560 3 Axis CNC/ Laser Machine Stepping Motor Controller. Support Mach3, KCam, and CAM in Linux. Specification:
* HUGE improvements from TA8435 based boards **
* Absolute maximum ratings: 40VDC @ 3.5 amps(peak)/phase motor output per axis *
* PC parallel port DB25 connector has being installed onboard
* Adjustable motor current at 100%, 75%, 50%, 20% of full current by on-board switch
* Built-in overheat protection circuit in TB6560
* This board is tested through KCAM, Mach 2/3, touborCNC CNC software.
*This board has been used in different design 3D engrave machines, millers, routers.
*Include manual control circuit to test all 3 axis step motors manually
* Step Current(r) extension board (Optional: See my other auctions): Step Current technology is used to decrease the current upto 1/2, when motors are in idle for all axis so as to protect expensive step motor and driver board for long time running.
* See TB6560 Datasheet by TOSHIBA. The full current is preset at 2.5A by resisters for this board (you can adjust it by changing them).
