This CNC kit includs:

• 3 x Digital Stepper Drive 1.0-4.2A 20-50VDC for Nema 17, 23, 24 Stepper Motor
• 3 x Nema 23 Bipolar 3Nm (425oz.in) 4.2A 57x57x114mm 4 Wires Stepper Motor CNC
• 1 x 400W 36V 11A 115/230V Switching Power Supply

Driver Specification

• Input voltage 20-50VDC
• Anti-Resonance provides optimal torque and nulls mid-range instability
• Motor auto-identification and parameter auto-configuration when power on, offer optimal responses with different motors
• Multi-Stepping allows a low resolution step input to produce a higher microstep output, thus offers smoother motor movement
• 15 selectable microstep resolutions including 400, 800, 1600, 3200, 6400, 12800, 25600, 1000, 2000, 4000, 5000, 8000, 10000, 20000, 25000
• Soft-start with no “jump” when powered on
• 8 selectable peak current including 1.00A, 1.46A, 1.91A, 2.37A, 2.84A, 3.31A, 3.76A, 4.20A
• Pulse input frequency up to 200 KHz, TTL compatible and optically isolated input
• Automatic idle-current reduction
• Suitable for 2-phase and 4-phase motors
• Support PUL/DIR mode
• Over-voltage and over-current protections
