Introduction:

If you need a stepper motor driver for larger stepper motors that require high current, this driver can allow current draws up to 5.6 amps. Use this stepper motor driver for NEMA 34 and NEMA 43 stepper motors.

Description:

This is a new driver that we are using to drive the NEMA 34 and NEMA 43 Stepper motors. There is a maximum of 5.6 amps and a minimum of 1.4 amps that a motor can draw from this driver. Microstepping can be adjusted between 400 (1/2 microstepping) up to 25000 (1/125 microstepping)

[Motor Driver (24-70 volts DC, up to 5.6 amps, microstepping from 1/2 to 1/125)] What should be the wire connection

The wire connection to this driver will depend on What you are connecting to the driver.
- For the motor connection to the driver, use the motor's datasheet for the connection schema. If the motor has 8 wires, apply the bipolar parallel connection schema.
- For the power supply to the driver, use a DC power supply that does not exceed the rated voltage displayed on the front of the driver. 48VDC or 36VDC is recommended for this driver.
- For the digital connections from the Mach3 USB controller to the driver, the PUL- and DIR- should connect to the gnd terminal on the controller. The XD (the X-axis is used in the example) should be connected to DIR+ and XP should be connected to PUL+ For the Pokeys57CNC, the step pin connects to PUL-, the DIR pin connects to the DIR- and the 5v connects to the DIR+ and PUL+.

Step 21: Driver Caps, Resistor Networks and Mosfets
This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend purchasing a kit that is very stable from our wide range of machines available. The resistors are in, right? Ah, I know, you want to see the complete assembly before you dig in. Ok, on to this part of the assembly. Please don't ask me what Mosfets are, but the word sound cool! I can tell you that they stand for Metal Oxide Semiconductor Field Effect Transistor. I have personally read about fifty descriptions of this electronic animal and I still can't figure it out. It doesn't say much for a Berkeley grad! Well, I'm open to some plain English interpretations without the word "drain" in them. Are you still with me?

We will get to that a little later. For now, we will start on the assembly of the HobbyCNC 3 axis chopper unipolar stepper driver.
