Title
Here is a standalone stepping motor driver that is rated at 2.5 peak amps per phase. The driver will also accept a range of 8.2 to 45 volts and can be microstepped up to 1/32 (the step modes are: full, 1/2, 1/4, 1/8, 1/6 and 1/32). This is an exceptionally smooth 2.5 amp standalone stepping motor driver that can be microstepped up to a respectably high 1/32. The driver is also very easy to configure with only one trimmer to set the amount of current you will allow the motor to draw. The driver chip has all kinds of built-in protection including protection for heat and over current, so you can use this driver with piece of mind. The EN is an enable pin and will enable the chip at a low state (0 volts or GND). Left unconnected is the same as enabling the chip, so if you intend to keep the chip on when the system is powered, keep this terminal unconnected. The CW is direction where the motor will turn in one direction when high and the other direction when low. This terminal is generally connected to the breakout board on the terminal/pin you assigned in software for direction. In software, just change from active high to active low (or invert if using LinuxCNC) to reverse the directions. The CP is the step pulse terminal and this will step the motor (turn the motor single steps). The steps will be equal to the full step multiplied by the microsteps that you set the dip switch. There is a ground terminal next to the 12-24v terminal and that is a common ground for high voltage and signal voltage. If you are needing more detailed information, please refer to the driver IC DRV8825 datasheet.

Step 1
The LED and fault conditions: The driver's LED serves to indicate a fault condition. The driver chip has built in protection for overheating and over current. If the LED is on, most likely, the driver will stop until the condition is resolved. If you see the LED on, adjust the vref trimmer. First, connect a multimeter to the pads just next to the trimmer potentiometer and adjust until the voltage is lowered a bit. Alternatively, even though the PCB contains a vast amount of thermal vias and a relatively large ground plane connected to the belly of the driver, there still may be a need to cool the driver chip using a small heat sink. Do this only if you are not satisfied with the performance of the motor at the torque require.

  • Does "Additional Length" for the Lead Screw mean Additional Length in inches? So for the 4' x-axis I have to choose Additional Length=52?

    When you add a specific length to your cart, the additional length will be in inches. So you will need to add the total length which will be 98" in total! If this is for the scratch build kit (book CNC) the total length (98") of lead screw you will need for this machine is the three axes added together: X-axis: 52" Y-axis: 32" Z-axis: 14" You will have to specify the dimensions you require by sending a email (with your order details) or call to: customerservice@buildyourcnc.com or 281-815-7701
