Easy to Build CNC Mill Stepper Motor and Driver Circuits 6 Steps with PicturesDont be nervus. Its just a little electricity. First off it would be good to load up the KCAM or what ever you plan on using in your computor. Then when you feel comfortable that all the parts are in the right place plug the parallel port connector into the driver boardas shown below and put a low wattage build in the socket for the motor. In this case Im using middle, the Y axis driver. PoA6JIFMcf0/hqdefault.jpg' alt='Bipolar Stepper Motor Driver Uln2003' title='Bipolar Stepper Motor Driver Uln2003' />UPDATE I finally have a follow up video on how to drive this motor with an Arduino Check it out at http The sample code from my. At first I attempted to use for the motor voltage the same 5V supplied by Arduino but because of the floating middle point the max voltage across each winding was. Phase A Phase A Stepper Motor Phase B Phase B LowSide or HighSide SwitchDriver LowSide or HighSide SwitchDriver R PHASE L PHASE V CC V CC Phase A Phase A. RR4fsh_drQ/UBgq59utj7I/AAAAAAAAALI/VBOzZ37XLCY/s1600/bipolar_stepper.gif' alt='Bipolar Stepper Motor Driver Uln2003' title='Bipolar Stepper Motor Driver Uln2003' />For power I like to use one if these universal power adapters with selectable voltage output. Theyre cheap and they dont put out a lot of current so if something goes wrong its less likely to damage your circuit. Set the voltage low and see if you have some vlotage on the power pins1. CD4. 51. 6 and the CD4. If you dont have a volt meter just take an LED and tie a 1. KBRN,BLK,ORN resistor to the positivethe long leg and wire to ground tied to the negativethe short leg. Now you can use this as a probe to see where you have voltage. Micro-Cap 11 Crack here. At Risk Youth Programs In Northern Virginia'>At Risk Youth Programs In Northern Virginia. It will be very dim but we dont want to draw too much current away from the circuit. Now go into the computer program and find the Setup Table. Bipolar_stepper_driver.png' alt='Bipolar Stepper Motor Driver Uln2003' title='Bipolar Stepper Motor Driver Uln2003' />Set the steps per inch to 1. Then open the CNC control and set the single step for. Now each time you click the yellow arrows up and down for the Y axis the computor will output one pulse to the stepper motor driver circuit. Put your LED probe on pin 1. Bipolar Stepper Motor Driver Uln2003' title='Bipolar Stepper Motor Driver Uln2003' />CD4. This is the up down input. When you click the up arrow the input will be lowLED off and when you click the down arrow the input will be highLED on. Pin 1. 5 is the step input you will see a very short blink each time you click a n up or down arrow on this pin. Pin 6 is the Q1 output. It will change statehighlow each time you click an arrow. And Pin 1. 1 is the Q2 output. It will change state every other time you click an arrow. On the output side of things we should see some activity on the CD4. Putting your probe on any of the output pins 1,4,6,or 7. These outputs drive the FETs. You should see the output go high every 4th time you click the up or down arrow. If this all makes sense so far its time to get the motor running. The common wire or wires of the motor which are the center tap of the windings should be connected to the light bulb. The other four wires should go to the four FETs on the circuit. If you are really lucky you will get the combination just right in the first couple of trys. Other wise just keep switching the wires arround until the motor steps in the same direction each time you click the arrows. Watch the video in the next step. It may give you a better idea what to do. Electronics Projects for Engineering Students.
