5 Home built parallel breakout board.įig. 4 TB6600 stepper motor controller basic electrical connections.įig. Setting switches S4, S5, and S6 to 0.5 amp or 1 amp assures say a 12-volt power (with the correct current rating) can drive the 5-volt motor.įig. The TB6600 also has built in current limiting which makes motor voltage easier to deal with.įor example I have 5-volt 1-amp stepper motor. 3 TB6600 stepper motor controller current limit switches. In the case of the 1.8 degree per step motor, 800 steps are required for 360 degrees.įig. Using 4 as an example, dividing 7.5 degrees by 4 = 1.875 degrees per step or 196 steps for 360 degrees. Setting the switches divides the step angel, not the number of steps. A 1.8 degree per step motor requires 200 steps for 360 degrees. S1, S2, and S3 are step multipliers for 360 degrees.įor example my motor in the video was 7.5 degrees per step or 48 steps for 360 degrees. Note the three control connections for micro-stepping. Micro-Stepping Setup, Common Ground Connections 2 TB6600 stepper motor controller micro-stepping switches. These will be explained next three slides.įig. Three of the setup switches select the current limit. It has three control connections (enable, count, direction), four connections for a bipolar stepper motor, and six setup micro switches.

Here I will use this with a PC parallel or printer port. I did two videos and a webpage on using the TB6600 with an Arduino microcontroller. It is single axis and operates bipolar stepper motors from 9-volts to about 40-volts at about 4 amps. The TB6600 is a cheap stepper motor controller available in Ebay for about $10.
