There are two analog output terminals that can supply a 0 - 10 V signal to control an external accessory that you may use. You can connect the VFD to the controller via the breakout board and use the control software to control the speed and torque of the spindle. The controller board comes with an RS485 chip that you can use to communicate with VFD controllers. The breakout board has a PWM pin that you can use to connect to a laser module or control a low-powered spindle. Such spindles are usually used for engraving and PCB making. It has a 0-10 V output that you can use to run a simple DC spindle. The breakout board has a pin where you can connect an E-stop button for stopping the machine in case of emergencies. You can connect a Z-axis probe to the controller via the DB25 breakout board and automate zeroing the Z-axis. Typically, most similar controllers support three-axis limit switches but the Buildbotics controller has limit switch support for four axes. The breakout board has eight terminals to connect limit switches. This means it can tell the stepper motor to turn 2,50,000 times in a second, making it really fast.īuildbotics provides four 10 foot long cables to connect the motors that you can plug into the four motor ports at the back of the controller.

This allows your CNC to run smoother and retain its precision for longer.įurthermore, the controller is capable of sending 2,50,000 pulses per second. S-curve acceleration is a great feature that prevents jerks that occur when the motor starts and stops.

The drivers support 256 microstepping and S-curve acceleration. However, the controller comes with several protection features to prevent damages due to over current or temperature.

You’ll have to desolder the SMD driver chip and solder in a new one. This means if you burn one of the stepper drivers, it is quite difficult to repair. The drivers used are based on Texas Instrument’s DRV8711 stepper drivers and are embedded onto the main PCB. This means you can use most NEMA 17 and 23 stepper motors, some NEMA 34 stepper motors, and any other stepper within a 48V 6A rating. The controller can supply a maximum current of 6 A to each motor. The first version supported up to 36 V, but now there have improved the power supply to support a maximum of 48 V. With Buildbotics, you can drive up to four stepper motors that require a 24 - 48 V supply.
