So what do the values imply in terms of the stepper motors that can be run by these controllers? The downside is that torque delivered by the stepper motor decreases at higher microstepping values. The upside of higher microstepping in a CNC is that the motion will be smoother with less noise.

The stepper driver in the BlackBox can do up to 32 microsteps per full step.

Similar to xPRO v5, there are four stepper drivers in the BlackBox as well. Openbuilds does not specify the exact stepper driver used in their controller, but it can deliver a peak current of 4.0A. This stepper driver can do micro-stepping of up to 256 microsteps per full step. XPRO v5 uses four Trinamic TMC5160 stepper drivers that can deliver a peak current of 6.0A. XPRO v5 also supports push notifications, which means you can configure it to send you a text/mail when a job is completed on your CNC. That's less cable to manage and freedom from the wire length. This means with the xPRO v5 you can operate your CNC using your computer or phone via WiFi.Īlthough you have controllers like the Duet3D which support WiFi and Bluetooth, they are not based on GRBL (or its variants).

One major advantage to using the ESP32 microcontroller is the built-in WiFi and Bluetooth support. While an 8-bit microcontroller is good for most CNC applications, a 32-bit microcontroller offers much more processing power and memory. Without going into the details of the circuitry, I'll talk about the practical implications this has on each controller. It runs a firmware called the GRBL_ESP32, which is an open-source port of the GRBL for the 32-bit ESP32 microcontroller. On the other hand, the xPRO v5 uses a newer 32-bit microcontroller called the ESP32 manufactured by Espressif Systems. This also means Blackbox runs on GRBL 1.1 firmware and gets all the updates that happen with GRBL. The microcontroller or what is called "the brains" of a CNC controller determines how much space you have to tinker around with your CNC controller.īlackbox uses the ATMega328p 8 bit microcontroller, which is used in the most common Arduino boards such as the Arduino Uno and Arduino nano.īy using only the brain of the Arduino, the ATMega328p, Openbuilds has managed to shrink the size of the BlackBox controller while remaining within the Arduino development platform. They both have in-built heat sinks and fans to cool the stepper drivers during heavy loads. Openbuilds BlackBox Controllerīoth the controllers perform very well provided they are operated with the recommended settings. It also has a cooling fan that's open from the top side and has ports on three sides for connections.īlackBox uses a muscle and brains boards stacked configuration with the muscle board providing the electrical power and the brains board providing the processing power. Spark Concepts xPRO V5īlackBox is thinner in height but is larger in terms of length and width compared to xPRO v5. The cooling fan is visible from the top and has ports/receptacles on three sides. The xPRO v5 has a neatly enclosed ABS casing with integrated cooling. XPRO v5 is thick but small in terms of length and width compared to the BlackBox.
