Current per stepper motor driver (NEMA 23 for CNC’s usually can take max 2.8A for max torque)Max. 2.3AMax 2.5AMax 4A but electronically limited to 2.8AMax 2.8A but software-wise set to 2.4A
Limit switches and Z probeNo pin for Z probe, but free pin on arduino. Pins for adding limit switches, but requires solderingConnectors for Z probe and limit switchesConnectors for Z probe and limit switchesConnectors for Z probe and limit switches
Attaching motorsTiny screw terminals – need extra wiring for Y axis as Y1 and Y2 motors wires share one terminalEach motor has it’s own connector on the controllerEach motor has it’s own connector on the controllerEach motor has it’s own connector on the controller
Attaching laserNo pin for laser, but free pin on arduino.

Physical button to set to laser mode

Connector for controlling laser

Connector for controlling spindle (requires relais) or laserYes, unused connectors are available, and can be configured in the software
GRBLYes 1.1Yes 1.1Yes 1.1
Compatible with UGS, Easel, etcYesYesYesNo
Cooling of the stepper drivers You can add heatsinks Heatsinks are recommendedHeatsink is optional as stepper drivers do not operate on full current (electronic reduction to 2.8A for motor protection)You can add heatsinks
Cooling of the housing You can add your own fan4cm 12V fan4cm 24V fanConnector for connecting 24V fan
