With Generation 4, all our line of 3D printers now come with the electronic expansion board named “Duex 5” (before, this was provided by default only with BIG-Meter and BIG-180X models).
By using Duex 5, a dedicated stepper motor driver is allocated for each Z and X-axis motor. As a result, Modix printers now offer a full set of automated calibration routines to all Generation 4 models, including automated bed tilt, bed leveling, gantry alignment, and Z offset calibration.
