Each of these gantries is driven by closed-loop servo motors and fancy ball screws, producing a total build volume of 77″x30″x20″. This open air version is printing in PLA.

The motor’s body was printed from ABS to withstand the heat during operation. [365 Robots] didn’t skimp on the testing either, creating a 3D printed closed-loop test stand with load cell and ...

The PD2-N can be operated in closed-loop mode. Through this field-oriented control with sine commutation, stepper motors run with real torque control, high precision and with low resonance.
