Nativida – 01 Jul 2024
The motor performs as expected. It is used with a stepper motor driver and is easy to set up. Once we have placed an object to be cut and set the appropriate parameters, the result is very precise.
Kateryna – 02 Sep 2023
The motor looks to be solidly built. It runs quietly and has a lot of torque.
