In this video I’m testing a Nema 34 closed loop stepper motor.

Currently I'm working on rebuilding a large CNC machine. The machine’s axes weigh up to a couple hundred of kilo’s. This amount of mass needs a lot of power to accelerate and decelerate. To make sure I had enough power I went for the biggest motors I could find and that turned out to be Nema 34 closed loop stepper motors.
The Nema 34 closed loop stepper motor ,from this video, comes with a HBS86H stepper driver. The driver can take 18-70 volt alternating current or 24-100 volt direct current. I’m using a 48 volt direct current power supply for my setup. Closed loop stepper motors have an built in encoder that checks every movement the motor does. Is there a difference between the amount of steps the motor is ordered to do and the measurement from the encoder than the system corrects the mistake automatically. Closed loop stepper motors are for this reason very reliable even when pushed to their limits
The initial plan to control the Nema 34 closed loop stepper motor was with use of mach3. I ordered a Nvem mach3 motion card but I couldn't get it to work. In the end switched to an Arduino nano running GRBL 1.1 and Universal G code sender. It’s a much cheaper alternative and so far it's working great.
