Nema34 Closed Loop Stepper Kit 4.5N.m vs StepperOnline YS Closed Loop Stepper CNC Kit

The StepperOnline YS Series kit is the superior choice for heavy-duty CNC applications requiring high torque and long-term durability. While the Nema34 CLE34 kit offers a compact solution for lighter loads, the StepperOnline version provides significantly higher holding torque and a more versatile driver. Owners prefer the YS Series for its industrial-grade cabling and the inclusion of a dedicated debugging cable for fine-tuning.

  • Choose the CLE34 kit if you are running a lighter machine that requires less than 4.5N.m of torque and you prefer a driver with a lower DC voltage ceiling.
  • Choose the StepperOnline YS Series if you need maximum holding torque for heavy cutting and require high-flex cabling for dynamic machine movement.

Questions and answers

Which kit is better for a heavy CNC router?
The StepperOnline YS Series is better because its 6.5N.m torque provides 44% more holding power than the CLE34, which is critical for moving heavy gantries without losing steps.
Do these motors require an external encoder?
No, both are closed-loop systems with integrated encoders that provide feedback to the driver to prevent stalling and position loss.
Can I use these with a 24V power supply?
The CLE34 kit supports 24V DC, but the StepperOnline YS Series requires a minimum of 30V DC to operate correctly.
What is the benefit of the RS232 cable in the StepperOnline kit?
It allows you to connect the driver to a PC to tune PID parameters, monitor performance, and adjust current settings beyond the physical DIP switches.
