STEPPERONLINE Nema 34 Stepper Kit vs StepperOnline YS Closed Loop Stepper CNC Kit

The StepperOnline YS Series closed-loop kit is the better buy for most CNC builders. It adds encoder feedback, so the driver corrects for lost steps and stalls instead of silently ruining a cut, and its 6.5Nm motor out-torques the 4.5Nm open-loop motor in the STEPPERONLINE kit. The STEPPERONLINE kit is simpler and cheaper to run open-loop, but it has no feedback and no stall protection. Owners of closed-loop Nema 34 kits consistently report fewer skipped steps under load; open-loop kits are fine for light, well-tuned hobby routers.

• Choose the STEPPERONLINE DM860TE kit if you run a light hobby router or plasma table with a known, forgiving load and want a plain open-loop setup with no encoder tuning.
• Choose the StepperOnline YS Series kit if you want closed-loop feedback, more torque and stall protection on a machine where a skipped step ruins a part.
