Which is better for a CNC router?

The closed-loop kit is the safer choice for a router that can jam or take heavy cuts, because the encoder reports position loss instead of letting the axis drift. The open-loop kit works for lighter, well-tuned machines where 4.5 Nm is enough.

Is the closed-loop kit worth the extra $60?

Yes if a lost step ruins a part or crashes a tool. At $144.99 versus $85.00 as of November 4, 2026, you pay about 70% more for feedback, double the torque, and included cables.

Which motor is more powerful?

The closed-loop motor, at 9.0 Nm holding torque versus 4.5 Nm for the DM860TE kit. Note the DM860TE listing also shows 8.0 Nm in one field, so confirm the exact motor before ordering.

Do I need an encoder cable run?

Only with the closed-loop kit, which includes a 1.7 m encoder extension cable. The open-loop kit needs just step and direction wiring.

Which driver has more current headroom?

The CL86T in the closed-loop kit, at 0 to 8.0 A versus 2.4 to 7.2 A peak for the DM860TE. Both accept roughly 80 VAC input.

Can I run either from 48 VDC?

Yes. Both drivers accept DC input in that range: 24 to 110 VDC for the CL86T and 30 to 100 VDC for the DM860TE.
