Aurora ★★★★★ Oct 22, 2026

The 110v label matched my machine setup perfectly, so installation was straightforward once I matched the labeled pins. Spindle runs smooth and the clearance issue I was worried about never appeared, though the board is a little bulky to mount.

Ryan ★★★★★ Oct 21, 2026

The included manual made wiring into my older 3503 a breeze, and the board itself has a nice solid feel to it. I was worried about the clearance label, but everything was packed securely and works perfectly on first power-up.

The harness connections are clearly labeled, which made swapping out the old board on my 3503 CNC take less than ten minutes. Pairs perfectly with the spindle on my mill.
