No functional test at manufacturer.
All the limit ports/terminals does not function. Z axis revert direction. Order replacement but still the same problems. I guess they didn’t do the functional test at manufacturer side.

Good CNC Router Controller
Good Router Controller Board for CNC 3018 Pro

Somewhat deceiving
I feel cheated. I purchased this item because it is a 3-axis controller. It can control both a laser "and" a spindle motor. Unfortunately, the software they provide is strictly for a 2-axis laser etching. Had I realized this, I may have searched a little more. Honestly, I have not even received the board yet so my comment is solely on the fact that the software provided is unusable for what I purchased this board for (milling).
