Freeshipping LY CNC router 3040 Z VFD with 1.5KW spindle, 3 axis cnc engraving machine for metal wooden stone-in Wood Router from Industry & Business on Aliexpress.com | Alibaba Group
with 3 buttons at control box front side.( power, e-stop, speed ctrl), ivory colored box,
i opened box, and all i can see is boards. no LCD or something like that
