buying a cnc machine from China is very tempting because they're cheap, so I bought one. 40" by 24" 4 axis engraver through ebay which looked very nice in the picture.
it arrived to London with little damage but nothing drastic.
believe it or not, this machine was NOT made with a cnc machine!!!
very crude cut and shaped with a file aluminium parts and spindle mount. nevertheless, I said non of these would stop me using the machine.
electric wires very poorly insulated, some not insulated at all, passing through tiny holes in driver stainless inclosure without grommet or conduit. here I had to stop, made the holes bigger, and insultated the wires with conduit to prevent imminent electricution.
only 2 of the axis worked, out of 4, and spindle never worked. this is not the end of the world, every thing can be fixed.
z axis went haywire while testing and broke the coulpling, luckily it was cheap to fix. now it developed a nasty growling sound.
last but not least, the drivers inclosure almost cought fire today. but honestly, the smoke it made was probably worse than fire. NOW I HAD TO STOP.
I don't know what went wrong.
very poor instructions, only pictures on a cd to show how to set it up.
I think it was a total waste of money.
