As im being quoted, I feel the need to re-post for clarity

I stated my first machine was made using drawer runners, printer steppers and mdf... I didnt point out how shockingly bad it was!!!

think how much "play" there is in drawer runners.... then imagine what that would do if you were engraving on something mounted to them

Have a guess how long you think it would take before the screws holding the mdf machine together work there way loose in the soft mdf material and the entire thing starts wobbling.

and mentioning the TB650 driver; was meant, in a bid to try and warn you against it...

read carefully what people have wrote here; they are all right. Although it is "possible" to make a machine using household items... it may not necessarily do what you want it to do.

dont buy any electronics before reading and asking here first.
