Yep thats one of THE most important ingredient Geoff.?? . . . It keeps the fire going.!

Seriously now.!! An amusing now but scary then thing happened with that MDF.? It was used for the bed initially and the first Job was the obligatory Mach3 Road runner drawn with a pencil held in 1" square off-cut of Ali with hole drilled in end and pencil jammed in. It performed flawlessly and after many other doodles I was satisfied and set about some fine tuning and checking of the motors with dial indicator.
So while using the MDI (manual data input) I told the Z axis to go down 10mm.!! . . So I thought.?? Nope some how an extra zero slipped in and off it went on it's way 100mm down.!!! . . . . In the blink of an eye it punched a perfect 1" Sq thru 2 x 18mm mdf sheets and the Z axis didn't flinch just did has it was told. .
