Davem - The machine is reasonably close to plug and play, unlike my first machine which was a pile of bits! My biggest worry is the two motors on the X axis losing step and the gantry alignment going. My plan then is to just wind it against the stops but if it happens (when) I'll take advice from the supplier first. So far though, there is no sign of any step loss.

The Tslot pieces can be attached to the bottom of the machine for deeper pieces, or for even deeper pieces left off altogether and the machine raised up (and presumably then solidly attached to ... well, something solid. I've a large slice from a chestnut tree which I plan to work. It should fit under the machine with the plates off and then I'll clamp the machine onto the 'table'.

I'd be interested to know more about your project ... do tell!
