Questions on using a moving gantry style mini-mill...

Vaguely possible but why only slip 0.2mm and not just keep going as usual?

The second and third tools were spot-on which indicates the initial height sense was good, i think.

If it did slip the torque from cutting and centrifual forces or heat generated in the tool could have locked it tight again.

One plus for leaving my cast iron bed for later use if I feck up a bit of MDF or even some Aluminium extrusion I won't be to upset but I don't want to replace a 1000x700x50mm cast plate that has been ground

[Davek0974]

Yeah i also have a cast iron bed but its only ever for use as a sub-bed, the part that has been mauled is only 15mm Eco-cast plate so i'm not bothered too much, will likely end up taking a skim off it anyway.

Only reason I didn't use mine is I don't like shredded wheat enough to eat three, or the fact that after having it ground flat advised to leave it on steel base, either part I could find a couple of mates and man handle up a flight of stairs into my flat but together they're almost 0.4 of a ton and can wait until I move again and have my workshop at ground level.
