For now, I raised the two rear screws under the back of the glass bed a touch just while I'm experimenting. That raises the glass just enough to stop it sliding. I'm guessing that will affect my heat transfer, but as a temporary fix it'll do for now.

Actually, I just watched it more closely and realised that what is now happening is the glass bed is shifting! It's slipping forward every time the z axis moves. Is this caused by over extruding? Or should I just wedge some sort of shim under the glass bed to stop it slipping forwards?

use some stick glue along the edge or paint tape.

It sounds like they are being under driven now. That golden voltage is based on a machine that has no bind or abnormal resistance of any kind.

They were miles out from that before, but now I have them on the "correct" voltage as supplied by Solidoodle, they're jumping about all over the place. Now.... Problem is, I didn't make a note of the original settings....

How do I work out what to reset them to?

This "consumer printer" which was "ready to print right from the box" is doing my head in now.
