The bolt heads on the heated bed are dished, not flat, leaving them just slightly proud of the surface of the bed on my machine. Because I want to use a tempered glass surface for some output, the dish holds the glass about half a millimeter above the surface of the heated bed, making it unusable. I need either to grind them flat or to replace them. Does anyone know what the thread dimensions are?

Sorry. A Monoprice Maker Select V2. Having finally worked my way past their rubbish documentation, it’s clear that although the mechanicals are fine, the software’s a throwback to the stone age (fret not, so’m I) as the use of interpreted code is insane, imho. Plut a BT chip into the motherboard, for starters - mechanical connections are a recipe for a short life and a frustratingly merry one. And that then informs a whole raft of derivative follies, such as the need to replace the MOSFET interface. Fire Safety should have had this thing banned from Europe, and it’s still a moot point whether I simply use it to print something better and cannibalise it for the parts.

Already done getting thin toughened glass for the pad - you can’t get holes that small.
It rather sounds as if this is new territory, perhaps the answer’s to cut 1mm alu to size and sandwich the lot, when you put it that way! Any preferences for glues?
