[Cleaning x/y axis rods?]

Rusty rods can be safely cleaned using aluminium foil and a wipe of wd40, remove the rods and rub with the foil, then wipe with wd40 on blue roll or kitchen towel. Repeat until smooth. Then machine oil and refit.

[ELECTRIC SHOCK FROM UM2EXTENDED+]

Hi , my printer housing is live/ static charged? not sure, but it gives me a weak, constant shock whenever I touch the edge of the dibond where the aluminium is exposed on the housing, also on the guide rails, and probably various other places but that's enough shocks for now, any idea how I can resolve it?

Thanks

Rich.
