A bigger delta means you will at least triple the mass of the arms. This will require stronger steppers and probably will result in currents higher than your standard arduino printer electronics drivers can handle. I would also be leary of any material for delta arms at that length. Almost anything other than chromed linear rods will start flexing.

Oh, another thing: Heated bed. Your best bet is to use AC voltage heating bars and drive them with an SSR. You will not be able to find a DC heater big enough (unless you power the heater from a separate PSU).

Maybe they meant to put them in series and feed 110V~ (US-) mains to them? Has anyone done that before? ( and survived ? )Quote

heat bed.. yeah the other hackers said "we just chain up 9 mk2 beds"
i laughed and asked them how much current that would be
they thought at it for 1 min and came up with a approx 80A number and i told them to say 15A * 9 and asked where they would get a 12V psu rated that much at an fair price
before they could answer i added the bonus Q: why not use a 230V silicone heater and a SSR with zero point detection build in..... they humble accepted defeat :-D
But yes i i'm more and more convinced about a H bot... delta could be done... but the arms yes... it will be problematic to say it mild
let's see, we only meet weekly so it will not be until the end of week i know what they decide on
