Talk:PCB Heatbed

Hi,

More dimension data would indeed be most welcome! I need to prepare a support for one of these (not yet received) What is the exact distance between the holes? I have read 21 cm, but found no "official" confirmation. Thank you for any hints,

Answering my own question: checked on the PCB eagle file posted to Thingiverse, the holes are spaced 209 mm

I was not sure if to add the MK2 board to this page or start a new Wiki page for the board. in the end I redirected PCB_Heatbed_MK2 to this one and added the MK2 stuff here. They are minor changes but add up to a board that looks better upside down and is easier to mount connections, LEDs and a thermocouple to.

Slight mistake, Skyfanatic...Prusa made a series of heatbeds before arriving at MK1. And MK2 happens to be one of those earlier designs (baffling, I know). Might want to rename your design.

Threedonuts, my understanding was that those were just 'heatbeds' and specifically that MK2 uses a floor tile and nicrome wire. This is Prusa's PCB Heatbed MK1, improvements I have made seem to fall logically into PCB Heatbed MK2.

Hm, as long as you were aware of the earlier MK2. I was just surprised to see this name after following Prusa's work. Even though it's a floor tile and not a PCB, Prusa's Heatbed MK2 serves the same purpose as his PCB Heatbed MK1. In response to your above discussion, I think it's correct to use this Wiki page for. As you say, your board is a minor layout alteration, not a new development. --Threedonuts 16:26, 20 September 2011 (UTC)

Yeah I looked into the various options, nicrome wire, resistors etc and liked the PCB idea the best, now we just need a form of permanent, spray on 'kapton' for the glass! Skyfanatic 20.09.2011
