I'm interested in adding a heated bed to my Prusa Mendel but I do not own a soldering iron (I live at college, too many smoke alarms). I've seen a few heated beds on ebay for sale but they aren't quite clear about how exactly you attach it to the printer. (like this one here: [www.ebay.com])
Would anyone be able to give me some advice about how these attach on or whether you've found a better one that just plugs straight in?
Haha that's good to hear. Yes they do, but I'm studying Biomedicine rather than Engineering so I can't get access to it. I could, however, ask one of my engineering friends to do the soldering for me. Have you attached a heated bed before? Do you know much about what's involved if I got the one on the ebay link?
The helios print bed from www.panucatt.com has screw-on power connections. The thermistor requires a bit of light soldering, but there is no need for the heavier soldering needed for the power connections. These soldered connections are - in my opinion - the biggest problem area with regard to installing these beds.
On ebay you can post questions to the seller to clarify if it needs soldering. On the heated beds that I got the thermistor wires were already soldered. I just had to cement the sensor into the hole and use kapton tape to tape it to the bottom of the board. You will want either zip ties or split wire loom to bundle the wires together. If you plan on using non PLA filament you may wan to add insulation to the bottom of the board.
