Topic: Working on a new glass bed
Making it to clamp electro magnetically. Good or bad idea and why? Also it will have its own clamps that I can switch on and off bc obviously aluminum isn't magnetic.
Re: Working on a new glass bed
Interesting idea at least! I don't see any thing why it would be bad Idea. Are you planning electric magnets just for fun or are there some reason? It would be cool 
I see normal magnets would do the job as well, as long as you put someting to attach for them!
Re: Working on a new glass bed
Im planning on electro magnets for the reason you could flip a switch and easily remove the glass plate without knocking things out of adjustment. The best way to get prints off is to take the plate off, let it cool to room temp. then put it in the freezer. the prints literally pop off and you dont scratch or damage anything scrapping them off. I'll post more at the end of the week. I have an improved heated bed to prevent warping.

Re: Working on a new glass bed
Sounds like a go-er: solenoids and electromagnets use a fair bit of power run continuously, make sure you spec them for continuous duty and use big enough power supply / relays.
I suppose once you have a clamping method that can be switched on and off with a relay, you have a pretty good start on an automatic plate-changer...
My thoughts on arrangement attached (note I don't value the outside edges of my build plate much, but sketch may be a bit exaggerated in it's build-area-wastage) but I think you've got this!
SD3. Mk2b + glass, heated enclosure, GT2 belts, direct drive y shaft, linear bearings, bowden-feed E3D v5 w/ 0.9° stepper

That's pretty much my plan except the electromagnet will plug into an out let and have a switch
That way you don't have to solder a board or mess the currents up on it.

Re: Working on a new glass bed
using the bed heater pad support puzzle from thingaverse on aluminum bed?
Solidoodle 2 with Deluxe kit cover & glass bed with heater. and 2nd board SD2 used not 3rd and alum platform not installed yet still wood. also need cooling fan installed to board. use Repetier Host couple vers. Slic3r also have all free ware STL programs
Re: Working on a new glass bed
wow...nice plan you got there!
