Re: silicon rubber heater bed -120 Deg celsius in 1 minute

It is one of those universal supplies, that you put different plugs on the end of the cable, and select the correct voltage for your laptop. So it is more of an adaptor than a power supply. It has no other voltage feeds (apart from an optional USB power port).

Also had the realisation, that this setup allows to run both the stock heater, and this new heater at the same time if I crazily desire.

Re: silicon rubber heater bed -120 Deg celsius in 1 minute

I see smile well then that ought to work pretty good, should heat up quicker with both being powered smile

I will probably be doing some sort of heated bed mod also, just haven't decided what as of yet... plus I have a bunch of other projects going on all of the time too.(spend way too much on RC aircraft wink )

Question for Lawsy. The jumpers mentioned in your post. Did you add the jumpers between the adjacent +12V and -V pads for the bed connector? Want to be sure before doing it.

Just got some glass, and at the moment I'm still finalising my setup by designing and printing mirror holding clips, but some of my pictures for my upcoming guide are ready:

Re: silicon rubber heater bed -120 Deg celsius in 1 minute

lawsy,
Can you list the part numbers you got for the better connectors? I want to add this mod and like how you have it done.
Thanks

Let me know if you have any other questions.

So you switched from the original screw-terminal of the original power supply to your parts?
And you only changed the original power supply to the GS220A12?

Re: silicon rubber heater bed -120 Deg celsius in 1 minute

Yes and yes.

I have since upgraded to RAMPS 1.4 and an even more powerful supply.

I'm thinking about using the original parts for other projects.

Re: silicon rubber heater bed -120 Deg celsius in 1 minute

I haven't even printed anything yet and I'm already thinking about upgrading to the Azteeg x3... I'd like to add some LEDs and upgrade the bed..  there's not much you can do with the stock board, even the new one

That's not completely true. There are spare pins that you can use and if you upgrade the Chip from an ATmega644P to a ATmega1280 you can use a display and a bunch of other things. The sanguinololu isn't completely useless and neither is the printrboard. I suggest running your stock board for a while first then figuring out why you want to upgrade. You might find that you are happy with what you have.

Glass bed with QU-BD heat pad upgrade, threadless ballscrew w/ 8mm smooth rod, spectra line belt replacement, lawsy MK5 extruder, Lawsy replacement carriage, E3D hotend, Ramps 1.4 w/ reprap discount controller, DRV8825 drivers, 12v 30A PS, Acrylic case, Overkill Y-idlers, Filament alarm, Extruder fan + more.
