Problem with heatbed

Yes,the only thing you should do is to ensure the two is to positive electrode.

I know which is positive and which is negative because it's written on the PSU as you can see:


Are you sure the order doesn't matter? Thanks again.

Yes,i'm sure.But you must ensure that the positive and negative orders are the corresponding.

Ok, Thanks!
What's the most practical way to check it, multimeter?

And can you please explain why you think it doesnt really matter? Im pretty sure it matyers because one is for the bed circuit and one for the extruder and control motors circuit...

My pleasure!No need to use a multimeter,it depends the wire's color.The red one is connected to the positive electrode,while the black one is connected to the negative electrode.

Hi!
Right before I finally move, I wanted to ask a few questions on RAMPS 1.4 so as soon as it arrives I'll be able to use it.

1. What's the recommended firmware for RAMPS 1.4 with your printer? I saw your firmware is based on Marlin, should I stick with it?
2. Does the Arduino get its power from the RAMPS 1.4 shield, or should I power it separately?
3. What happens when RAMPS 1.4 fuse burns?
4. Will it work with your dual extruder? https://farm8.staticflickr.com/7573/156 ... 5008_o.png
5. Here's what I'm looking to buy: http://www.ebay.com/itm/262155751015. The seller allowed me to buy it without the LCD and the cables (which I already have) for $27, and I wanna make sure - according to the pics, this is exactly and just what I need?

Thanks you so much! Hope to purchase it as soon as possible and make my printer work again.

Moreover, I wanted to ask a few questions on the printer itself which are not related to the controller:

1. How can I know what is the nozzle size?
2. I saw your newer pro C printers comes with an aluminum extruder holder and not a printed plastic. Can I upgrade it to this holder too? If yes, where can I buy it?

Thanks again.

Hi,there
1.Here is the downloading link:http://www.geeetech.com/forum/viewtopic ... 20&t=17046 you can find corresponding firmware you need.
2.You just need a USB cable to connect the RAMPS to your computer,the Arduino gets its power.
3.If the fuse burns only,you can change another one.
4.Theoretically，it can work.
5.I think that's enough.

1.You can find the size info in your order information,or you can ask our sales for help.
2.Yes,you can upgrade it.Here is the purchase link:
