Prusa I3 - Power supply stopped working

Hello, I have my prusa I3 a while now (from 11/11/2015) and suddenly my power supply stopped working. I gives a slight buzz when I set the power button on. (and the buzz keeps on going very silently.) Now my guess was it was fried or something similar so I bought the same supply to change it. But wh...

Re: RAMPS GT2560 with Pololu DRV8834

What do you mean by the steps.
Actually don't have a clue which one to use. I'm building a zortrax Robotarm and they just say use stepsticks. But not specific which ones.

RAMPS GT2560 with Pololu DRV8834

Hello, Can I attach the Pololu DRV8834 to the RAMPS GT2560 or won't that work the DRV8834 can handle 1.5 Amps, and my steppers are max 1.34 amps. I have this laying around and then I don't need to buy the A4988 or the DRV8825. Or can you tell me what I have to look for to see if it can work with the...

Re: GT2560 burnt heatbed socket

I measured it and I get for the Ohms 1.6 on the lowest stand of the multimeter? So is this ok or to much? Following question arise when I was feeling my fan for the circuit board should it blow on the circuitboard or take the heat away from it? Because I followed the build manual on my prusa I3 and ...

Re: GT2560 burnt heatbed socket

Well I've replaced the part and hooked everything back together. I'm at my 3th print now so far. And nothing happened. I guess the cable pulled the socket out of the plug and made it heat up due to not being connected. At least I hope so. Still I would like to know how to measure the bed to be sure ...

Re: GT2560 burnt heatbed socket

I've connected the new socket in place and connected the heating bed and when manually heating the bed it gave me a red light near the socket, so the mosfet is OK. Now the avoid it happening again, I still need to know what I have to measure exactly on the heating bed, because the thread doesn't mak...

Re: GT2560 burnt heatbed socket

So I've tried to measure the bed's Ohm's but I got 1 or 0. So I might be measuring it faulty. I looked at the thread u have shown me. I've set my multimeter on 200 ohms(the ringer) and tested both sides of the heatbed 'pins'. Though mine show different pins on the one in the thread U showed me. See ...

Re: GT2560 burnt heatbed socket

might be the poor quality of the plug, you can use a better plug to replace the current one. And how's the bed resistance? usually it is about 1.2-1.5ohms, if it's too low then I think the plug will not bear the high current. Where do I find better plugs? And how do I measure the bed's resistance? ...
