Hi Traumflug,
I have the setup the same as for Prusai3 3D Printer.
I just want to know the purpose of the "Connector2" as the PSU will be connected to Connector1 & Heatbed will be connected to 'Heater".
Will it be fine if I let the Connector2 empty without connecting anything to it?
I am from Mechanical Engg background & has very little knowledge about electronics thatswhy I asked yo

Hello,
I have assembled my reprap 3d printer with ATTMEGA2560, RAMPS1.4, LCD & click encoder.
I have also modified the configuration.h & pins.h files for these hardware changes but lcd does not show any text.
Had any one added a lcd + click encoder to his 3d printer? If YES can you let me know the changes in firmware files.
I am attaching ine for ref.
Regards,
Prashant.

@ Traumflug,
I have assembled a seven switch 1.2.
Con1 is PSU +12v,
Con2 is.....? I don't understand what /where to connect this?
Heater is heatbed connector. But both pins of Heater connector shows 12v & 11v resp. Please clarify.
Please correct me if I am wrong.
If you can show me some images with all connections on ramps1.4 that would be very helpful

Hi Zachisparanoid,
I too got the same issue of melting the connector, but I used a large heatbed(10" x 10") without any relay.
Did you used the same large heatbed? If yes, do you use any relay circuit to draw more current out of PSU?
I tried connecting the #1 on J1 to PSU(ATX 450W) +12v pin on 20 pin connector as shown in image
I am using 6 pin relay.
But I was not successful to heat up the

Hi Dave3d, Airculd,
I made the relay circuit as per the image shown in -
I hear the click sound when I turn ON the heatbed in Pronterface, But the heatbed is not getting heated.
Any suggestions please.....

The motor works when connected to X, Y axis.... also it does when connected to E0/E1 but response is delayed....
It rotates with some time lapse....

Hello Dave3d,
Thanks for the info...
Mine relay is 6 Pin, DT90-1C-12VDC, (2 terminal for C, 2 for coil & 1 each for NO, NC)
NO : 30A 250VAC,
NC : 20A 250VAC
It didn't specified much details but similar to

@ dave3d, can you tell me how & where did you fitted the solid state relay, preferably a ckt diagram??
I have one lying idle at this moment, but I don't know how to use it. (12 Volt PCB Mount Relay - 30 Amp)
That would be very kind of you...

Hi,
I am using following in my 3D printer.
Arduino MEGA2560, RAMPS 1.4, ATX PSU, Marlin firmware, 300x300 heatbed.
Yesterday when I started the printer, I felt something burnt & that was the PSU connector which is connected to RAMPS.
What could be the reason for this?
Anybody had such issue??
I am using large heatbed without any relay. Is any relay necessary to fetch correct Amperes for l

I tried switching themotors.... it works fine. Motor is not at fault.
I even tried switching another pololu driver, still it does not work.
Any changes to be made in pins.h file for ATMEGA2560, marlin firmware?
