Aurora Z605 3D Printer

Hello,

I recently purchased an Aurora Z605 Printer. I completed the physical build and then wanted to upload firmware to the Melzi board that came with it. I couldn't find any guidance for the firmware configuration from the company so I was kind of in the dark. Initially the Marlin files I found online wouldn't even compile but I found the Repetier Firmware does compile but when I try to upload it to the correct serial port it returns the avrdude timeout error. When I open repetier host and click connect it says that it is connected but the arduino IDE can't seem to connect. What should I do?

What about the ftdi drivers (though I doubt this would be your problem), you could try here [reprap.org]. Usually 3d printer kits comes with preloaded firmware. Often you don't have to worry about setting up those firmwares unless you're going experimental

I just realized that the controller does come preloaded with firmware. I think that the FTDI drivers might be the problem. I don't have the disc that has them on it and am trying to run the printer off an Ubuntu desktop. Where do I find the drivers and how to I install them to connect the printer to Repetier-Host?

Sorry, I run on windows, here is some guide to get you started [learn.sparkfun.com]

Terrible printer, can't get it to work. It has worked with repetier and then it stopped working. This thing is driving me mad.

Gday
Fairly new to 3d printer technology and hope I am sending this to the correct place.

I have an issue with the heat bed on my Aurora Z605.

I built it from a kit and after a few initial hiccups it was working well for 12 months. Then, the heat bed would not heat up.
I have changed the thermistor, new melzi 2.0 board and now the heatbed to a MK2B. Yet still no heat...
Feel like I have read every post about this issue yet cannot find a fix.
The resistance changes when i heat the thermistor but I do not get an output voltage on melzi heatbed connectors

Using repetier Host and tried Repetier and Marlin firmware - a copy of current Repetier configuration.h Configuration_h.txt.txt
and pins.h pins.h.txt attached

Any advise appreciated and if I am in the wrong place please politely tell me where i should stick it..... Yeah I mean post it.
Thanks
