Perfect, thanks. Might not be able to have a bash at this for a couple of days but will update with anything I manage to do.

Certainly will. Serial 3 looks like my ticket, 2, 3 + 4 is all that's needed. Can you post the full image for me, can't seem to find it...

I would like to attach a comms cable (232) to my UMO+ so that I can monitor it's status and maybe trigger commands. This (I believe) is essentially the same as the USB connection, but I am wondering if some of the spare pins on the motherboard can be used as a Tx and Rx... Has anyone done this or have any idea if it's possible?

Ah, maybe not... I have an Original + I'm a noob to this so not sure what the differences are or even if the pin outs are the same...

Not made a hex file but here is a zip of the Arduino files. If you don't already have it, download and install the Arduino software, Open "Ultimaker_Original___EXT_2_Only.ino" Set the board to "Arduino/Genuino Mega or Mega 2560", Select your com port, Then compile and upload... that should do it.

I made a version of the firmware that now works using extruder port 2. First print in progress! Thanks to all who have helped. @goldenidea, I'm not 100% sure yet how I make this into a hex file, as soon as I work it out I will post a link for you. Going forward I would expect my board to be replaced as it's everything points to it being faulty...

Might have spoken a little too soon. That firmware isn't right, it does allow me to test that extruder port but it's really not happy doing much else. There is no head bed temp display and the heating of either bed or print head fails. Not to worry though, don't expect you to muck about any further. Going to look into how you edit firmware and see if I can sort it out. Thanks again

Legend! That's done it, I can control the extruder motor using Pronterface so think I'm going to do a test print. For anyone else reading this in the future, I also had to move the temp sensor connector over to "Temp 2" otherwise you will get "ERR: MAXTEMP BED" So it does look like that port is dodgy but at least I can start making some plastic mess while I wait for a replacement. Thanks a lot for your help. Matt

Yeah, might have to go down that route but I was hoping it would be a good quick test to see if port 1 was borked. I've tried another firmware as gr5 suggested but still nothing... I'm starting to think it might be a board issue. :(

Thanks

Thanks for that. I forgot to mention that I did try the M302 command and also just heated up the nozzle to make sure it should work, neither did. Going to try out a builtmaker firmware...

Hi, total 3D printer noob here! Just got myself an Ultimaker Original +, built it and 99% working. But, when I go to print the extruder doesn't extrude. One Job.... So I've done some trouble shooting. If I plug the extruder motor into the X axis socket and send move commands it works, so the motor is fine. I've installed Pronterface so I can test the extruder motor but it does nothing. I wanted to try to control it in Extruder port 2 but can't seem to find a G Code for the 2nd port. Either way, it seems like Port 1 isn't doing what it's supposed to. I'm using the most up to date version of Cura which uploaded the default firmware. I've tried using http://marlinbuilder.robotfuzz.com/ to build several different versions of firmware but when I upload any of them, they seem to upload fine but once complete the Controller display starts to display gibberish.... Any ideas?!
