Hi picclock,

Oh, I understood. So, I decided to do some classical fault finding to see if the thing is burnt or not.

As I said, there are some LEDs are lit as they are supposed to.

The ones to the left inside the red ring are the Tx Rx LEDs and they work admirably when something is uploaded.
The single one inside the red ring to the right is the Power ON LED and it is either red or orange. cannot tell through the RAMPS board (No, no hole it lights straight through the board!)
In the blue ring we find the reset button! (How can you place that to make it wind up under the board above without any chance to touch it but to remove the board????)

So it appears that the Arduino board is working as it should so far.

With Pronterface running on the PC using a USB cable I can get temp readings but nothing else.

The display is getting power as it lights up, but there is no text or graphics showing.

Then I also noted that the green LED on the RAMPS board (next to the extruder heater connection plinth) blinks twice at power up. So the RAMPS board also seem to work.

When I first uploaded a so called sketch I was able to get Pronterface to connect to the boards. That was when I understood that the temp sensors must be connected to be able to continue.
Then I probably made something odd in the next sketch trying to fix a setting, but from that point the program does no longer answer. I am starting to wonder if I have managed to crash the SW?

Will try to test further. Have installed Repetier on the PC and will do a sketch from there to see if it improves the situation.

Will be back for sure.

Hi Peter E
Think I might have sussed it from your description. Sounds like you have not got the correct display selected in configuration. H. The graphics display needs the u8glib library added to the arduino ide. Not sure of the exact config settings but will post them when I get back.
Written rather badly from my mobile.
Best regards

H PeterE
The relevent section in configuration.h is around line 720. This is the part you need to use. Ignore the white pcb bit. You will need to disable any other graphics settings. Once you have it working you can edit the click controller style in configuration_adv.h. If you want I will post my configuration files tomorrow.

Hope this helps

Best regards

PeterE:
Thanks ever so much picclock. This more or less confirms that it is a SW issue rather than a HW one.

With your examples and suggestions I now have more than one way forward.

A - update the sketch I already have according to suggestions.
if that does not work;
B - Dump the existing installation I have and install a new one. My son found a useful example in wikipedia that looked more complete than my original one.
if that does not work;
C - Try the Repetier path.

I can also add that I had some problems when downloading all the files from the beginning. I was missing both python parts and the u8-thingy, parts that I have downloaded as I found their need.

Well tomorrow will be next step on the way.

Hi PeterE
Copy of known working files attached. You will have to amend the steps/mm settings for the axis and The Z axis endstop state if you wish to use attached configuration.txt file you will need to rename it configuration.h (unable to post .h files) . I called my machine Granite 3D, rename to your preference (Peter the Great ?? :med:). Even without any alterations it will allow testing of the setup. Just unzip the Marlin-RC1_3 file, rename the originial configuration.h file and replace with attached (in the marlin directory). Then connect arduino, open or double click the Marlin.ino file to open in the arduino editor. Select upload, have a cup of coffee while it compiles everything in sight, including, hopefully, the marlin sketch. Once its uploaded you should see the Marlin welcome screen - no need to power it, it will run from the USB lead.

Good Luck

Best Regards
