Iff you get it to upload once it will give an error message the next time as the upload is in the Arduino memory , confused me to a few times .

PeterE:
Hi chipenter,

Aha, so that's why! That is something I have been thinking a bit about. A thing that is different between different hardware and applications. How does it react to repeated uploads? Is there an automatic write-over function, or do I need to empty a memory? Seems like I am close to this one.

Will have to study the behaviour of the Arduino a bit more. It is way different than a Raspberry Pie.

PeterE:
A lot of reading done and new things learned, but still no activity from the printer. :bang:

It seems like there is some SW bit missing even though I have downloaded all that I think is supposed to be in place according to descriptions.

I even tried to make a configuration on the MarlinKimbra site and not even that one worked. The filed uploads all right (I think) but when I switch power on nothing happens and I cannot get the PC and printer/Arduino to connect. It says connecting ... but nothing happens, and the Pronterface SW does not open so I can manipulate the movements for calibration.

In a way I am stuck and have a hard time finding out why it does not work. I think I will reinstall all SW from start to see if that helps.

This is going to take a loooong time to get going. :palm:

chipenter:
Have you tried Repetier Host it comes with all the Python files to instal in one , in Marlin config h you need to set the board , port speed , end stops , pull up resitors and temps .

Hi PeterE

With Marlin installed you should be able to control all the printer functions from the graphic display. No other connection to a computer/slicer or anything else is needed. The motors will only power up if you just tell it to home in Marlin. Only the Marlin firmware is needed to get this far - and in fact check out the whole machine. When you turn it on does the graphic display show any error messages. I got caught out with the mintemp message when a thermister was not connected, as once that message shows the whole system stops.

If the display is not working you likely have power supply issues. Generally, the display will come alive with just the power from a usb lead. No display likely means the ribbon cables are reversed.

Hope this helps

Best Regards
