Hi there,
looks like I need to put my hands on the firmware.
I have replaced some of the drives and also I noted that the extruder needs calibration but the board is not set to accept changes from Repetier. So I am without alternative than to reload the firmware and I do not have the original one. The printer is old and the seller does not have it too.
I went trough the various options and many of the options are understandable but I am not sure.
Can someone please give me a hand?

Well, having dealt with several people with these boards my suggestion is just to upgrade to a GT2560 and work on that.
The sanguinololu isn’t widely supported and the last time any of the driver software was updated was back in 2012. It’s just a huge hassle to get set up to edit the firmware unless you already have everything in place.

I’ve got a Christmas Huxley sitting next to me running Marlin on a Sanguinololu right now. It’s not the most recent version, but I can send you the config file. This won’t have the correct settings for your printer, but might help you get started.

A good starting point can be found at Marlin - RepRap
Also in the configuration.h file of the firmware you’ll find a list of other resources, specifically
I’d suggest taking the time to watch the you tubes, read way more than you think you’ll need to and then start working on it. Without a copy of the originals, you will work on your printer just like it was brand new and need to figure out all of the values. It takes time to get it right, but there’s nothing too bad about any individual step.

If you can send it M503, it should output all the firmware configuration settings. you can use that information to configure a new marlin from source code.

Thank you a lot. Now I have a starting point.
Really apppreciated.
Thank you! That may help. My printer is very similar and would allow me to have a starting point.
yes please send it.
You will also need to put a sanguino file in arduino’s hardware folder and replace an ini file for arduino to be able to compile and upload to saguinololu. Sanguinololu - Geeetech Wiki That page has a link at the bottom of the page, also instructions.

Thanks for the nice compilation of references. Now that I learned that with the Gcode I can get the actual settings from the board, i will give it a try.
I had to chop up the code a fair bit to get it to run with auto leveling and a LCD If you want I can pack up my firmware folder and share it or maybe I should fork it
Hi if you do not want to touch the firmware but you need calibration you can set it the appropriate command in the start g- code . It is M92 X(your x steps) Y(your y steps) Z(your z steps) … For example I have M92 X160 Y160.5 Z2560 E93 *35 Hope it helps…

Just for clarification my sanguinolulu has a 1284p in it
After several hours trying to set up the environment, i got your point.
