Mark,

Now setting these low values the printer moves. Not fine because the values are too low in some cases but the problem on the z-axis occurs only when there is normal feedrates set in the slic3r with the Repetier host (take in account that I have saved the various kind of slic3r settings ...

I am supposing the same. Or a problem related to the wrong management of long / integers during compilation, wrong casting or similar. Now I am doing a counter-test:

Set the slicer feed rates to almost absurd values, like 1 and 2 Then the result in the generated gcode is between acceptable ranges ...

No matter about the slice software, I have tried with Cura sllicer from inside Repetier and there is no problem at all.

Then also sending manually the specific gcode command, the effect is just focused: the parmeter F=4800 that internally of the marling firmware (marlin_main.cpp) is processed as ...

Hi Mark,

thank you for the suggestions. I have uploaded the firmware after a in-depth check for all the parameters accordingly with the hardware features. Then I have also changed the name of the firmware.
After the upload I have manually powered and set the prusa with repieter: unfortunately all ...

in the meantime ...

Hi Mark!

Thank you for your suggestion. Frankly I have not yet checked. Please can you advice me where I can find the jumper settings? In the Geetech wiki ?

Cheers, Enrico
