Geeetech

When i try to compile te firmware it stucks with message: Looking for LiquidCrystal library in registry
Any suggestion?

Dear vert,
i've solved that problem.
I've an A10M printer and i would like to know if i must use the two configuration files in the root of source dir or i must use the files of A10M in config/examples/geeetech directory?

Thanks

Thanks, I'll use the one provided in marlin dir

dear vert,
i've comèpiled and installed the firmware, but the printer, when i try to homing, moves in the upper right corner instead of the lower left and then emits a strange rumor and the lcd says homing faied reset printer.
can you figure out why?

how can i define the right drivers?
how i can correct this?

I resolved xyz motor problem because were nont defined stock. Now the axis motor works well, but extruded motors work inverse. Positive extrusion values retreat and negative extrude. I think I must follow your example and invert only e0 and e1.
Right?

i'm not sure i've understood your last reply.
sorry would you explain me?
