Cant upload firmware to 3d printer

[Fjed]

Hi, i have mounted a autolevel sensor and i try to edit the firmware as it says in the sensor manual. But when i try to upload the firmware to the 3d-printer, i get an error, it says something about servos was not declared in scope... i have not touched anything else in the firmware... what can be wrong? Can somone send me a firmware for the geeetech prusa i3x with autolevel built in the firmware?

Hi,
You can download the modified firmware for your I3X from this post:
viewtopic.php?f=27&t=18263
And remember to use Arduino 1.0.1 to upload it.

i think that file is gona work, but my problem now is that it comes an error when i try to upload it, it says avrude: stk500v2_RecieveMessage(): timeout
can the problem be tha i am using a mac? i have tryed to upload with a windows pc, but my problem there is that i cant open the files in arduino... i have tryed everything, tryed to drag the files over to arduino 1.0.1, but it does sat no files were added to scetch.... i dont know what the problem could be.

was your printer connected to Repetier HOST at the time?

if so shut that program down- you cant upload a firmware while the printer is being controlled by another app.
