Hello again, I've tested the link you gave me, it seems the firmware uploaded correctly.
BUT, when I use the uClient V2.0, it doesnt move correctly(it moves only on axis z). I think I messed up the calibration yesterday, when I was trying to make it work with arduino(I loaded the calibration.ino from the uArm library version 1.6.12, the one you get by searching the library on the arduino IDE).
Is there anyway to recalibrate it in a good way?
I wont touch the uArm, dont want to brake it, I wait for your answer!
Thank You for your time.
