After several days of testing with Shield Protoneer 3.0 + fw GRBL 1.1f, perfectly working, I decided to test the modified fw 0.9i for Servo on Z axis and the first problems started ... the Y axis stopped working and after several checks on the cables I realized, through a small control sketch on the digital ports, that the digital pin 3 of the Arduino Uno, the one that sends steps pulses to the Y driver, no longer works. AtMega328 burned or recoverable?

It is possible a power return in case i have moved the Y plane manually? Probably the digital output 3 is burned out  :(

Hi,

What model Arduino do you have?
Has it got the DIL type controller IC?

Everything runs on smoke, let the smoke out, it stops running....

This one...



Probably the digital out 3 is burnt. I have already ordered a couple of spare atmega328 that I will reprogram via ISP with the bootloader...

Thanks
