I3 goes crazy and finally bricked..... HELP !!!!
Hi guys.
After lots of successfull prints (pla and abs) my printer goes crazy.
No more Z calibration ans it hits the ground several times.
"show end stops" shows 0 to 1 on every axys (z incluted).
Try to calibrate Z and every thing is OK till point 5 arrives and the nozzle hits the bed. Each time.
X and Y axyes are fine and self test is OK.
Sometimes the printer does a calibration 100mm above the bed and get ready to print....... 100mm above the bed.
Nothing is loss.
Any idea ?
Regards.

Re: I3 goes crazy
Update.
My I3 is bricked.
Try to update.
Link OK
Firmware OK
I pushed the update button and then, : "can't open device"......... Failed.
Pronterface was working fine two seconds sooner.
Now my screen is blue and I can only do "light" factory reset.....
What can I do ?
Thanks.
Re: I3 goes crazy and finally bricked.....
OK.
One more update.....
I tried to flash bootloader.
Com port : OK
Arduino software doesn't see anything.
Everything is Ok Programmer and printer are reconnized by windows.
I think my Rambo is dead.
Re: I3 goes crazy and finally bricked..... HELP !!!!
I don't know much about dead Rambo's, but before that happened, the problem sounded a lot like a broken PINDA cable.
If you get the printer going again, pay attention to the orange light on top of the PINDA probe.

Thanks for your answer.
I triple checked pinda .
If I use a coin during Z calibration, it stops before touching it. Whatever the position.
If I do a usual Z calibration it works fine the 4 first point. But in the center of the bed, the nozzle goes straigh in it. Bing.....
The red light works.
But now the issue is that I can't do anything. I tried with Arduino, USBAVR, using ISP pins, Sd card slot pins...... The printer is bricked.
Is there a way the burn the bootloader ?
Many thanks.
