Prusa i3 shut down during printing

Post by pat51 » Fri May 19, 2017 1:34 pm

Hello everybody,
I still have an acrylic Prusa i3 and start printing less than one kg of Pla
My problem is : When I launch a printing from sd card, the temperature grow normally to reach good one ok
The start printing begin and depending, about 15 min or much more, Prusa i3 shut down it mean LCD out, engines out an I have the green led on Supply)
after few minutes, re start
I saw some people putting external fan to electronic, ( with external power) but shut down :-(
I change also electric source 220V but shut down also
Can you help me ???
Thanks

Sounds weird,could you take a video showing how does it shut down and restart?
-Keep your mind and try to test it. :)

Does it restart on its own or do you have to switch it off and on?

The PSU specification states:
Overload protection: 105%-135% hiccup mode, auto-recovery

Over-voltage protection: 115%-135% cut off the output, auto-recovery
Sounds like the overload or over voltage is kicking in.

Spec here: https://www.geeetech.com/s18012-12v-15a ... p-919.html

I'm not sure what you mean by this, what's your country's mains voltage?
If it's 110v and you switch to 220v the PSU won't work properly. if it's 220 and you switch to 110 you'll blow it up! :shock:

Check your wiring and ensure that the hot bed and extruder terminals are tight. Check the PSU output voltage.

Does it always fail at the same time on the same print? Could be a short circuit when the X,Y or Z axies flex the cabling to a particular position?
Can you force the failure by flexing the axies cabling by hand?

Does it always fail at the same time on different prints? Is it time related?

Hope this helps a bit with the diagnosis :)

Play Bonny!
