Just put together a chinese Prusia i3.
Got it printing, But I have burnt out 3 (J-head) hotend elements in the last 3 weeks, and only printed out 6 test box's.
What have I done wrong?
This can't be normal. Please help.
Info:
Using pronterface
3 different J-head hotends
thermostats seems to work
I think I may have seen it get to 301 before heading back to 250?
