Hi
Have used my Mono Mendel one year time without problems.
But now when I press the print button begins the table temperature to rise.
You can not turn it off with printer interface, I need to turn the power switch off.
Can´t se any burned parts on the PCB.
I have checked the temp sensors and they seem to work as they should.
Tested according to the instruction

reprappro.com]
The first time the error noticed was when I printed a fairly high detail.
When I try to lower the table temperature, but it began to rise instead.
Thinking if I buy a new circuit board and cause of the error is still there,
and the new one crasch to.
But clearly if I replace hot end parts too so should not be the any foult remain.
The PCBcard is called Mono Mendel Revision: 2013-05-08
Is there something I can take another look at.
