I have an issue with the prusa i3 pro b, this is my first time using a 3d printer, so i'm not so expert.
I'm trying to print an object using the Repetier-Host, but it's stucked on Extruder Heating, and the extruder is stucked at 33°
On the led panel the temperature is 33/210
and for the hot bed is 116/64°reverse image search email checker port checker
What information can i add to know what is the problem?

Thank you

Hello, can you provide videos or pictures?
According to your description, it may be a bad connection, you need to check the wiring.

Hi,
From your display, the extruder is showing 33/210 with the hot bed showing 116/64. This translates as actual temp/target temp.

When powered on your display should show something like 17/210 and 17/64 as the sensing thermistors are reading the ambient temperature of the extruder and hot bed. (Somewhere about 17 degrees.) This before heating is enabled.

Can you check you haven't mixed up your extruder and hot bed thermistor connections as it rather looks like the hot bed thermistor is measuring the extruder and the extruder thermistor is measuring the hot bed. You can check this by heating up either the extruder or the hot bed and watching which temperature increases. From your readings the hot bed is up at 116 degrees when the target is only 64 implying it's measuring the wrong temperature.

Play Bonny!

Hi,
I just finished assembly of my aluminium prusa I 3 and on my first test print x and y are perfect, but z never moved so I was just dumping pla all over and hit e-stop. I ran the print again without filament and noticed my z does eventually step, but much slower than it should.[mcdvoice mybkexperience tellhappystar

thanks,
