Calibrating the extruder was the missing step, thanks for save dc42!

I have not, i must have missed that step during the initial setup. I'll calibrate it and report back the results.

Hey all,

These are my first prints and they are coming out super jagged. I've tried messing with different extruder speeds but it doesn't change much. My Delta moves super quick when printing. Not sure if that is the cause… anyways. The prints are below. What does it look like to you?

Here is my config file if that helps.

Just to confirm, it was my thermistor. I replaced it and it heated up immediately. Thanks for the help everyone!

@T3P3Tony:

The Hotend PCB is on Github here:

It certainly sounds like a new thermistor is the most likely.

Awesome, I'll start there. Should i replace both wires coming out of my hotend? or just the thicker red one?

Does anyone know where i can find the hotend pcb? I tried looking on the E3D website and the Think3dprint3d website but did not see it.

Was also wondering this…since my hotend pcb still powers on my 2 fans connected to it...is it safe to assume that it's ok? I'm now thinking it's just the thermistor that needs to be replaced..

So i measured the pictured black and green wires and got a resistance of .010 when the mm is set to 2M. Hope that's normal.

I measured the resistance of the thermistor plug (link to picture in a previous post) and got the same .0l reading.

Thanks for all of your help so far everyone. I'm a total noob. lol

@T3P3Tony:

Sounds like you have a faulty thermistor or faulty wires between the board and the thermistor on your hotend.

Ok I'll look into replacing the thermistor. Is it possible I blew that little board that sits above the hotend? The one i plug everything into.

I ended up stripping the wires just to be sure. Still same error message.

@dc42:

You could put wires in the connector holes and measure between those.

I put wires into the holes as far back as i could and measured but still get a reading of .0L. Perhaps i'm measuring it incorrectly? I used speaker wire and made sure to stick them in as far as they would go.
