Print is taller than nozzle while printing

[traxon]

I'm using a 0.4mm nozzle right now, and funny you mention that because when I was priming the nozzle, extruding into the air, I was thinking the same thing - it looked slightly wide. I wonder if the nozzle is messed up - I just use the cheapest nozzles from china - maybe they just suck sometimes. I have my extrusion width set to 0.4 right now; normally I use 0.48. Both seem to work ok, but 0.48 seems a little better in my opinion.


I think I maybe just figured out the problem though - lack of part cooling. I switched to different filament, and I got the same massive warping, then I printed the same file again with a small desk fan aimed at the nozzle - much better! It's not finished, but I don't see any crazy warping so far. So maybe it's just lack of part cooling, OR, maybe it's cooling the print bed. I typically set it at 65-70 C (which is roughly 8 C cooler for me on the surface of the glass), which is a bit higher than some people use (50-60 C).


The thing that's weird, I've never had these issues in the past using higher bed temp and no part cooling, so why now? Maybe a difference in thermisters? In any case, I guess I will add some sort of part cooling before I pull any more hairs out. Might also try reducing the bed temp a tad, and swap nozzles too since the one I'm using seems questionable. Thanks!

I usually run a width of .4 ~ .44, An have have always used the cheap brass nozzles without any troubles.
And hope we are both talking about PLA. I generally set my Nozzle to 196 ~ 202C and the bed temperature to 40 ~ 56C
1st layer no fan all others layers 50% fan speed.

Can you verify the Nozzle size by looking to see if it has an imprinted number on the nozzle. Some of my nozzles do and some not.

I have had them send me the wrong thermisters in the past. If you look and the Last picture in your 1st post.

You can see that the lines are spaced apart like you have a .4 nozzle and your slicers settings are set for .8 nozzle.
Then you have compensated and somehow got the CR3D.XYZ Benchy to somehow print.
