How to swap your 3D printer's nozzle - 0.4mm to 0.8mm Nozzle Upgrade!

With such a large print area, a larger nozzle is helpful for reducing print times to more... reasonable durations. I show just how easy it is to swap your printer's nozzle, and try out a new 0.8mm nozzle!

I just switched my nozzle on my cr10 from .4 to .8 and my prints are failing like crazy and the lines are so big. I am new at this so any help would be appreciated.

[@laharl2k]

use a 0.6 nozzle, the bottleneck is in the hotend, not in the nozzle. With a 0.6mm nozzle, at 0.45mm layers height and 0.7 line width your max speed is 70mm/s unless you want to go high temperature and crank it up from 218 to 230-240ish which then you can do 90mm/s (28mm^3/s)
Unless you only print big stuff, 0.6mm is way more general purpose than 0.8.

Yeah, i found I had to print PLA at 230 to print 0.5mm layers and have it bond the layers well. I have a few other printers, so I wouldn't be opposed to having this printer be dedicated for large format prints. But, i think you are correct and that this hot end would be bottleneck. Doubling the nozzle diameter is 4x more plastic to melt, it's crazy.

Can someone help I changed from a 0.4 to a 0.6 nozzle but I'm having trouble with the layers separating prints come out perfect just have problems with that

[@didtoknan8128]

Have you increased the temperature ?

[@lfrdo7815]

Edgar were able to solve that problem??

"Adjusting the Z axis isn't that bad" It is when the z-axis adjust isn't in the menu system and you are so new to 3D printing that you don't know what you are doing :P
Im trying to find out how to change the z-height offset but every video I find glosses over that bit as if no one ever is new.

[@Anyone700]

You just move the endstop and re-level. Not sure why you are trying to complicate things.

That's a lot of "So's"

Those are very crappy nozzles you got for yourself.
You should avoid being cheap on nozzles as this small part have the most impact on resulting quality, and especially on quality to price relation.
Try TriangleLab ones, they are awesome.
