changing nozzle

I just purchased a 0.35mm nozzle from seemecnc, What is the instruction to change the nozzle?
And more importantly, What setting do I need to modify after I change the nozzle?
Can I still print ABS, HIPS, PLA, Nylon and wood filled material with 0.35mm?

Well, first, you should heat up our current nozzle and then back out the filament. Use Repetier Host's retract button and retract about 40mm. Once you have the filament mostly out (there will still be some in the nozzle) you can either remove the nozzle hot (CAREFUL) or let it cool. In any case, you want to make sure you are not turning the whole hot end, you might dislodge the thermistor or break wires. I use channel locks to hold the hot end and a 10mm socket driver to remove the nozzle. Reverse to reassemble.
Each material has its own characteristics. I print PLA< ABS Nylon with .35 but never had good results with the wood filament. Normally you need to slow down too. Slicr3 has a nozzle diameter setting. I suggest you read the slicer manual (at their website) if you are not familiar with the settings.
cheers,

Do you get better results with 0.35? Especially if you have thin edge/wall like what I have?

Yes, but it is more challenging to print with a smaller orifice.

great amount of detail on the shell, but man does it take forever to do fill. also consider the tops of your rounded prints, with this smaller nozzle your perimeter is going to be a lot thinner requiring more perimeters or added material to give it a nice closed top!

What is the min layer thickness can I use with 0.5 nozzle and 0.35 nozzle?

i was able to do .1, BUT i cannot tell the difference from .1 to .2 so for speeds sake i usually just stick with .2

You can print at .1 with either, but depending on the filament it can be borderline with the 0.5.
0.1 can look very good, but it can introduce other artifacts that can offset that.
I usually print at 0.2 or 0.15.
