V4 .5mm and .75 mm nozzles

[jcspball13]

Finally upgraded to the v4 extruded; wow what a great upgrade

Question here: I need to print a few parts a little faster; current part takes about 4 hours and I need to cut that firm

I had a .5 mm on my v3b and it worked great.

Jus wondering if I can safely us a .5 to increase speed; is it ok with petg?

And is the .75mm an option? Does the printer push enough filament for the .75mm to work?

Thanks guys! Loved my m2; even more with my v4. Great work makergear!

I would guess that melt time might be a limiting factor, so you might not be able to speed the printer movement up as much as you'd like, but you could go with a higher layer height, and that is going to speed things up considerably.

.5 is no sweat. .75....ehhh. i wouldnt bother. atleast on my e3d, anything above .5 and as jules said you are limited with melt time. basically you can put a .75 on but then you need to slow down the print speed because the hot end cant melt that volume of material fast enough to squirt it out the nozzle.

That is what I thought; thanks guys, love you and this community!!

Just a side question: would you guys buy a nozzle and change when needed; or am I better off have separate complete hot ends so I don't screw anything up?

Remember to be very careful when you remove the nozzle on the V4.....you have to take it out of the clamp and do not twist the thin neck on it to remove the nozzle....they tend to break.

I keep at least one spare hot end for the V4. (So for the that reason, I'd go with the whole hot end over changing the nozzle.)

Ok, good advice.

I am guessing the v3b .5mm nozzle wont work for the v4?

Nope!

Using smart print profiles tends to be the biggest speed factor. If I need a print fast I would use the following settings.

.35mm nozzle
.3mm layer height
.6mm layer width
single shell/perimeter
0-35% Rectilinear infill (Optimized for the part)

How about for a .5mm nozzle?

Or a .5mm nozzle with PETG; any suggestions?

0.4 layer height and 0.8 layer width is the furthest that I would go with PETG on a 0.5mm nozzle. any more you may have trouble keeping the hot end up to temp.
