If one object unstick... it is the end of your print ! Now i only print part by part, it s secure !!

So, i have tried a lot of settings.

KO : temp 255°

KO : temp 250°

KO : temp 250° + fan (thread ko, but the rest is good).

OK : temp 255° + fan + speed 60%

With this last settings, the thread is ok, and the rest too.

So for very small part you need to decrease the print speed, but i don't find a "solution".

Like the "edit layer" in slic3r, a new tab will be welcoming ! : > "Edit speed"

So you can change the print speed like you change the quality print !

When you have a small part with hight detail, you can increase the quality and reduce speed for obtain a perfect print !

but the features does't exits.

I tried to change gcode "G1 Fx" but it's imposible... too many G1 in the file :( this must be done during gcode generation !!]]> Others (Archive) ismanu https://forum.prusa3d.com/forum/original-prusa-i3-mk2-s-others-archive/prints-fail-on-small-part/#post-30214 https://forum.prusa3d.com/forum/original-prusa-i3-mk2-s-others-archive/prints-fail-on-small-part/#post-30153 Fri, 14 Apr 2017 15:35:49 +0000 Also, you can print 2 or 3 copies to give each one time too cool.]]> Others (Archive) richard.l https://forum.prusa3d.com/forum/original-prusa-i3-mk2-s-others-archive/prints-fail-on-small-part/#post-30153 https://forum.prusa3d.com/forum/original-prusa-i3-mk2-s-others-archive/prints-fail-on-small-part/#post-30141 Fri, 14 Apr 2017 11:39:14 +0000 thanks i will try !!]]> Others (Archive) ismanu https://forum.prusa3d.com/forum/original-prusa-i3-mk2-s-others-archive/prints-fail-on-small-part/#post-30141 https://forum.prusa3d.com/forum/original-prusa-i3-mk2-s-others-archive/prints-fail-on-small-part/#post-30138 Fri, 14 Apr 2017 11:28:20 +0000 For the first, I would power on the fan after 10 layers or so by such tiny things.

Too hot OR / AND too speed !

i use default prusa preset : 255° / speed 100%

i wil try to reduce]]> Others (Archive) ismanu https://forum.prusa3d.com/forum/original-prusa-i3-mk2-s-others-archive/prints-fail-on-small-part/#post-30136 https://forum.prusa3d.com/forum/original-prusa-i3-mk2-s-others-archive/prints-fail-on-small-part/#post-30132 Fri, 14 Apr 2017 10:51:24 +0000 Too hot.

Give the layers time to cool down.

Printing with fan on after a few layers and/or print slower.

By the way, the thread ist too fine, it will never be a thread.

Maybe it is too small ?

I set :
infill retilinear 20%
brim : 5mm
filament ABS.

and i never arrive to print this stink.

I check all my bolts and nuts, all is ok.

Vibrating ? (The printer is on "concrete")

if you have any ideas !

thanks, great day
