Help Please Small parts printing failures.

cant wrap my head around why I cant print these small parts..

MakerBot 2X
.3 mm nozzle, was a .4 mm nozzle switched to smaller nozzle.

any help would be great.

I have tried slowing print speed etc etc, just cant find the right settings???

Thanks mike

It would be really useful if you could expand on this:

...... I cant print these small parts..

And can you confirm the material?

Sorry ABS filament
sorry

There are a lot of different "printing failures" so it's kind of hard to give advice without more info. Maybe you can write a few sentences about what exactly is going wrong. The more info, the better others can help!

So sorry sorry

Been really frustrated. bad frustrated.... dang

Version 3.1.1 S3D

Ok the settings are set to

Nozzle is set to .3 mm
Retraction is set default.
Layer 0.2000 mm

First Layer 90% Height
First layer speed 50%

Infill 20%

Extruder set to 240 temp

Speed is set to 2400 half of 4800 default speed

I figure that it is a small part 8.2 mm x8.4 mm x 49.7 mm

It lays down the skirt just fine, then puts down the first 5 to 10 layers going good but then stops extruding......
tried to print it at least a dozen times and the extruder stops extruding at various layer heights, between 5 mm and 10 mm
it stops extruding?

Is my retraction over working? its a round part.
Am I printing to fast or to slow?

Thanks

Ok
The MakerBot Replicator 2X, Dual extruder....

Shut it down last night, went to sleep.
Got up this morning, fired up the Printer, preheated the Bed for printing of the parts.
S3D begin print over USB, warmed up extruder, and off she went.
Printed parts just fine, hmmmmm, interesting it was, after 1 hr print job., I decided to try something.
Let the printer cool down, used the infrared heat gun and saw extruders where warm 150 deg F.
After 2 hr cool down. fired up printer to print out 6 more round small parts, in a radial array pattern.
This way they are spread out, so far at 97% and going great, 2 hrs into printing parts and doing good.

So I think letting the motors cool down for a good hour or more is the trick, I think....
Did not change any parameters in the settings, loaded up objects, after I did a radial array in the modeling program.
