Unresolved Problem with solid infill using E3d V5 hotend with 0.25 nozzle

Hi!

I upgraded my roboprinter with an e3d V5 hotend. When i was printing with 0.4mm nozzle everything worked fine. But now i changed the nozzle to 0.25mm. I configured the nozzle in printersettings and i used the right settings in SLIC3R. (Screenshot)

Everything is working fine (outlines, nonsolid infill,..) exept solid infills. For solid infills the printer extrudes much to less filament. (nearly nothing)

Edited:
I tryed to print 0.1mm, 0.2mm and 0.25mm layers with different tempretures (190° - 215°) using PLA.
Heatbed @50°

Always the same problem.

Has anyone an idea what i can do?

Thanks in advance!

Can you post a picture?

 

Thx 4 reply.

@mark: I tried to print only a bit slower than default. Will try to slow it a bit more down and test some diffrent settings with extrusion rate.
@Printed Solid : Yes, i testet a view different Settings, but i will test some more. My feeling was, the smaller the value, the bigger the problems. But maybe it works in combination with other Extrusion rates.
@Mike: Will take pics at the next tests. (not sure if i can test it today)

thx guys!

 

Hi,

I also had real under-extrusion and hobbed bolt slipping/polluting problems the past days - for me the final solution was so close but it took days to recognize it... I printed different PLA at max. 215 degree celsius - at higher speeds at 30-50mm/sec. then the underextrusion problems at 0,2mm layer hights.

Since I print now at 230degree for speeds>30mm/sec. all problems gone... and a very good print quality even at 50mm/sec. print speed (E3D V6 hotend, 0,4mm nozzle)

Try again at 225-230 degree celsius...

 

now i've tryed many new settings according to your tips. Quality got better. But then i recognized that my heatblock is loose.
so i tightend it again ... and maybe damaged it, because it looks crooked...

damn... Need to tear everything apart... :/

 

They are over loose screws. He installed an E3D
