Bad quality of impression in some areas and noise

Postby AFTECH » Wed Jul 11, 2018 3:32 pm

Hello everybody

I've got a problem with my Pro2 plus, the nozzle seams to touch the part during printing
The distance between nozzle and plate is 0,25mm and i've got no problem of warping from the plate.
But after the raft impression the nozzle seems to touch and scratch the part during impression making a strange noise.
And when i want to print a spherical part i've got half of the part with a very good result and the other half of the part with lots of imperfections.
I've tried resolutions from 200 to 10 microns and i've lowered the speed and the temperature.
I'm using the OEM filament PLA Premium White.

Does anybody had the same problem ?

Thanks in advance

Here is the gcode for the impression of the sphere in 50microns

Seems you are not currently using the default slicing profile.
Would you like to test once with standard settings profile to see whether the nozzle does the same or not?

Hello thank you for your answer.
I've changed some parameters because of these problems.
The only parameter that i've changed from the beginning was the extruder width that i changed to 0.4mm instead of 0.5mm for the different resolutions.
A higher extruder width gives better results ?
I'm printing the same sphere in 100micron with the default slicing profile right now, i hope the result will be good.

Did you see the video that i've posted ? The noise is a "normal noise" during printing or not ?

Thanks in advance for your help

I've got the same problem on the same area using the default slicing profile.
I also changed the material: ABS instead of PLA and i got the same result and same problem.
I don't understand why a simple spherical part doesn't print correclty and why always on the same area.
