Ripples on top surface?

Ripples on top surface?


What's causing the top layers in the attached image to ripple? I've seen it before on the first layer, but that is caused from the nozzle being to low.

I'm using the supplied scli3r profile. I've calibrated my extruder so I don't think it's over extruding.

Printing with PLA, correct?

I think ripples may be cause by filament not cooling fast enough, are you printing with an enclosure and if so what is the air temp.

What vendor makes the filament you are using?

Do the ripples appear when you print the batman gcode on the SD card?

I'm printing with PLA but no enclosure, PLA is made by prima. I've printed a lot with it so far and it's been good, but this is the first time I've used slic3r, I've always used S3D.

I'll try printing the batman and report back.

Re: Ripples on top surface?

We are looking at layers 1 & 2, correct?

My guess: since the 1st layer looks great and the 2nd layer is showing ripples/waves, I'd look into over extrusion starting at 2nd layer or maybe in general e-steps calibration once more. Is your nozzle perhaps a bit high and therefore no problems on first layer?

Just my 1 cent worth ( is 50% off today since I am guessing). I suppose printing one of the pre-sliced models from the sd-card will tell more.
