Second Benchy print. Increased the retraction to 1.5mm but didn’t have much effect. I’ll try a much higher retract next.

This was 0.10mm layers.

I’m getting more of the weird layer stuff just on the one side, incidentally it’s the same side and direction of the part as the other one I noted in the video I posted, I think it’s a similar type of issue?

Try a little hotter on the hotend. I run PLA at 225 on my E3D V6. It might help your retracts to be more effective.

Also have you calibrated your extruder for length? Also calibrate your extrusion multiplier via the perimeter only cube method: compare theoretical extrusion width to the actual extrusion printer output (two perimeter at 0.5mm extrusion width should be 1mm thick wall… Adjust extrusion multiplier until it comes in to dimension averaging the four sides). I mention it because it looks like you are under extruding a bit.

@Eclsnowman best place to upload the fff?

@jerryflyguy do you have Dropbox or a Google drive?

Nope but I’ll give Dropbox a go

@Eclsnowman tried this two perimeter test, getting about 1.15mm walls w/ 0.50width and .95 multiplier. Best way to adjust this is to keep dropping the multiplier? My filament is measuring 1.73 (as best as I can measure).

Any links to a good description/how to of doing this test?
(Will post my FFF tonight)

@jerryflyguy This one is pretty good. But I like two perimeters versus 1:

@Eclsnowman

Should be the link to my FFF file? [new to this stuff :slight_smile: ]

@Eclsnowman how does the wall perimeter overlap factor impact this test? I just noticed mine is set at ~15%

Wondering if a single perimeter print isn’t a better evaluation of print width as it applies to extrusion multiplier?

I tend to run more like 18-20% depending on the characteristics of the filament. Some plastics tend to have more or less die swell after exiting the Nozzle.
