Help with retraction settings

[orm255]

The pits look like you;re retracting to much filament. How many mm have you set your extruder to retract at and what speed?

You will always get retraction marks no matter what. Looks like you have your seem position set to Random. Try set it to Aligned or nearest. One or the other tends to chose a corner as the retraction point which makes it less visible and more hidden to a place where people may not look at if its something thats on display.

The current settings for retractions are:
Distance: 2.00 mm
Extra Distance: 0.00 mm
Vertical Lift: 0.00 mm
Speed: 30.00 mm/s

The starting position was set to optimize for fastest printing.
Should it be set manually?
If yes, then what would be a good location (x,0 / y,0) or center of build plate?

Is there any particular reason you have your nozzle diameter set to 0.38?

The center location to start the print is the best option as you get the best levelling in the center

I seem to have forgotten to change it to 0.4 after setting extrusion width to manual. It was set to automatic at 0.4mm which automatically changed the nozzle diameter 0.38 for some reason.
Also, I meant to ask what would be nearest appropriate position to avoid visible seams on the print?

The first thing i would do before anything is set your nozzle to the correct size as this will cause you all kinds of issues, especially when it comes to printing wider layers and leave your extrusion width to auto. there is rarely a need to change any of this if your filament has been measured correctly and your nozzle size has been set correctly.

The only thing you should ever need to change to calibrate your filament is the extrusion multiplier. This gives far more accurate prints than changing other sizes to work out the correct filament dimensions.

I dont know of any way you can change the extrusion position to pinpoint to an exact location to retract, but i will be made up big time if anyone finds a way to do it., but an extrusion of 2mm set at speeds of 40-60 works best for mine. This is something that will be different on every printer im afraid. Ive found fasrer retraction speeds work best on mine.

get your filament size right first as being out by even 0.5 can cause catastrophic defects.

Any advice or tips on choosing the correct nozzle size?
