SUP W/ THIS!?: Odd "ripple"... Same thing on two printers (same make/model).

Tip: grab some calipers and measure how thick the first layer (including curls) ends up. It should be exactly your configured first layer height.

Good idea:) Thx, @Thomas_Sanladerer . I’ll do that when I get in…

This is definitely, unquestionably too much nozzle gap. (This kind of squiggle is really common with the first layer of rafts. Your first-layer settings resemble a raft layer.) The slicer is trying to push a quantity of plastic that is supposed to ooze out sideways (extrusion width > nozzle diameter) squeezed between the bed and nozzle tip. But your nozzle/bed gap is greater than nozzle diameter, so the plastic “noodle” jumps out in sideways ripples instead.

You ever make a soft-serve ice cream cone? The extruded “noodle” flops around under its own extrusion force. Your ripples here are basically the same thing.

I believe his settings do say rafts are turned on.

@NathanielStenzel The raft below the print shows squiggling (really common) and the skirt around the raft also shows squiggling (less common because you don’t normally have that high of a flow rate during skirts)

And now it has been going long enough that the live feed video is worthless.

UPDATE:

  • First, THX ALL! Great community. Very helpful, and very prompt. I really appreciate it.

  • In spite of the “oddities”, the print came out very good. (See photos in subsequent posts.)

  • Seems the “squiggles”/“noodling” is “normal” for the way things were sliced. I will have to revisit the manufacturer’s recommendations on first layer settings - as a skirt, +/or a raft may affect things. ( @ThantiK )

  • FYI, for max. resolution, a 0.100 layer height was chosen, while a 0.250 first layer was forced, and at half speed.

  • Also, the mesh minimum was slightly raised above the bed to improve a situation encountered in a previous print attempt. It seemed to help, actually.

  • Running a second print, w/ same settings, on same machine…

  • Prepped machine to ensure best configuration: sanded acrylic base plate for flatness and roughness (for grip); did ‘Auto Bed Mapping’, and z-height adjustment (‘Nozzle to Bed’); loaded new spool; treated filament tip w/ canola oil, manually primed nozzle, and ran test print (stretchlet)… got very good results:)

  • Set up hi-res time-lapse. Also, while it’s printing, watch livestream at http://www.tinyurl.com/Factur3DLive.

  • Let’s see how things comes out!..

OVERVIEW of the scythe (w/ penny for relative scale; fyi, length is 100mm). A little stringy, so cut most off, and pulled/rubbed a bit. May give a quick heat blast, too.

CUPCAKE TOPPERS! For kid’s bday party. Printing 16 of 'em… scythes, not kids :wink: :smiley:

Well, 16 kids will get a RWBY scythe takeaway:)
