I don't know why the weird layers happen like this every time. First few layers seem fine, then a few messed up layers, then back to normal. Using orca slicer on a Ender3 S1
A little crunchy
z binding
This seems like the right answer, would probably explain other issues I have been having as well. Working on that now
Mainly POM wheels on z axis need to be not too tight and z coupler screws need to be loose (sounds weird but it helps counteract any z wobble)
Thanks, the z-binding was definitely the issue, i had everything on the z axis too tight(the v-rollers, and the z-nuts)
I also decided to calibrate the e-steps at the same time, but wound up screwing that up, and made more problems for myself ( PRO TIP, make sure your calipers are zeroed before using them) but now everything is looking good.
thanks again.
Have you tried printing a macaron to see whether it will look extra realistic
Is the print warped at the edges? Is the texture only on some sides of the print? In my experience I've had the exact same texture when one side of the print suddenly lifts up from the bed (it was ABS, so the extreme warping is par for the course) and with the print being suddenly too close to the nozzle it wildly overextrudes like that. That's why it appears after a while (when it detaches from the build plate) and why it disappears after a while (by having thinner, overextruded layers it eventually compensate the lifting of the piece).
I remember my disappointment when I learned macarons and macaroons were different things. I thought I was getting some coconut macaroons
Wait, what?
Is that the bottom? Backlash on the Z axis could also be a problem. Check if you have slop and maybe get some anti backlash nuts (POM or brass, springs).
The explanation for the effect would be Z tries to move up but can't due to slop so you get all that filament deposited at the same height so it oozes out and looks like a bad over-extrusion.
After Z gets to a certain height and is supported again, it works normally.
Overextrusion. Try reducing 5%
Very few people realize just how tasty 3d prints can be.
If it's not Z binding, consider that you're layer height is too tall for the nozzle in use. if I'm careful, I've been able to print 0.4mm height on a 0.4mm nozzle (yes, that's correct), but I keep layer heights 50% of the nozzle width. If you're printing at 0.3 or 0.35, consider your nozzle may be worn out.
What's the material? This can also happen if you're printing too fast and hot for the material. I've had this exact issue before with ABS, if you're printing in an enclosure with ABS you'll actually need to use the part cooling fan at certain print speeds. It's a myth that you absolutely never use the fan with ABS.
Just to add, the prints looked exactly like this, with normal layers in other spots and this exact pattern in the spots that were too hot.
I'd check to make sure your fan is set to come on at the right time. usually it's off for a few layers to keep things hot and help with bed adhesion, but too much heat will turn everything melted and globby if it doesn't turn on soon enough. if "disable fan for first 20 layers" instead of like 3. Based on things suddenly looking fine above a certain Z, it's not something like simple over extrusion.
g-code preview looks good in the slicer, right? Having a random box with a fuzzy skin modifier would create an effect like this, but would be obvious in the slicer.
Because they are tasty you should bite it
Honestly, maybe over extrusion? Have you confirmed your e-steps?
Ok but... do they taste like macarons?
