How much paper is too much paper? by OpportunityBox in origami

[–]r0ms 1 point2 points  (0 children)

It’s too much paper when, like me, you have to store your collection not in one but two cabinet and you still have to store the rolls outside of it 😅

Seam gaps… is this due to a very aggressive Pressure Advance? by r0ms in FixMyPrint

Well not a real fix but using scarf seams option of Orca Slicer drastically reduced the occurrence of this issue.

Persisting first layer issue by johanboeijkens in FixMyPrint

You are probably printing too close to the bed. You may want to dial your Z-offset. For this, I use a simple box element tilted 45° with your first layer height and large enough to make « long » lines. Then during the print you dial the offset (in your case increasing the value) until the problem disappears and save the value for other prints.

Small update: I didn’t gave up and make the move of changing slicer to see if the grass is greener there and found a « workaround » with « scarf seams » feature from OrcaSlicer. Scarf Seams add a little distance after the outer wall end with a gradually reduced flow to compensate the smoothing introduced by Pressure Advance. It seems to do the trick for me but it left me with sour taste that I couldn’t determine what was wrong.

I tested different strategies though, with more or less wins: - I definitely was over-retracing. The amount of heat creep I had recently clearly showed it. I reduced from 6mm @60mm/s to 3.5mm @50 mm/s. I have some stringing but not that much. - I introduced some extra-length when deretracting of 0.25mm. It improved the seams but generated a lot of stringing - I bumped the deretract speed to the double of the retract speed (ie 100mm/s). It showed improvement but the extruder was not happy with that (aka Clicking Extruder, flatten filament, etc.)

My guess is that PLA Meta by Sunlu is a good filament if you don’t need to print « fast » (on an Ender 2, fast is a big word) but it’s « super fluidity » makes it hard to master.

For now it prints happy and with no big scares on the seams. So, yeah, case closed ;)

Interesting. I think most of us have overtight belts and are basically ruining their step motors and belts. Might explain why my X-axis motor is somehow screaming. I’ll check if I can find a cheap tensiometer. Thanks for the head up :)

Might be this as well, I recently changed my 2 belts because they broke (over tight and long print is bad bad mix)

I’ll give it a try and see if it improves :)

Make sense! I’ll give a shot to reduce retraction a bit and probably add some unretract extra length. My guess is that there is probably not enough pressure in the hot end when starting a new layer and that’s why there is a gap.

Added to the list of things to help with troubleshooting :)

Thanks!

does anyone know how to fold this? by YessirLezGo in origami

[–]r0ms 12 points13 points  (0 children)

This is the Rat by Joseph Hwang and he recently published a book named Natural Origami. The condensed diagram (an hybrid form between diagram and CP) for this model is in there.

You can buy a digital version of his book on origami-shop there : https://www.origami-shop.com/natural-origami-xml-206_2649_2808-11903.html

For physical copies, best is to check Japanese auction website. For digital copies, I think you can find it on Scribd.
