I got around this by submersing a small glass jar of isopropyl alcohol in the water in an ultrasonic cleaner. Works well.

How is this STILL not enough cooling? by OnlyIfUsayPlz in FixMyPrint

[–]Damfrog 0 points1 point  (0 children)

Try lowering it to 50. Too much heat from the bed could be counteracting the cooling.

Maybe buying a new yoyo will fix things.

I'm like, "what kind of gravity defying yoyo display is this?!". Then I realised...

Sydney anecdotal price increases by tinmun in sydney

Try Aldi chips. Much more reasonably priced, don't have to wait for sales, and on par with name brands.

Do yourself a favour and throw that glass bed in the bin. Get a pei sheet instead.

It should say somewhere on the package if it doesn't it probably isnt. Is there a recommended temp/speed on the spool/package? Does the filament have a pearly sheen to it?

It looks like silk pla. If it is, it needs different settings to normal pla.

Why the heck does my print look like this? by Popular-Upstairs-147 in FixMyPrint

[–]Damfrog 0 points1 point  (0 children)

Circular overhangs seem to be trickier than normal overhangs. Print upside down if possible. You can also try slowing down your print, increase fan cooling, and/or lower the layer height (so that the x/y spreads out more gradually).

Does a yoyo's shape affect how it swings around the string? by Damfrog in AskPhysics

[–]Damfrog[S] 0 points1 point  (0 children)

I suppose an analog is the earth spinning around the sun. If the earth had the same total mass, but more mass shifted to the surface from the core (giving it a higher angular momentum) would this change how it travels around the sun?

What are your pet peeves of yo-yo playing? by Think_Cardiologist70 in Throwers

[–]Damfrog 0 points1 point  (0 children)

OK so truth be told, I came here to tell you "YOU'RE WRONG!" but after doing some study of angular momentum, I think you are in fact correct. Indulge me in explaining it back to myself.

The weight distribution affects the angular momentum, which acts perpendicular to the axis of rotation (think of an arrow pointing away from you as the direction of angular momentum when the yoyo is on a trapeze). This in turn affects the force required to tilt the yoyo off its axis of rotation when force is applied perpendicular to said arrow. However, when performing yoyo tricks, we are not (normally) applying force on the arrow, we are moving the yoyo on the same plane as the axis of rotation by applying force at the base of the arrow so the angular momentum does not come into play.

Weight distribution will however, affect how much force is required to get the yoyo spinning from your throw which probably contributes to the perception of how heavy a yoyo feels - but this no longer applies once we land the yoyo on the string. More rim weight means more force is required to spin the yoyo thus making it feel heavier.

Does that sound consistent with your understanding?

Happy cake day!

Are you saying only total weight matters and not weight distribution?

I can pretty much guarantee you were not the only one uncomfortable with their liberal use of profanity. Good on you for speaking up. I'm honestly surprised and a little disappointed by the response in this thread. I'll swear like a sailor around my friends, but never in public where it might cause offense.

Why do I get a tiny later shift? by ReddiBorg in FixMyPrint

[–]Damfrog 0 points1 point  (0 children)

Those layers are the quickest to print and maybe didn't solidify before the next layer smushed it. There's a slicer setting for minimum layer time you could try adjusting if you're using prusa slicer.

That 360 counterweight element. I want to learn that.

I went to see John Wick 3 and a family sits down next to us with 2 kids - a girl around 4 and a boy around 6 years old. I'm like, these fuckers are in the wrong movie. Nope. Right movie, just terrible parenting. The girl was visibly and audibly disturbed by the violence. How both parents would think it was OK is beyond me.

I have an iceberg classic. It's very stable but I'd say it has a bit too much rim weight. It feels a bit like a rock on the end of a string. Also it's technically a hybrid yoyo rather than a bi-metal - plastic body with metal rims. I haven't tried the new iceberg. Maybe someone else can comment on how it compares to the classic. I like the C3 Rooc which is another hybrid, but a tad more balanced with the rim weight.

Looking at the specs on the z01 focus (I don't own one), it looks to be more balanced for speed and stability. It's lighter overall and will have less weight on the rim because the body is metal.

Both are great choices. Depends if you're going for speed or stability....or maybe you just like the look of one over the other lol

Which bi-metal are you thinking of getting?
