Getting back on the horse.

[GAD]

It's been around for a long time and it wasn't dialed in until I stopped working. So now, it's another tool in the quiver.



It was a gift. Funny, it was too little adhesion that was the issue before, and it's far too much adhesion.

It could be as simple as the temp being too high so it’s coming out too liquid on the first layers.

One of the things I struggled with when learning was that every brand has different temp zones. This variation is why I stick to one brand where possible.

Sometimes even a different color from the same brand is different. When I was using the Ultimaker I had it completely dialed in using their filament which is stupid expensive (which is why I switched to Matterhackers). Except for the blue. The blue underextruded like crazy causing prints to fail. The solution was raising the temp 10 degrees for the first three layers and five for the rest and then it worked beautifully, but only for the blue.

Yes, it's a coated steel plate, but this is a sample pack that I got for Christmas, and it acts like it's superglued to the build surface.

In the advanced composites industry, we had a number of release agents we used to prep molds, allowing components to pop off easily after forming.

Is there a common release agent used with 3D printing? IIRC I read somewhere that people replace their beds with a glass sheet prepped with hair spray. Maybe a makers forum has some tips about what to use?

Usually, the issue is getting the print to stick, hence the hairspray and gluestick that gets used a lot. It's this one specific color combo that is being difficult.
I could use a new build plate, because this one is beat up. I could probably get a glass bed, which would definitely improve the effects box , but for some things a resin printer would be better.

For the injection molder, vegetable oil is supposed to work well, but that project is begging for attention too.

As someone who printed with a glass bed for years, you don't want a glass bed.

Glass is great because it's "always flat" but the quality of the finish on a glass bed is never as good as it is is from the spring steel beds on a Prusa. Additionally, when you get an over-adhesion problem like the one shown above and you have to use a spatula to get the part off, you'll end up putting micro-chips in the glass. These micro-chips cause heat to be distributed improperly and from that point on you'll get curling of the part where the micro-chip is. The only solution at this point is to replace the glass bed.

I had this on my Ultimaker and it took me months to figure out what the problem was, and the only way I figured it out was by looking at the problem area with a loupe. Going through this taught me to always wait for the part to cool before trying to remove it. Sometimes I even manage to do that.

Thanks for the tip. I'll order a new sheet.

Took the Whipped Llama/TubeSound fuzz over to my buddy's house, along with a silicon fuzzface, and it was initially pretty frustrating. I have to burn some time on the vast number of leds I have, and figure out what the power draw is. Some of them draw too much power to use battery power, and there are no markings, just physical size to go by. Not like I have much on my plate, but an annoyance.

The plastic enclosures are a mixed bag. The pots I bought do not have enough threads to thread on the nut on the sturdy boxes, and the others are too flimsy, even for home use. Had a lot of crackling and intermittent contacts that turned out to be the jacks. If you are using a plastic shell and foil shield, you have to really crank down on those suckered, otherwise frustration rears it's head.

Once that was taken care of, they both sounded great.
