My Prusa MK4S' COLD SPOTS were bad, so I fixed them! Now the MK4S has the most even heat @NeedItMakeIt

Fixing the cold spots was easier than I expected, and it should work for the Core One also.

I still have an attachment to the bed slingers even though they are slower and have more mass to move in the Y direction, and the Prusa MK4S is a really nice printer, it performs so well even when I put in the filament from their Arch Nemesis. But after performing a thermal test on the bed, I was surprised to find out that it doesn't have an even heating, not even close and it also has a really low max temp compared to the set value. This wasn't something that I could live with and I think a lot of other people out there would want a fix too. I used the thermal camera and looked at everything to find out why we were losing so much heat in some areas and with a little detective work I think we figured it out. I tried a few fixes, but there ended up being two big ones as you'll see from the video.

$Simple Ways to Make Stronger 3D Prints NUMBER TWO What happens when you do real drop tests on 3d prints? Do they bend, do they break, do they shatter? In this video well find out by testing different materials and designs at several DROP heights. Help support this channel! https://www.patreon.com/Needitmakeit I see a lot of testing videos, some of them are useful to compare materials against each other, but theyre not as useful when you want to apply them to real designs. If we want to protect something, should we use ABS? How about PETG? Or Maybe youre the PC type. I have an okay sense about each of the materials, but I couldnt tell you which material was best to protect expensive equipment, and which material could take continued abuse and not just break after one drop. This video is dedicated to doing realistic dop testing to see if we can get some real answers to those questions so we have a better idea of how to design 3d printed parts, and that we also have a sense about which materials perform the best under which conditions. In the previous video, we tested only PETG, it has a good reputation for being flexible, but it also has this other very strange property of becoming brittle and fracturing at a certain point. In this video were going to see if we can figure out the right mix of flex and strength for that material so we can use it and have the confidence that itll do the job. Which material do you think will perform the best? Check out the video for all of the details, it was a lot of fun, and I learned quite a bit. Lets just say that it isnt all about the size, there is more to it than that. Another way to support this channel indirectly is through my affiliate links (where I receive a small commission).
