Yes I am absolutely sure. I can see it while leveling the bed (using a feeler gauge). If I have the correct distance between nozzle and bed on the edges the nozzle scratches in the middle. And if perfect in the middle the edges are to far away. When I start a test print I can even see the filament not being squished enough to the bed on the sides while perfect in the middle. Warping only occurs to me when printing PETG and even then only slightly and on longer prints.
Thanks!
So you don’t need a probe for your firmware?
Currently I have none attached, but I wouldn’t mind the work of attaching one. But if there’s a way to do mesh leveling without probe that would also be nice.
A friend of mine tried some softer material and managed to get better results printing really really slow. He also had blobs and gaps before that. Also he printed too hot. But I assume you already tried that. Maybe this community here can help? Have you considered making a post here asking for advice?
Not this one, but today I made one for my iPhone 13 Mini. I just measured the hell out of my phone, directly started with the case model and hope it will fit once I print it (probably tonight, as I am currently printing a new fan shroud I designed around a standard Satsana). For easier things I often manage to fit on the first try, but as it gets more complex, there are more prototypes.
Hmm okay… I wanted to order a darker filament anyway. But I will see how long my wife’s holds up. I already ordered a transparent TPU with which I will print a case for my 13 mini (designed a case for it today that has some hexagon design and holes for a Paracord lanyard) and then I will try how long it will get me going. And yes, I am absolutely hyped about the fact that I can now design my very own case specifically how I like it at the moment. Really cool!
For keeping it dry I got myself this one (currently 10% discount):

That always depends on your needs. If I don’t need something right now, I don‘t print it. I had some months i didn’t print at all, because I just had no need for 3D printed parts.
If you want some ideas on what you might need, i suggest going to printables and simply type in TPU.
For me there right now are some small parts I already need to print:
I think that heavily depends on the used printer, parts and filament.
But one tricky thing that comes to mind instantly was e-Steps. I got a metal dual gear Extruder and didn’t realize that the gear was smaller than the original. Because of that I had to change the e-steps in the printers firmware-settings so it knows how much it needs to turn in order to get one mm of filament through. As I didn’t know that I had some crazy underxtrusion and warping problems. Took quite a while to figure out (not only a problem with TPU).
But generally if your partner wants to get into TPU printing, I would get at least a direct drive upgrade. TPU is a flexible material and it’s better to press it in the Hotend as directly as possible. Also print very slow to get better results.
Ah okay, thanks for your information. Will look up on custom firmwares for my printer. Hopefully there is something stable :)
