I can't imagine how input shaping works if resonances change with belt tension π€ We are saying in this case: Pointing βοΈ with a finger in the sky
You can also try different speeds of the external perimeters. At some point, it can be less noticeable. Or become worse π Don't be afraid of experiments, it's your experience πͺ
That looks more like VFA, not ghosting or ringing π
Yeah, looks almost like mine π Did you tune your flow rate, calibrated it?
Oh, sorry, I forgot to ask your permission π±
If they are not removable... Do you have compressed air and some brushes?
P.S. I have the same setup as your π
Never heard about Prusa printers, but once happened to me that my print melted down on my Ender's 3 build plate. This happened right in front of me in the office. Later I saw also how very expensive printers burn (20k+ Euro). So it's for you to decide about safety measures.
Or change orientation, or instead of radius, put a chamfer on the bottom. More cooling and slowing down might help, but in any case you'll have some troubles there
Ahahah well, even in this orientation it will work because of the compression of the layers, but I'm a kinda perfectionist πππ
No, bro, not good :( I made a mistake with layers orientation + there's no threads+ PEI sheet isn't so good π But it took me 2 minutes to render and go to sleep ππ
I did this for my laptop π€ Helps a lot πͺ
I'm still waiting for them from AliExpress, so I used M3 Nuts. I can add the version with inserts by request π€
Oh shit, I just noticed, that the lines are in the wrong direction π±π€¬ I use KeyShot π€
There are two ways - to use Autotune or to use Chopper Resonance Tuner. In the first one, you insert the parameters of motors from the datasheet, cross π€ the fingers and hope it will work as it should.
In the second case, it will do a test of every parameter of your drivers and build graphics. Then you'll need to choose the parameters that guarantee the lowest power consumption and noise for every axis. But attention - every test takes 2-4 hours per each axis. This test DOES NOT replace Input Shaping.
I used it for 1) Input shaping to find weird resonance frequencies. 2) To tune the TMC driver's parameters to run even more quietly and find resonance speeds to avoid them during printing.
Yeah, I finished measurements late night yesterday and didn't have time to take photos
I have only 19 meters πππππππ
I finally made it
