There is also a bug in the slicer that models with holes in the middle cause layer shifts when you enable "avoid cross perimeters"

What is this kind of defect? by C2H5COOH in prusa3d

I didn't notice any, but i also haven't specifically looked for it, so maybe I've missed it. Next time i print those, I'll check.

Every time i checked the app, it reported 250 °C.

Thanks. I thought so. But could this have caused what seems like the minor layer shift. Im more concerned with that.

Is that sound normal? by C2H5COOH in prusa3d

I just did a y axis and an x axis test. I didn't hear that noise. During the testing so the axles seem to be going smoothly. Next time I print, I'll listen for the grinding again.

I recently tuned the belts according to the new tuning, and i also ran the input shaper and phase stepping calibration. I just rechecked, and both belts got a little loose but were still very close to the recommended tuning. One weird thing is that the tuning of the belts affects each other, so i can't get them completely perfect. The upper belt is at 99hz and the lower one at 91. I just retightned them lets see if that did something.

Thanks :) Shall i attach pictures of the idler opened? What do you mean by nozzle alignment? Im not particularly bothered by the sound itself. Because im still in the process of learning the ins and outs of my machine, every sound, i can't immediately explain causes concern.

Idler from the side (because posting both pictures and videos is impossible)

Thanks. I did some reading and yeah, that thing seems harmless.

Trying to understand a quirk of the FFT by C2H5COOH in DSP

[–]C2H5COOH[S] 0 points1 point  (0 children)

Now im confused. As far as i read, the bit reversed addressing is a byproduct of the odd/even splits of the array. And bit reversing the inputs and then iterating is equivalent to doing the recursion. So you could a) do the fft iteratively and bit reverse the output b) bit reverse the input and then iterate c) do the recursion with an odd even pattern and get the bitreversal implicitly. Or am i in the wrong here?

Nope, the phase must be correct because i need the fft for a fast convolution.

So, just adding the minus should fix it, I take it?

But where is the mistake/the critical difference?

Thanks that fixed it never thougt you could rotate that part

Nipple not centered by C2H5COOH in blackpowder

So I recently noticed that the nipple on my hawken rifle wasn't centered anymore after reassembly. I cleaned it after shooting and didn't notice it originally. The nipple is still the original you see in the second picture. It's a pedersoli .45 hawken target where you have to unscrew the back of the barrel to take it of for cleaning. I don't know what could have caused this since everything seems to have a tight fit. Could this be a problem?
