weird layers
so i did some stuff to my vc 400. i switched the heater of the hotend and i made the wire loom a bit bigger to reliefe stres of the cables. othe then that i didnt change anything. i also had to pick the printer up and move it, but im not sure how that wouldve changed anything. well that took quite long to upload . i think its the piano cable it might be to thin.

there is also a high pitched noise comming from the main board that i think wasnt there before
i just checked my e steps so thats not an issue

The uneven and rounded corners looks like too much pressure advance or input shaping. With the changes to the toolhead did you recalibrate input shaper?
ok yeah makes sense. I will look into the pressure advance settings. I don't think I changed anything, but i will recalibrate that + input shaper when im home. thanks
@skrat19 recalibrated input shaper and pressure advance, but that didn't really help also tested belt tension and it looks like this

Huh. That one is rubbing or rattling a part or something. Curious.
Is that a cube ish print? What do the other sides look like? Also if you print the same code again do the patterns appear exactly the same in the same places?
@skrat19 ok will see what i can find, but yeah its cubeish ill testprint a xyz cube to see if it looks simillar
is there a way to determine where exactly something is loose
What does the first layer look like?
conscious-sapphire•10mo ago
I came across this the other day, it will help but there’s no magic to find the loose part. Frequency tester: https://gist.github.com/kmobs/f6def5db272ca5c1b81727482f53bed8

The photographed part is lying on its side, we’re looking at the layers building up from left to right (wiggles throughout the print). I don’t think the first layer is affecting this.
@.quinny it looks perfect no gaps nothing
@skrat19 thanks will do that later.
i tried to match upper and lower belt i got it to this and now i will testprint maybe it helped
@skrat19 so belt tension looksl ike this now. i calibrated input shaper, the lines do look better but not the same as before. so something is still wrong. i hear a weird noise when the printhed moves on the y rails to the back, but i cant figur eout what it could be.
conscious-sapphire•10mo ago
That's a purdy belt graph, great job!
Odd sounds on the rails in a particular location indicates to me misaligned rails (i.e. racking).
yeah, that's what i think too I already got my aligning brackets ready and will see what I can do tomorrow.
The peak around 50Hz is almost missing from the belt graph, there is definitely some problem in y.
i first thought something was loose on the motors but checked them. so my best guess is y rails or extrusion, but I'll check that tomorrow
not sure why i only looked at the y graph now, but there is definitely something wrong lmao
so i adjusted my belt becasue the xy joiners werent both touching the xy idlers so it looks like this now
@skrat19 UT looks like this now realigned y rails. still not perfect and I still have that weird sound that I can't identify
conscious-sapphire•9mo ago
Much better! Still a little wobbly on the face, or am I imagining that? Could be the uneven belt tension.
still a bit wobbly, the problem now is if I adjust the belt tension to be the same then the the left xy joiner wouldn't Touch the left front idler

Ah, your belts are different lengths. The complete way to fix that it take off the belts and lay them out, cut them even, and reinstall. You could also yank the longer belt through the toolhead grabbers but that’d be unreliable.
Either that or the frame isn’t square but money on the belts being different lengths.
@skrat19 I dont know I would put my money on the frame XD, but ill try it out.
@skrat19 new belts sadly didn't fix it. should the belt be in the middle of the pulleys? because mine is on the lower wall of it.
and could it also be a z axis problem?
conscious-sapphire•9mo ago
Yes, ideally they’re in the middle all the way around and not rubbing anywhere.
conscious-sapphire•9mo ago
Can you print one of these test cubes? It might help accentuate the problem so we have an idea of what’s causing this last bit of wobble.

ok then maybe i have to adjust that. will print them.
thanks
@skrat19 I printed both cubes and they have the same wobbly lines
I could use a bit more pressure advance if im not wrong
also two of the 90 corners had the nut like that. I hoped that that was the problem, but it wasnt
@mietzekatzi can you gather any information what could be wrong from the voron cube ?
I have no idea, sorry. Have you tried diferent fan and temperature settings yet?
@mietzekatzi hm ok thanks. fan yes tempereture not yet. im watching a vid right now on how to calibrate a temp tower.
conscious-sapphire•9mo ago
Try disabling both input shaper and pressure advance and print another voron cube. The corners are looking slightly too round and the faces have what appears to be minor ringing. There should be pretty big changes in those things with IS/PA disabled.
Temp is also a good callout as the overhangs look messy but I’m not sure if that will clear up all the artifacting.
@skrat19 printed at 210 and without IS/PA
so I tried superslicer for the first time in a while and it looks like this, even though I have the same settings as in prusaslicer. I'm confused and sorry for apparently wasting your time.
conscious-sapphire•9mo ago
Even with superslicer the logo looks too rounded in the center. Those diagonal bits should have flat faces but they’re round, accentuated without IS/PA. There’s also extruder skipping/under extrusion. When was the last time you calibrated esteps and extrusion multiplier?
I don’t think it’s a slicer issue, the problems persist with SS.
How are you ensuring the right belt tension?
@skrat19 ok, checking my e steps was the first thing I did. extrusion multiplier could be a bit low with 0.96. right now I'm using the belt tension macro to dial it in. how do I actually know if IS is disabled? I put a # infront of it in my printer.cfg, but there is another IS block on the bottom in the section where you cant change it.
well that's not good...

what is that?!
the vid is the back right motor mount and the top motor was mounted there
