Uneven texture 3.1.
I have been battling this for some time now. The prints come out uneven, wavy and just overall shit.
The resonance is terrible as well.
What i did:
I have changed the belts to try and fix this, have the back metal motor plates, to access everything....
Print slows down at smallest imperfection of file (prusaSlicer)
Hello,
so I've currently got a slicing problem. My sliced parts (exported as step-file but it has gotten some tiny imperfections for some reason during the export) have a lot of speed deviations which you can see on my figure. These results are also visible on printed parts.
I also tested it with a simple STL-file, but its worst in that case. Can anyone help me please? Thanx in advance

Edge roughness on the first layer
Was it too high bed or nozzle temperature? Other?
#3do-🇪🇺 ASA black printed with V-Core 4 IDEX.
The suggested temperatures are:
- Nozzle: 220-250°C
- Heatbed: 100-110°C...
Strange infill separation problem after pretty good first layer
Seeing this issue trying to print a v-chonk base. First layer isn’t flawless but looks pretty ok at least to me. Second layer even starts ok…but then at some point midway through that second layer the lines just start lifting up and separating from each other.
Second time this has happened. First time it happened I figured I’d up my extrusion multiplier to make sure enough plastic was going down. I also went ahead and dehydrated the filament for about 7 hours at 60. Unfortunately those changes didn’t do a thing. VC3.1, Polymaker ABS, 100 on the bed and 260 on the nozzle. 1.0 extrusion multiplier (was 0.92 on my first attempt). I’m struggling to understand what sort of issue would cause this kind of behavior. Can anyone who’s seen behavior like this before ELI5 a plausible explanation of what might be happening here?...

Vcore 3.1 idex overhangs and support material
I'm using pla and polysupport pla on overhangs. Wondering if anyone can help me with my settings to improve this
inconsistent layer stacking
v-minion, dual z, oldham decoupler, orbiter 2, rapido 2.
i thought it might be PID related, but that doesnt seem to be the case. I feel it might have to do with some Z play in the oldham decoupler icw z hops. the upper part is printed in vasemode and is mostly perfect. any ideas?...
Commissioning - Ripples in first layer
Hello, I am at the Z offset part of the Commisioning guide. I'm using PolymakerABS for the testing here. Will PA and EM fix the ripples here or should I be looking elsewhere? Based off my reading here I think my belts and mesh are okay?
Any help would be appreciated!...
I have fought this for over 5 months now I have consistent voids in my extrusion
I have calibrated
temperature
flow
pressure advance
max volumetric flow. ...
cleaner bridging and overhangs
Im in the process of printing the v-minion 1.1 parts and looking to clean up my bridging/over hangs in the logos (see attached example and default orca speed settings. This is printed in ASA at 260/100. You can see a defined ripple in the middle, looking at the bridging/overhang speeds in orca slicer makes me think that they are not correct. Thoughts?
Pressure advance issue? Other?
I tried to tune the Amazon Basics PETG. After some tests on V-Core 4 the print quality has deteriorated. The main recent change was SET_PRESSURE_ADVANCE ADVANCE=0.075 after a 10cm tower in Prusa Slicer filament Start G-Code. My slicer filament preset on the right an the Generic PETG on the left.
Do you have suggestions to fix it?...
Inconsistent Flow on each print/ day
Hello,
This is ABS and I have little gaps in the massive infill but also a little bit overflow in the top layer. I print with 15mm/s max flow and have a speed of 200mm/s on the infill and 100mm/s on top layer.
I am thankful for every idea or Tipp....
Vertical ripples/horizontal lines/Z-banding
Hi everyone. I'm currently reprinting some parts of my VC4 using eSUN PA6-CF with a SiC nozzle.
I have some strange horizontal lines (vertical ripples). See picture. The peak distance is around 1mm. The lines are going around the complete part, so it's not an X or Y layer shift.
For me it looks like the flow for the outer perimeter is changing with height. (which cannot be IMHO)...
PETG Problems
So I'm having 2 issues while printing PETG on my VCore 3 500. One issue is bridging, even when supported. Small bridging isn't coming out terrible but not great either. But in further layers it ends up being good enough. In the second picture you can see top layers of the same print are coming out weird. I dont even know how to describe that. I'm running at 235 and will gladly send any additional info.
Layers not sticking past layer 3
At my wits end, 245c on hardened steel nozzle printing PET-G, finally fought my way through getting the first layer successful now I'm getting this
Any advice is welcome...
Wobbling / moved walls?
Hey all! I printed the first big and height print tonight. I wonder about the moved layers around the windows.
Between the windows the wall is just thicker and this line above is just moved to the outside by around 0.1mm
Overextrusion? To fast?...
The first layer worsens during printing
Do you have suggestions to get if fixed?
I’ve followed the commissioning guide and printed a, heat tower.
I’m printing with Amazon PETG....
Solution:
I’ve repeated the beacon calibration after heating the bed for an hour at 85ºC and now it appears to be solved
uneven walls.
Hi all. Does anyone had same problem and solved it? Walls on my print are not very even, but I don't see any repeatability so I assume it's not PID (I did that) or Z axis. Could this be because of too loose belts? If yes, how much do you tighten your vcore 4 500 belts?
