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?...
Holes in massive Infill but little overflow on top layer
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?
VCore4 500 hybrid 2nd layer major over extrusion
I've been trying for a few days to print a bumbag and now have a solved my first layer issues enough to try the whole print. Shortly after the 2nd layer began, I'm getting this crazy over extrusion. A few blobs I can deal with but this is unusable. I can't decide if this is a Z issue, slicing, or flow calibration. I also don't know how to confirm if I have one of the faulty earlier release rapidos but that crossed my mind. Any suggestions would be appreciated.
Printing in PLA with the rapido 2 uhf .6 nozzle for now. Dried it yesterday for 5 hours in sunlu s4. (Petg later if I like my layout)
PID tuned the nozzle, did cold and hot meshes. Print was started after ~30 min preheat at 70c...
Weird ripple effect on otherwise flawless PETG-CF print
Hi guys, I seem to have some oddities with my CF PETG. There is a weird rippling effect at certain parts of the print I cant really pin down. Any suggestions onto what might cause it will be welcome!

Ghosting after the seam
I'm getting some artifacts after the seam and only there so I'm pretty sure it's not the tension in the belts
Help with my stringing and layers
Hey guys I’m currently having issues with string useing petg I’m running a mechanically stock Neptune 3Pro running klipper and I use orca slicer filament I’m using is elegoo rapid PETG with .5 Nozzle @ 240c and bed temp at 85c I’ve looked at videos on YouTube about how to possibly fix it but when I adjust the values I don’t really see much of a change or I’m just not understanding how to fix this problem could anyone direct me to a good video to better break down the values that need to be chang...
External Perimeter Resonance Issues - stretching/scratching marks on outer shell
I'm trying to figure out my best quality & speed settings for external perimeters to make the outer shell of the print.
I've tuned extrusion, flow rate, temperature, cooling, etc. and am getting very good results as far as the tops and bottoms of things go, so now I'm onto Resonance, Pressure Advance, etc.
I'm following the https://www.klipper3d.org/Resonance_Compensation.html guide, so Input Shaper and PA are off.
Attached is my latest tuning tower, and a recent best surface finish print...
Fillament change
hello there i was wondering what i can do to reduce or fix this, print looks awesome but the speed changed here and you can see the fillament has an other kind of colour change from this speed
