Nozzle lifting itself while printing first layer
Not sure what to make of this, but during printing, the nozzle keeps lifting itself higher over time. In the pic you can clearly see a nice first layer to the right, with slowly a gap forming towards the left. The gap disappears when lowering the z-offset by -0.05 mid print. I have to continuously lower the z-offset during the first couple of layers, after which it seems to stabilize.
So this is what I have tried so far:
- 1 -2hour bed heat soak
- 10 min nozzle heat soak
- Stable chamber temp @45c...
IDEX blobs
Im trying to dial in the IDEX and have some troubles..
I get these blobs on the sides of my test print, when switching T0/T1 - is there a way to tune this further?
Thanks a lot for any help! 🙏...
Pessure Advance
T
o tune Pressure Advance, I printed a square tower with 0.3 mm layer height and a 0.6 mm nozzle in PLA + . The best results were with:
pressure_advance: 0.160500
pressure_advance_smooth_time: 0.040000 However, I’m still getting ripples or waves at the beginning of each straight line in all axes....

Corner Pattern with 0.8mm nozzle
Hello,
I switched to a 0.8m nozzle and suddenly have these strange corner patterns appearing.
Temp: 285°C, PET-CF dried, 0.8mm Line width, 0.2mm Line height.

Rough top layer
Walls look great but any top layer amd start of a layer will come out rough. Sharp edge also not perfect after lots of PA tuning. Any ideas?
SO MUCH GHOSTING
New VC4 hybrid, XY Y1Y2 motors are LDO 2804HT running on 24V 1.6A getting this weired ghosting that I cannot figure out why.
The belts are not too tight and not too loose(I have a good record of building printers) and it happens on both X and Y axis so this is not from the Hybrid Y.
I am using SnakeOILXY klipper fork using the corexy_extended kinimatics but it still happends with normal klipper fork.
I made the configiration by my own, but I don't see any problem with it.
when running input shaper using the beacon acceleromater I am getting around 18K on both axis using mzv....
Inconsistent layer lines - fixed
Sharing this for anyone that may run into this issue.
I had inconsistent layer lines, and every uneven layers. Primarily on the front of my prints. I was also experiencing a lot of jams and issues with the extruder wearing through the filament to the point where it couldn’t push or pull the filament.
Fix: I routed the filament through the back panel, reducing the turns in the ptfe tube. ...
Fuzzy lines / underextrusion?
Idk what happening here. I try everything, exchange nozzle, higher temps, lower temps, flow calibration, etc. First layer is good, but second the printer go fasterbit starts doing this.
RatRig Core 500 + beta profiles for prusaslicer.
Thx for help....
Tons of woodgrain, how can this be fixed?
This is one of the more severe examples [black pla+], but this is happening in as good as to every print I do regardless of the filament.
I've done input shaper and all thag already.....
Strange artefacts on VFA tower
Hi! Just assembled my 500 hybrid v core 4, doing fine tuning setup right now. Input shaper graphs show max accel on Y 5000 accel. In slicer outer layer is 4500, normal printing 10k, first layer 500 (got values from bambulab X1C). Max volumetric tested only to 34 cubic mm, and extruded that perfectly fine (CHT hardened nozzle). Speed for outer walls lowered to 140mm/s.
My prints still look like 💩. While doing the vfa tower, what material i didn’t use, I get same artefacts. Maybe someone has an idea what could be wrong?
(Sorry for side way pictures)...
Temps T0 and T1 not right during IDEX print
So I'm printing some simple covers for a project where I have embedded text in the first layer. This is done with T0.
I see the following problems:
During a layer change Orca sets T0 back to 260 so it heats up again and stays here during the whole print (not ideal)...
Unclean extusion in inner wall/internal solid infill
The inner wall of this model is always getting unclean at a certain height, which can be seen on the to surface a few layers later. I have a vcore4 idex 400mm with recommended 5.2k accel and .5 nozzle. I use Orca slicer and turned down the speed/accel and oriented them to the official profiles from RR in prusa slicer (also the PETG settings). I also tried prusa slicer, but had the same error. The flow is well calibrated and i also tuned PA. The material is PETG. I printed a small test piece, whi...
Inconsistent walls Vcore 4 500
Hey I am having issues with inconstant walls. When printing let's say square objects the wall dimension changes changes if let's say a hole is present, or if another feature is present.
I think the image is better at explaining what I mean....
