beacon calibration
Can't seem to get good first layer lines. I've ran the beacon calibration multiple times. I've retightened the belts and made sure both sides of the gantry touch the end stops at the same time.
I also noticed that Beacon scan compensation is disabled.
Could that be my issue?...
Overhang problem
Hello,
i'm out of ideas what's the problem.On overhangs the outer line wraps up and for this the outer radius looks terrible..The rest looks good to me.Don't know how I can solve this problem..V-Croe 3.1 400 enclosed,ASA 250°C ,Bed 115°C ,Chamber 55°C.20% part cooling fan starts on 3rd layer fan is the Sanyo Denki 4028 .Flow multiplier 0.9. Slicer is orca.. Outer perimeter speed 60mm/s. Have somebody an idea, please.....
Artifacts? Too much jerk?
Unsure exactly problem. Print quality is not great. Flow, pressure advance first layers all good. Height shows wavey layers and artifacts. See picture. Any suggestions?
Poor Top Layer
I have a VCore 4 500mm Idex. I finally got decent first layers, but am having issues with the top. The bottom left corner of the larger print did lift from the bed a little. However, that does not explain what is happening in the middle. This is PETG filament.
IDEX retraction and flowrate?
I've been trying to tune my machine for a while now, it's now printing pretty good on each toolhead black petg-cf and regular petg in pink, both park benchys look pretty good to me. 0.16mm, 4 Walls, 4 bottom/top layer 5% infill -> 35min
I don't understand why the idex print looks so bad though! Z offset as well as XY offset look good to me and seem to work great,
but it seems that retracion and flowrate are terrible?

First Layer progessively gets too close VC4 500
This just recently started, never seemed to be an issue until the past week or so. The nozzle slowly creeps to close to the bed as it goes, to the pont that the nozzle is scraping the bed fully and depositing nothing.
I have tried to re-slice things, used an older file, cleaned the nozzle, nothing seems to help. I haven't messed with any settings or hardware from previous when it was working fine. New heightmap and calibration did not help either....
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)...
