Uneven surface on prints
Setup: VCore 3.1 300, LGX Lite, Rapido, Orca Slicer, RatOS v 2.0.1
These prints were made with Polymaker CosPLA at 200C
Hi everyone, I'm currently experimenting a bit after noticing my prints have this really annoying uneven surface, + I noticed that when sanding one of my pieces (by hand), some kind of pattern became really evident on it (see pic with the red arrows).

Extrusion Gaps
I have been getting gaps in the same part that appear periodically. At first I thought the gaps might be from a slicer setting for coasting but when I checked the seam location the gaps are too far away for it to be this. I also added some bowden tube to help guide the filament and I thought it might be the friction from this, but everything seems to be moving smoothly. This print was run after I increased the temp from 205 to 210.
Extruder: Bondtech LGX Lite
Amperage: 0.707 (recommeded per RatOS)

IDEX offset but VAOC calibration was OK
Can you help me to understand why I get this X offset during IDEX print if the VAOC calibration was OK?
0,6mm Nozzle with ASA GF
Hello, i upgraded my printer with an 0,6mm nozzle and now my prints looks terrible, with the old 0,4mm nozzle everything looks great. In the photo is an flow test
Weird Artifacts when layers get small & fast
Strange issue I'm seeing with my new IDEX setup on VC4. Print quality could still be improved but is overall pretty decent, until nozzle swaps start occurring and layer times get very short. Things I've tired without any noticable change:
- Adjusting temperature (ABS from 243 to 265)
- Adjusting pressure advance all the way down to 0
- Slowing down MASSIVELY (setting kliiper to 40% speed factor...
3 good layers then no succesful print
Hello,
I have a new VCore 4 Idex and followed the Comissioning Guide, but I can not get a finished print. The first 3 Layers print beautiful. When the Infill pattern starts the Walls curl up and the infill is not printinting right. I tried changing to different filament, flow, checked if the rotation distance of the extruder was of, printed only with 30mm per second, fan speed from 0 to 100%, changed the Infill type and speed. I tried everything I can think of.
I started with the standard prusa slicer Profile without any success and changed values but it did not get better. The first 3 layers are perfect and print smooth. After those 3 layers the walls curl up, get this weird pattern and the infill is not printing properly....
IDEX prints not clean
So I'm trying to get down IDEX prints and started off with a dual color benchy. In Copy/Mirror mode both benchys look fine. The X/Y offsets seem to be spot on as well.
What I've noticed so far: The zhop on a tool change always causes stringing which is why I've played around with the zhop height and retraction length. But nothing I've tried works so far....
Vcore V4 400 IDEX + eSun ABS+ clogging
Hello,
i am trying to print a part with a lot of small 6 hexagons and i am not able to get past the first layer because of clogging.
First Layer temp. 235°
Other Layers: 250°...
Odd artifacts on PETG prints on VCore4 IDEX
I don't know what to do at this point. The gaps appear to be under extrusion but at the same time I have the feeling its over extruding. This happens on both tool heads to I don't think its a physical issue.
Z shift - gap on layers after M600 filament color change (VC4 500)
Hello, I am having this big issue where after a filament change (M600), the print presents a pretty big gap at the layer of change. Could it be a problem with the Z motors or software related ? How could I debug/fix it ? It's really ruining all my prints, both ABS and PLA.
It always worked well and made dozens of prints with the swap and following layer fusing perfectly.
Could be the Z steppers or some mechanical issue on Z ? Unfortunately a few times I printed full height objects and in the following prints the start macros made the bed go down beyond the lower rods limits and I heard the motors cranking badly :/ . Something happened in that moment maybe ? I really need to fix this, any help or inputs greatly appreciated!...
2nd and 3rd layers are not working .
I have just got my v4 500 idex Hybrid ready and doing the skew print. And the 2nd onwards layers are not sticking down and being run over by the nozzle. What can I do. .6 hotend and using the standard ratrig quality profile on pursa slicer. First layer is set and comes out great.
bad rounding
Since I have updated my vcore4 400 to idex, I have this problem with curves, they are never smooth, any idea ?
persistent top layer smush
i’m pretty happy with my print quality, but I can’t seem to get rid of top layer smush in close quarters.
first two pics are from https://ellis3dp.com/Print-Tuning-Guide/articles/extrusion_multiplier.html
following pics are my prints. is this an EM problem? a top layer extrusion width issue?...
How to find right Flow
Hello,
Normally I have no problems with this part of calibration. (So on my Prusas and Bambulabs)
But with the Ratrig v4 | can't get the right value. I already printed the orca flow test and there I got the value of 0.92 but the parts are a little bit underextrusioned like 1-2%.
So I printed like Ellis guide said 30x30x3mm cubes with 25% infill and 10 top layers and there I would take the 0.95 flow one but then the parts are a little bit overextended on some points (the pictures are all on 0.95 flow) and the other part have 6 top layers...
Bad top surface quality
I have recently upgraded my hotend to a Goliath & using a CPAP fan now too.
I have noticed that my top surface quality is very bad. Any suggestions to fix this? Is it too hot, too much cooling too wet???
It appears to only be the top layer or the 1st layer above infill.
The photo is with eSun grey PLA...
