Benchy Bow Curling
I'm attempting to increase my print speed with PLA+ on my Vcore 3.1 (Eva 3.0, 4048 fan with mosquito hotend and orbiter v2.5). Previously I've been able to print a benchy at about 34 min without any artifacts but I'm trying to achieve a 20 min benchy. I'm having issues with the bow curling up during printing. I'm also running into a problem with orca slicer limiting my flow rate lower than what I've set it to (changing to 0.2mm layer height fixes this).
Things I've tried: reduce temp from 220 down to 215,210,205. Enablling and disabling overhang slow down at curled perimeters.
- 2 perimeters, 10% infill, 3 bottom and top layers. 0.25mm layer height, 0.4mm width....
Regularly spaced lines on pieces (Z banding?)
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, showing these equally spaced lines (that seem to have 4mm spacing, so it should be Z wobble?)

Gaps on top layers when bridging
Hi,
I have been running my new v-core 4 hybrid for a few prints now and tried a print with many flat top surfaces today. There are parts where it needs to bridge. On those layers there are clear gaps where the filament simply did not stick leading to a very ugly layer.
Filament is ABS

Extrusion/temp issues at higher layers
Running a Vcore 3.1 with a Rapido 2 uhf and an Orbiter V2. Bought the kit in december '23. Have noticed some small issues regarding extrusion when doing longer/higher prints, but this one has gone worse than the others.
Started out at 185C hotend 60C bed, ran for a day, started underextruding, upped temp to 195, lowered speed to 100 (started at 200, 170, 150, 120), went well for a bit, until this morning when it started underextruding again, upped the temps again but the extruder just ended up skipping. I was thinking about a partial clog, but looking back I suspect something else since I've had issues with high prints since the beginning
I had underextrusion issues on my last higher prints aswell, but never had any issues with temp towers and such. Could it be that the bed temperature helps the extruder for a bit which hides the issues at low heights?...
Prints look bad with new Toolhead
Hey guys,
I changed my EVA Toolhead for a new Ratrig Toolhead with a Phaetus Rapido Plus 2.0 UHF Hotend and a LDO Orbiter Extruder V2.5. But since the new build I can't get any good print results out of it.
Does anybody have an idea what I could do to improve the Quality?
Thanks in Advance...
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)
Printer: RR500 3.1...
Solution:
that is the correct setting indeed, that value depending on your filament, hotend and nozzle size/style
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°...
Solution:
After many "first Layer" Testprints i was able to find my own settings.
Anyway, thnaks to everyone who read through my description!...
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.
