Abrupt Z offset when printing in different C direction
I am printing a different material than plastic, but I think the problem can be applied generally.
As you can see in the image, the print immediately stops after the curve when printing in opposite x direction. The sample lies in the corner at the zero point of a ratrig core 3.1
Do you know what could be the issue? I was thinking if it was a bed mesh issue than the print would gradually stop, and not immediately after the curve....
Layershifting
Thanks a lot again everyone for helping out, i think i might be close to getting it sorted now, after fixing the calibrations and offsets, pa and flow cal, this is what it did overnight, i did print some layers at the bottom properly, but then did this zigzag. The central layers also did not get stuck to the support underneath them.
What am i doing that is causing this issues....
Z-Offset wanders a bit a the beginning of each print
Hey!
I am currently having the problem, that my V-Core 4s prints start off with a bit too high of a z offset. After a while, Id say about 2 or 3 minutes, the offset gets better, until after about 5 minutes, its perfect.
This problem does not come down to a warped print bed, as, even when the print head returns to the exact same position later, the offset that was of at the start, is now perfect. (See picture)

First layer test is good, skew test fails: nozzle hits after a couple of layers
The nozzle hits the print or i am assuming its extruding more. I have changed the speeds as well as the multiplier to 0.62, it did print better for some layers but did the same thing again.
I have atached pictures of many of my skew test and a model i tried printing.
thanks for help and advices...
V-Core 4 hybrid back benchy sign
Hey i recently build v-core 4 hybrid and printer few parts with awesome results. Made benchy and it came out almost perfect but not the sign "stern" on the back. Any tips? Nozzle 0.4. Easy pet-g in black matte from fiberlogy. 260C and bed 90C. Speed 200mm/s accel 12k. Part cooling fan in default ratrig settings.
Horrible print quality
Hi there - I can’t seem to get my printer to print right - here is the latest cube. I’ve not seen anything like this so i don’t know where to start.
Solution:
Was using .6 nozzle instead of .4
X axis drift on v-minion
This is my printers version of a cube. I've tried switching slicer, it did not help. I've oiled the rails as it was having more wiggles and I thought it might had been that. I had no issues printing stuff for Christmas. It's been unused for a few weeks, so I updated it when I started it. And then these issue appeared
Mainsail thinks it's printing a perfect cube, it certainly is not a perfect cube. Does anyone have a solution or do I have to reflash it again?...
Solution:
Solution:
Retightened the thing in the photo, tuned the x axis belt, some good old sewingmachine oil(on the rail and carriage)...
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....
