First Layer problems
Hey, I have a Vcore 3.1 500 and even after a long time of fails you might can help me.
I never get the first layer right as the printer seems to "over-calculate" the Z-offset when doing the first layer, normally it should flaten out the humps and bumps in the bed but in the areas where bumps are it drives the nozzle too high leading to non-sticking areas and on the other end on humps it drives the nozzle into the bed leading to stop the flow completely due to closing the nozzle by pressure of the bed. in the middle where the z-ofset is set its perfect.
I even ordered a beacon to probe it even better but this didn't help at all, also setting up the complete printer from the ground didn't chance it.

Stringing Isue
Hello. I use "clone (Non original)mosquito magnum hotend" on my v core 3.1 printer. I use cura as a slicer. When I set the retraction setting to 5mm, there is no threading or speciation, but since I use a direct-drive extruder, the filament bubbles and constantly clogs at the 5mm retraction setting. That's why I reduced the retraction distance to 2mm, but as you can see in the picture, it leaves too much thread. When you make it 2mm less, it becomes more. I use esun pla+. The printer operates at...
Sagging ASA on overhangs
I'm trying to print a new logo head for some part updates and I seem to be getting a lot of sagging issues with my ASA on the overhangs.
Using my qidi xmax 3 at 250c with chamber at 60, no cooling save for 20% on overhangs and printing at 40mm/s on outer wall, 60 inner. Tried supports but no luck....
overextrusion in some areas
I have recently tried many things to combat ringing and bulging of corners on a calibration cube.
BĹ«t for this file I have another issue. One corner is rounded, the other kinda straight but with a miniscule bulge that translates in ringing like effect.
So Y->X movement does that. X -> Y movement looks great.
PA tuned, shaper tuned. Tried slow speeds, fast speeds. Slow accel and high accel. High both do better in terms of overall quality.
Same on calibration cubes....
Filament is sticking to the internal Teflon tube of the Hotend
Hello all, I have a Phaetus Rapido UHF Hotend and I'm calibrating the first layer, but although I can print the first layer without any problems, I can't make a second print because the filament gets stuck to the internal Teflon tube of the hotend. This is the second time I have had to disassemble it to unclog. I'm using the temperatures recommended by the supplier, and the filament is Elegoo PLA+. Could this be due to the filament or the Teflon tube? I really need some help, thanks.
Solution:
Thank you very much for your attention. I've solved the issue; it turns out the Hotend wasn't being cooled enough by the fan.
underextrusion-like artifacts at small layer heights
vCore 3.1
nearly latest RatOS
Rapido UHF (Volcano nozzle)
I use variable layer height with OrcaSlicer 2, at the small layer heights (0.1mm) there is something like underextrusion or a partial clog (looks like it, but is not that). In the middle, where the layers are higher (0.2mm) the print looks fine....
Holes at Z-Seam with large nozzle
V-Core 3 500 with Orbiter 2.0, Rapido UHF and a Bondtech CHT 1.2mm nozzle.
RatOS 2.0.2.
PrusaSlicer 2.7.4
Printing with any filament results in pretty severe underextrusion at Z-seam.
Layer Heights between 0.2 and 0.6, layer widths between 1.2 and 1.6 mm....
Solution:
FWIW: I solved it using a „Deretraction extra length” setting of 0.4mm.
flow or z move issues
I'm having troubles getting a good print since a week. I recalibrated the flow, the z offset and the temp.
But I'm having those aweful top layer issues.
Top layer is rough and the sides are showing too much inconsistency.

what should I do… polymaker pla warping… noob here
I am using polymaker pla+
Prusaslic3r setting:
Nozzle: 1st layer 205, other layer 195
Bed: very much default: 1st layer: 68, other layer: 68
I have No fan on at all....
Weird Artifacts / ripples due to Volumetric Flow Limit
So I just got these artifacts during a print on my VC 300.
has anyone ever seen something like this?
It appears on all arcs (inside and outside) except for the innermost ring. Also on the straight sections between the rings, but not on the purely straight sections that are above.
...
Rough artifacts on surface
I seem to have developed some rough wavy scarring on the external perimeters of my prints.
I am sure something is loose or something, as this is a new occurrence after updating/rebuilding my toolhead to RR beta 2.
I had found some loose grub screws on my pulley gears, I tightened those, and that fixed some other issues....
Solution:
I mentioned how I got a brand new rapido hot end....Welllllll.....they come default with a 0.6mm nozzle installed.....
Ringing/Artifacts Only in One Direction?
I've been having print issues where after calibrating input shaper, there is prominent ringing on only one side of a print. This ringing seems to only happen when the y axis moves in the positive direction, so it's not specific to the side but the gcode motion positive y motions.
I've had this problem since I built this vcore 3 500mm. I've swapped all the idlers, flipped every linear rail, swapped the x axis linear rail to mgn 9. Swapped the x extrusion, swapped the belts in the complete 3.1 upgrade. I've swapped the motors, changed the joiners 3 times from the 3.0, aluminum 3.0, 3.1, to the aluminum 3.1 from funssor. I think I've swapped every single possible component of the motion system, I've disassembled the frame so many times to realign, and there's still the same issue on every single print. I've swapped out the cable chain for a chainflex cable, and now I have a canbus system.
Resonances have looked perfect since I made the printer, and so do belt tensions. ...
Anyone have an idea why this extrusion multiplier test looks so bad/weird overall?
All of the squares have ridges on the top that i can feel, and they all have odd "patterns"? on the top as well as i heard it scrape a decent bit, i'm setting up the printer and doing the test to get it dialed in, and while doing the heat tower test, it kept knocking it loose, so i thought it was over-extruding so i decided to do this test instead, but am now at a dead end. anyone have an idea on how to proceed? my printer is a v-core 3.1 kit and i am using super-slicer
Terrible ABS Bridges on Orca Slicer
You can see the difference between orca and prusa. My settings are near the defaults, and I have increased and decreased flow, fan, temp, etc. Tried my best to have the same settings.
