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)...
Temps T0 and T1 not right during IDEX print
So I'm printing some simple covers for a project where I have embedded text in the first layer. This is done with T0.
I see the following problems:
During a layer change Orca sets T0 back to 260 so it heats up again and stays here during the whole print (not ideal)...
Unclean extusion in inner wall/internal solid infill
The inner wall of this model is always getting unclean at a certain height, which can be seen on the to surface a few layers later. I have a vcore4 idex 400mm with recommended 5.2k accel and .5 nozzle. I use Orca slicer and turned down the speed/accel and oriented them to the official profiles from RR in prusa slicer (also the PETG settings). I also tried prusa slicer, but had the same error. The flow is well calibrated and i also tuned PA. The material is PETG. I printed a small test piece, whi...
Inconsistent walls Vcore 4 500
Hey I am having issues with inconstant walls. When printing let's say square objects the wall dimension changes changes if let's say a hole is present, or if another feature is present.
I think the image is better at explaining what I mean....
Wavey first layer and wierd layer artifacts
Hi, i have been trying to callibrate the my v-core 4 500 for the pas week or so, and this is as good i as i can get on my own, so now im seeking help to understan what i need to do to fix these problems.
I have tried several diffrent things o for the first layer problem
BEACON_RATOS_CALIBRATE
BEACON_FINAL_CALIBRATION...
Larger layer time causes visible line on external perimeter
I'm printing what is essentially a rectangular box, with walls that are a lot thinner than the box is wide (~7 mm wall thickness, box is about 70 mm at its widest).
I would like the inside of the box to be nice and smooth so I perform ironing on the inside bottom of the box. This causes the ironing layer to take significantly longer than the surrounding layers (20 minutes vs. a few seconds), and the result seems to be a very visible line on the outer perimeter of the box, where it consistently overextrudes in some places. Turning off the ironing seems to stop the issue.
I know this is a relatively common issue, but I've tried many things and nothing seems to work to get rid of that line. Here are some relevant print settings:...
Odd repeating artifact 8mm height
Does anyone have an idea what this could be? It is not all the way around but near the "seam" of the circle. Sliced in Prusia Slicer
First Layer solid infill starts faulty...
Hello all,
I am facing an issue with printing PETG since today. I think I did not change anything to the settings since last time I printed PETG which is kind of odd.
I tried already less retract, higher Temps. Flow and PA are calibrated. So I dont understand this behaviour.
Does someone have any tip?...
Is this extreme resonance?
I am not sure what happened with this print. I used Ratrig generic print settings. 0.2layer height, 0.6mm walls, 200mm/s 5K accel. sliced in OrcaSlicer.
I am running a VC 3.1-500 with BRS AWD upgrade.
The print was orientated approximately 30° off vertical so there should have been no overhang issues....
Infill intersections not connecting
Ignore the slight underextrusion on the below solid infill layers, my main question is why do the infill intersections not connect? These eventually creep up and scrape against the nozzle and get really crunchy. It seems like a retraction problem to me but am not finding the right knob to turn. Adjusting retract length, retract speed, pressure advance, smooth time did not appear to make a difference
Weird artifacts at corner
Unsure what is causing the weird lines at the corners of my prints but this was all done in pla with 60% cooling enclosed hybrid v-core 4 500 with the default orca settings minus fan speed. Don’t worry about top layer print was cancelled before completion
Solution:
For me bumping temps by +5 - 7c fixed that
Lines Not straight
Hello it seams that lines where th y Axis is involed seem to be wobbly, in my idex VC4 500.
This also occures when printing very slow.
Does anybody know why?
Please help l'm out ideas....
Lots of VFAs and layer shifts
Had this start today, I am getting loads of horrible layer shifts and VFAs, this came seemingly out of nowhere...
Tons of stringing out of nowhere
The picture below is retraction testing starting with 0 at the bottom to 5 at the top of the large. I have a direct drive and the gears seem to be fine. I did a temp tower and 200 seemed the best. No change in reaction speed or amount or temp seems to make it better. Im out of ideas. This also happens with both new and old filiment and started recently. Oh I also changed the nozzle to a new one with no change. Any ideas?
