First layers with artifacts on new V-Core 500
Hi,
I just got my V-Core 500 to print (kind of). However I'm struggling to get a good first layer (on one side it's too far off and on one sids it's too close). Also I'm getting extreme artifacts on the 2nd and 3rd layer (see picture).
My setup:
V-Core 500
0.6mm nozzle
0.3mm layers
Filamentum ASA
I'm completely lost right now and ready to bring the V-Core to the dump. Is my build just bad or can this be tuned?

Looks over extruded in general but I think I see what you mean... These are your first prints? How does your mesh look? Did you do any test prints?
With an induction bed sensor it is very common to have to adjust the Z height depending on whether the bed is smooth or rough. If the bed is set for a smooth bed, it will usually need to be set closer for the rough side. The plastic needs to get into the nock and crannies of the bed in order to stick properly. It is hard to tell everything from one picture, but the initial impression is that the first layer may be too close. It may also be overextruding some. Each filament will usually need to be adjust for proper extrusion for the nozzle and temperature you want to print at. Your bed leveling looks good and uniform. Honestly you are not far off. With some tweaking you will soon be there.

Thank you for your help! Yes these were my first prints. I thought these were good prints to get my Z-offset right as it has a lot of "surface" to tune for. The strange thing is, I use the same filament in my Prusa with a extrusion multiplier of 1 without any issues and I was already printing this at 0.85 on my V-Core.
I printed some test cubes, did extruder calibration (no changes needed) and extrusion multipler calibration (also no changes needed) so I'm a bit stuck now...

Extrusion multiplier seems to be spot-on

But also strange artifacts on top-layer of test-cube

So, did some testing:
Printing at 100mm/s: no issues
Printing at 350mm/s: drama
Not a big surprise that your extrusuon mult is different... Filament may be the same but you have a different extruder, hot end, nozzle, etc... I've also found that my rr needs lower extrusion mult than my other printer...
Printing at 350mm/s is a whole different ballgame than 100mm/s
You'll need more heat, more cooling, prob a volcano nozzle... Can't just crank up the speed alone...

Thank you for your support!
There's already a volcano nozzle in a CHC Pro but I will continue tinkering.
