I've got Problems with overextrusion which are not cured by your profiles. When I adjust the acceleration to e.g. 5000 mm/s² for perimeter the problems are gone?

Just imported them to Prusaslicer, 'bout to print upgrades, thanks for the help for newbies like me.
have a wonderful day :D
Bonjour,
Merci beaucoup pour le partage.
Si nous souhaitons l'utiliser pour la Kobra 2 max nous avons juste à modifier la taille du plateau et la hauteur ? Aucun autre changement particulier ?
Merci par avance, :)
@TheMajestic_2496411 Oui, c'est correct, c'est uniquement la largeur de la plaque et la hauteur qui doivent être ajustées.
This is the same profile for PLA and PETG? I mean, If I print PETG I must change temperature in settings ? THX for help.

@ukaszKoszkin_1923299 You've used incorrect import option. You need to import config bundle, not just config
Working on tweaking a Kobra 2 Max when I came across this. Is ArcWelder still required when you have the 'Arc fitting' setting enabled in Prusa Slicer 2.8.0?
@Rysten_41779 Arc fitting and ArcWelder will give different results. I still highly recommend ArcWelder over Arc fitting.
I noticed that in the printer settings you use Lift Z (movement of the extruder along the Z during movement), is this setting important at such low speeds (60 - walls), and in general, would it be advisable in your opinion to use Lift Z at higher speeds (with Default profile Anycubic 0.16 speed - 300)? I think that movement along the z axis when moving the extruder should be used just like that at higher speeds due to the fact that the nozzle can touch and destroy the printed model. I’m also waiting for your updated profiles for slicers🙂 (edited)
can you update the files for anycubic slicer 1.4.3?
@keybl_2030253 I'm testing some settings before I have an update ready, should be ready in a few days
A tip. The gcode for this doesn't heat the bed and nozzle at the same time. The factory Anycubic config does.
Change these lines in the gcode under printer settings -> custom gcode
NEW:
M104 S[first_layer_temperature] ; set extruder temp
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M109 S[first_layer_temperature] ; wait for extruder temp
OLD:
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M104 S[first_layer_temperature] ; set extruder temp
M109 S[first_layer_temperature] ; wait for extruder temp

@Friis_1591774 The official Prusaslicer profiles downloadable from Anycubic are set up like this. The power supply issue is very old school back when an Ender had a small power supply. On the Anycubic the bed is heated a few seconds before the nozzle.
@AaronVanClev_1835981 Power supplies are with more capacity than earlier times, but it is still a cheap power supply, you will end up current limiting it, possibly extending total heat up time, by heating both simultaniously. I'll rather play it safe on a public profile. The hot end will reach 210+ within a minute. But, thank you for the suggestion.
Another option could be to insert a timed wait command, something like 45 seconds, before heating the hot end. That'll eliminate the risk of clogs, or degrading the filament in the nozzle.
I am still having overhang issues. Any suggestions? Also that fine stringing.

@Friis_1591774 This is Anycubic PLA. 205º. Using the settings in the profile downloaded here. (edited)
@AaronVanClev_1835981 I tried white PLA from Anycubic some time ago, I gave up on it. It had very poor bed and layer adhesion, warping and stringing problems. As far as I remember, I had to dial it down to 190-195º.
I would start with dialing in temperature with a tower print, and also calibrate retraction. Retraction settings will vary from brand to brand. White is more abrasive than other colors, it's usually made with titanium dioxide. So, even between white and other colors within the same brand it might be worthwhile calibrating them separately.
Try reducing overhang speed by 10% decrements. (edited)
Thank you so much for the new updates! I really appreciate your work! Your result is the best when compared with other participants. You are the best!
@OlegZinoviev_1917974 Thank you Oleg ;)
Im gonna try this becouse i have a lot issues with bridging... Do you think yours profile can help?
@KasztiParalo_1503874 not an easy question to answer, some filaments are more difficult than others. Are you printing with PETG?
@Friis_1591774 no, with PLA. Already printed some things on this profiles and looks better
Thank you! I'm getting my Kobra 2 Pro soon and will use these for sure!
Wondering if Arc Welder is still needed now that PrusaSlicer has Arc fitting functionality? (edited)
@Lorenzo_121038 In my experience, yes! Arc fitting is based off arc welder, so it's easy to assume that it would do more or less the same. Tests I've made between the two yields better results with arc welder, with very clear differences between them.
@Lorenzo_121038 Neither is strictly needed, best advice I can give is run tests with each, and also include test without either of them (edited)
