What temperatures are you guys using for PLA?
I recently got my CoreOne (had MK3S before) and on some parts I noticed that the PLA profiles I used to use (which were using 215C for eSun and Hatchbox PLA) were leaving some gaps between the perimeters and the fill. I then tried the built-in Prusa Slicer profiles which use 230C for first layer and 220C for following layers and, while the gaps disappeared, there was a fair amount of small blobbing and some stringing, especially on the first layer. I understand that somewhat higher temperature may be needed to accommodate the HT nozzle, but these seemed too high. So, I'm wondering what temperatures you guys typically use on your CoreOne? Do the standard profiles work for you or do you modify them?
Thanks.

Try putting the PLA in a filament dryer for 6-8 hrs. It's probably damp.

Thanks for your reply, but my filament literally just came out of the dryer when I did this print. Are you saying that your experience using dry filament on standard profiles has been good?

I have always used the stock profiles for PLA (Prusament and "generic") on the Core One, and have been very happy with the results.
Small bubbles, blobs and stringing are a pretty telltale sign of damp filament in my experience. When you mention "came out of the dryer", are you referring to an actively heated dryer or to a sealed box with desiccant? The latter is good for keeping dry filament dry, but does not remove much moisture once it has been absorbed into the polymer matrix.
RE:
Same with regard to stock profiles. I've found that PLA is PLA. There really isn't much difference between vendors for standard PLA. Unless it's a special PLA like matte, CF, HT, HS etc.
If it did come out of dryer. what temperature were you drying it at and for how long?

Thanks. I typically dry PLA at 45C for 6hrs, but I now realized that one of the 2 spools I used (it was a 2-color print) was just in a sealed bag and was not dried. So, it's possible that this was the problem. I'll try it again after drying it and see how it comes out.

I find the profiles for the high flow nozzle work well. I don't even take much care with drying PLA. My room is 36-40% RH and I'll leave filament on the printer for many days at a time. A while back I printed a temperature tower and was surprised that there wasn't much difference top-to-bottom. Some, and I want a strong part with good layer adhesion, but cosmetically there was little to choose from. My most used PLA is inexpensive black Buddy3D from Prusa.

Unless you live next to the ocean or in a rain forrest, PLA can last weeks to months without having to throw it in the dryer.
