Trying to read up on how to fix this stringing issue that I’m suddenly hitting with my Sovol Zero now that temps are dropping in my area. Unfortunately I’m getting two different answers as I’m reading up on it, kind of wondering which way to go. Figured I’d ask the folks here with more depth than I.
Last few weeks, my local ambient temperatures have reduced by ~10–15°C The inside of my printer chamber is ~25-30°C while printing. Prior during the summer months the chamber sat at ~30-34°C, no stringing issue, the filament printed fine. I’ve read two statements, one suggesting the filament is to cold to raise the nozzle temp, and another saying the nozzle is heating the filament is reaching fluid state due to printing speed and the nozzle temp. I’ll be trying the temp tower tests later today, just to see what all it tells me.
Just wondering which is correct raise or lower it, or none of the above…. or… if they both are correct and it depends on the print head being used as to which is applicable to my situation. Does Orca have a hidden winterize button LOL
Anyway kind of wondering, thought I’d ask, thanks for any suggestions.
Is the printer in the house or a garage..??
Is the glass door & lid open or closed..??
What filament are you trying to print with, PLA, PETG, ASA..??
I really don’t think it would matter too much unless your printing with ASA, ABS or some other industrial filament.
What you can do is heat soak the printer for 20-30 min before you start a print.
The printer is in a room inside a house, door and lid are closed. It’s primarily PLA, also saw it with PETG, both rolls I’ve used in the past and have established temperature profiles for. I ran out of time to test with a temp tower yesterday, I’ll add the heat soak to the test list and see if that helps, thank you.
If it’s mostly PLA, it might be best to crack the door open after the initial heat soak.
You don’t want to get a clog or start getting heat creep issues.
I had read that is a leading cause for stringing a lot of the time so I made sure to get a dryer first thing when I got the printer. The filament sits in a Polymaker dryer box 24x7 and is run each day for what ever filament is in it. Currently PLA and humidity is hovering around 18% inside the dryer, the ambient humidity inside the printer is 23%, and the room where the printer is 34%. We are expecting rain this coming week, so I’ll keep a eye on the humidity and see if I get more stringing and can correlate something, thank you for the suggestion.
I also found after a few temp towner tests I get less stringing with lower temps. Maybe I was printing right above the max temp just not sure how cooler temps could cause the strings to be more prominent, so good point, I’ll watch the humidity closer.
I’ve reduced the printing temp by 7 degrees and so far it seems to be printing with a lot less stringing. Still testing and reading up on it all but have made some progress, and at least things are no longer looking like a spider got loose in the printer!
Too hot will cause oozing which will cause string.
I didn’t mention earlier because you said nothing changed except that it was colder…
but I was going to mention it after you did the suggestions above, I just didn’t want to say too much & things get skipped over.
Hi Lion,
Indeed, my head can be like a can of dice sometimes, no telling what’s going to land especially with new hobbies! thanks for helping to keep the steps regulated.
