Stringing in the corners of print

Plugins Octolapse
1

What is the problem?

I have noticed an iissue with stringing / artifacts on the rear corner of my prints, seems to coincide when the extruder moves away / return for octolapse to take photo

What did you already try to solve it?

Reinstalled octolapse / cura etc..

Have you tried running in safe mode?

Not yet

Did running in safe mode solve the problem?

Not tried

Well that's more or less to be expected.
Depending on different variables like your hotend, nozzle, retract settings, filament and temperature your hotend oozes sometimes more and sometimes less.

Try retract on layer change and increase the travel speed.

Also I merged your posts..

I am constantly getting strininging in the corner of every print, it appears to occur when the hot end moved away/returns to the corner of the print,
Does anyone https://ibb.co/S7Gd9CWknow how i can fix this..

There is no need to open another thread on the same topic...

I've been working on this myself. Besides adding "retract at layer change" (as suggested by Printed Weezl) you can also try lowering your nozzle temp and increasing retraction distance. This might need adjusting for different filaments, since they're all a little different. I tuned some Inland PLA + to near perfection and it's running 5 degrees colder than the spool suggests.

If you're wanting to share the time lapse, you can also try hiding the mess. The goobers appear at your z seam. If you have the z seam in the back of the print and the hot end moving to the back corner, place the camera in the front and you'll not see the retraction stringing so much (or at all).

Here's some more images/videos
I have been struggling to solve an issue with my ender 3 v2 for a few weeks now. The issue relates to Octolapse causing stringing issue at the point where the extruder moves away and returns to the 3d object being printed.

Need help from an expert to help me fix this issue.[​IMG] [​IMG] [​IMG]

I have files for my cura profile and octolapse settings

Have tried lowering nozzle temperature to 195 instead of the usual 200. Still didnt work

It will be a combination of temperature, retraction distance, and retraction speed that need to be tuned together. There are test objects that can be used to adjust these parameters in your slicer and I assume those settings are somehow transferred to OctoLapse.
