Right extruder strings in Z increments

Sovol SV04 IDEX
1

After some severe stringing on my right extruder during a print (used the left for the print, right for ‘tree’ support), I decided to make a quicky stringing test setup. A vertical pair of 2.5mm posts spaced 35mm apart. I then tried four different filaments I bought from Sovol. No comments needed on the quality, good or bad, as the tests I did do not appear to be tied to the quality or anything else about the filament.

The left extruder produced ‘fuzz’ occasionally but no little to no stringing between the ‘towers’ using a range of temps. But the right extruder did consistently at all temps. The issue at hand is how it did the stringing. As you can see in the pic, the stringing happened in regular, discrete Z steps. This is the first stringing I’ve seen on the right extruder. Any idea what’s gone wrong?

I forgot to mention that I was using the Sovol ‘brand’ of Cura. The settings for the left and right extruders were identical and using the default settings throughout.

The nozzle on the right extruder was changed out several weeks back as it was clogged, but appeared to print well after that.

Obviously you’ll need to change the slicer settings for the right extruder.

If the extruder settings won’t help then you may want to add extra filament types for the right extruder in order to minimize stringing. Here you’ll find a bunch of clues on how to do that.

Additionally, a separate PID-tuning the right extruder could help, but you’ll need to run a firmware on your SV04 that supports different PID settings for both extruders. Sovol’s SV04 stock firmware doesn’t - it uses the same PID-parmeters for both extruders.

Sorry. Thought I’d hit the button to post this.

Thanks for the feedback. I’ll start playing with the values recommended it that article.

Are you using the Cura that comes with the printer - 1.5.6 or whatever?
There’s Sovol profiles in some of the latest versions of Cura. I’m using 5.6.2 for my Sovol 06+

Hello,
You can use the last official release of Cura with the SV06+.
It works fine.
