Hi-

I was wondering if anyone has ever tried the change filament or the pause by height/layer modifying the g-code using the Cura slicer. I’ve tried to use those two processes but the machine will not pause and will keep on printing until finished. I’ve tried this on both my SV01 and SV03. with no success.

Make sure that you use the pause function for Marlin. I‘ve been using it for multiple times on my Sovol sv 01 Pro and it works well.
