So, i have spent the last 2 hours trying to figure out why this is happening to my new ender 6 and i have finally found that the culprrate is the 'Arc Welder' plugin that is not playing nicely with cura and my printer.
I have use this plugin many times before and hot had an issue but since yesterday it started every print with an anoying triangle when i had a skirt set in my print for bed adhesion. I disabled the option in the this print settigns and since then there has not been any issues.
Weird.
Hope this might help somoene out there.
