Infill vibration issue.
Ok so still having this really odd issue.
Halfway through a print and always on the infill the hot end starts grating across the print and sets up vibration to the point I have to stop the print.
It doesn't do it on the walls or details always on the fill.
The bed is level (4 times)
All the bolts are tight.
Z hop enabled and disabled.
Decreased Z-offset to check level/height and the brim went all stringy and not squished together and had the same problem.
Increased fill from 20% to 50%, same issue.
Printed in different sections of the bed.
Always the same problem, always only on the fill.
Trying to post photos but not sure I can.
Any help would be really appreciated.
