S3 wider line at start of each layer - heat creep ?
It is a layout jig so need accuracy - long and thin - the 3mm wide splines are coming out at 3.5 then 3.4 down to 3.0. Changed everything - glass, cores, 1 / 2 sides. AA 0.4 , Cura latest , UM PLA. It seems to be heat creep whilst the head is travelling all the way back to the start maybe ?
The skirt prints wider for the first 5cm or so. So once the skirt is finished it is the main print which prints wider. Hence the added 0.5mm.
Or is the machine just getting old ?
( the prints are stopped after a few layers to show the wider line width - should be 3mm thick , 3mm square actually. The little blobs are small infill areas - I got rid of them in the gcode, I thought maybe the lingering was causing heat creep, but didn't fix the problem )
