I can’t figure out what is causing this. All of the sudden my prints seem to have this line about the same height all the time regardless of the model (though I don’t always notice it in some models) or filament brand.
I already tried redoing the belt tension with the back screws etc… I replaced the hotend (it was slightly bent), calibrated… recently cleaned and greased the Z screws.
These things do not appear to have resolved the issue.
Just to be sure I tightened the back screws again to adjust the belt tension then ran the self-test.
Then I ran a flow calibration… trying a benchy again. But so far, no matter what I have tried, the problem persists.
Update: the benchy has the same line still.
The rest of the print looks fantastic. I’m stumped and can’t figure out what’s going on. I did have a couple of firmware upgrades recently… hope someone can help
I don’t know if belt tension has anything to do with your print problem, but just to be clear, tightening the screws does not change the belt tension. The belt tension is determined by springs. Loosening the screws allows movement of the adjustable pulleys, gentle manual movement of the print head overcomes static friction in the pulley mounts so that the spring can apply the correct tension and then tightening the screws clamps the movable pulleys in place so the tension does not change while printing.
@colin.small I think I just found my issue, the small bolts securing the hot end had rattled loose (this is actually second time this week ) maybe worth a check if you haven’t already.
One is the benchy hull line issue that I referenced. That seems to not be the fault of the printer at all.
The second issue seems to be related to the specific model I am printing, so I’m not sure how to resolve that. But other models done seem to have the issue.
