Hello,

I am semi-new to 3D-printing.
When I first got my printer, a Flashforge Creator I had no problems printing whatsoever.
Now, after a few months of pause, when I am printing flat surfaces, the strands tend to
break and curl up to small lumps so that the print nozzle bumps into them. I hope I make sense,
let me know if I should attach a picture. I am printing ABS at 240 deg, feedrate 40 mm/s.
First layer looks like crap but sometimes I can get away with it just let the printer go on.
Other times it messes up the whole print.
These values worked good before, as far as I can remember. I have tried going down in
temp and also up/ down in feedrate but the problem persists. Does anyone know why
I am getting this problem? Thanks.
