Beginner 3D printing, Ender 3 V3 SE issues

[Bikeracer2020]

Perhaps try to print a plain test cube and make sure if you can, that the slicer settings are the same as the successful benchy or dog print.

Double check that the nozzle and bed temps are okay.
Also try printing on a different part of the bed.

I think if one thing prints okay and then another one does'nt it could be the particular slicer settings.

Hi. Thanks for the info and suggestions. I fixed the problem by flashing the firmware from 104 to 106. I think this made the Z-offset more accurate. It definitely dropped it slightly. Printer is back to running perfectly. :-)
