Your printer is supposed to be able to create a solid outline on the bed of your printer. Sometimes, though, your print will have little gaps in it and it will look like Morse Code. Most of the time that I see this, it is the result of a user having changed something regarding their extruder. Their gear may have worn out and they replaced it, they changed filament or nozzles and forgot to calibrate their e-steps, or their extruder is starting to fail.

For troubleshooting, first make sure that everything is mechanically sound. Take a look at your extruder gear and make sure it’s not missing any teeth.

Once you have determined that everything looks good, calibrate your e-steps.
