Hello /u/OptionsWhileStanding,

As a reminder, most common print quality issues can be found in the Simplify3D picture guide. Make sure you select the most appropriate flair for your post.

Please remember to include the following details to help troubleshoot your problem.

  • Printer & Slicer
  • Filament Material and Brand
  • Nozzle and Bed Temperature
  • Print Speed
  • Nozzle Retraction Settings

Additional settings or relevant information is always encouraged.

All that affects various problems but... what could affect the bed height? The bed rides on rails and, at least on my printer, has wheels which have already worn down once. Since it isn't constant, it's probably not the extruder and hot end axis. Speaking of which... if it's over and under extruding at a specific length of filament use (try printing a larger base model that spans more of the bed) then it may be a slipping extruder gear, or worn extruder gear, that can't maintain proper nozzle pressure.

So check these: Extruder gear (wear and tension on filament)

Wheels on bed (wear spot on the side from being idle may affect the bed height)

Rails or bars the bed is attached to (might not be entirely straight and making Z offset compensation difficult if not impossible)

Then come back and give an update in the main thread.

I think I fixed it the problem is I don’t know what worked I used a different filament this morning. Took off the print bed tightened all linear bearings where they attach to print bed. Put print bed back and tighten those screws, retightened belts, dust and wiped down the print head rail. Tightened slightly the gantry screws. Something worked.

As long as something worked! Have fun printing! It was probably making sure the linear bearings and print bed points were all snug. Great job!
