First layer issues, when do you stop re-leveling?

[Alan]

We wanted to start a practical first layer thread for the 3D Printing Forum

If a print fails on the first layer, what do you check first, second, and third? so you don’t waste a whole night tweaking the wrong thing

I’m trying to build a boring but reliable flow like...

• Clean the bed
• Confirm bed temp and nozzle temp
• Adjust z offset slightly

Then only after that touch speed, fan, or anything else.

What’s your version of that flow for PLA and PETG? And what’s the most common thing that makes people think it’s leveling when it’s really not?

Share your checklist in the order you actually use it, not the perfect textbook order.

My flow is bed clean, confirm filament and bed temp, then a slow first layer test print while nudging Z offset. If that still looks bad I check extruder tension and if the nozzle is worn
The trap is chasing mesh leveling when the real problem is under extrusion from a partial clog or the extruder gear chewing the filament
