New MK3S. First layer not sticking
Ran calibration wizard. It reports XYZ calibration OK and axes perpendicular. First layer test lines do not stick to sheet and appear too thin. using PETG on textured sheet. What next? Thanks.

RE: New MK3S. First layer not sticking
If you have not already done so, try using Jeff Jordan's "Life Adjust" procedure for calibrating your Live-Z setting. It is much easier to use and understand than the on-board routine and much easier to make mid-print adjustments accurately with. In general, start high (less negative) and work lower (more negative) in large increments (e.g. 0.1mm) until the filament starts to stick on its own. When you've got your Live-Z setting adjusted properly, you should be able to gently rub the extruded lines on the PEI surface without dislodging them. Then start lowering (more negative) the level until there are no gaps between layers. You should not be able to peel the lines apart after printing, but the top should be regular.

Thanks; I didn't realize just how much of a live Z adjustment would be needed. I dialed down to -1.02 to get a good first layer. Is this normal behavior?

Less than -2.0 is good
