Severe Ripple in First Layer
Can anyone help! I have ripple in the first layer that causes prints to fall off the bed. This happens with all extruders. I have Done/ Checked the following. Complete factory reset and calibration, firmware update, bed and nozzle temp., Live Z adjust, belt tensions, extruder tension, PINDA adjustment, frame checked, changed filament, checked hotend for mechanical problems.

This looks like the extruder is too close to the bed
Reestart the same print again. And as it starts printing back off the live Z until the waves dissapear. Then back off a little more until your extrusion lines statr to separate. Into individual sphagetti.
You are now too high so increase the live z value to about half way between wwhere rhe waves stopped and the spaghetti began. And you should have a good first layer.

Thanks, I tried that just now to make sure. The ripple occurs no mater where live z is set. even with live z at 000 and individual strands visible.

Problem solved. Replaced left Z trapezoid nut and left and right LM8UU bearings in the Z carriage. Smooth first layer now.
