Bad quality print

Hi there.

Im having issues with print quality .

I recently installed linear rails on the bed of my ender 3 v3 ke however im not sure if its related.

Please can someone advise

Hi
I quite often get this on the 1st layers. As far as I can tell it is caused by the Z offset being too LOW.
Did you do a full bed level and auto Z axis calibration after fitting the linear rails?

Try raising the nozzle by .02 -.05mm and try again.
Also worth checking temperatures, bed and nozzle.

Can you tell me the software and version you are using?

I am using the creality print slicer software.
I have tried it on the latest version of creality print 5 and on the latest version of creality print 6 .

Please advise

I have done all the tests and calibration again including input shaping with the g sensor.
Any other suggestions please?
