I am facing nozzel height problem in printing. I am using inductive sensor for z height. I have set up Marlin and also using G29 command nozzel height and z-offset is calibrated (my z-offset is 0.1mm). While z-offset calibration, I have adjusted z-offset so that only bussiness card can pass(i.e. 0.1mm). But while actual printing, nozzel stops at somewhat 8-10mm away from heatbed and material falls from 8-10mm onto heatbed. I don't know how it is happening.why nozzel is not coming to 0.1mm while actual printing and why it stops at 8-10mm aways from heatbed? I am unable to resolve this issue. If you can help me in this case , I will be grateful to you. Please kindly help me.
