Auto_Bed_Leveling: Enhanced G29 command

I appreciate your time. I'm not a noob. I just can't seem to get things settled in.

Here's a screen shot:

The Slic3r default recommended is 0.35. Maybe I'm misunderstanding this setting for 'First layer height:' and need to set it to be 0.20 also. Is that what you are trying to get across to me? Now that I think of it, if the 'First layer height:' is set to 0.35mm, then the hot end needs to be 0.35mm away from the bed to do that. Hmmm, this is probably it now that I wrap my head around it.

Off to do a new test. Thanks for checking in and getting me to do better analysis of parameters.

.35 is not a bad first layer height. Can you paste about the first 25 lines of the generated gcode here, so we can see what Slic3r is outputting? And yes, if your first layer height is set to .35, then the first printing move should place the nozzle .35 off the bed.

Understood. I'm getting predictable performance now. It was all about that 'First layer height' that I was misinterpreting. I have my paper gap (just measured that paper and it's 0.11mm) so I''ll now respect that 'First layer height' properly. Thanks for all of your guidance. We all know a lot of stuff but none of us knows everything. That's what makes forums so powerful. The expertise that is shared in collaboration is just priceless. Sometimes we get so wrapped up we can't see the forest for the trees.

Thanks again. I'm really pleased with the consistency in gaps that I'm getting now.
