Can someone interpret this very first print?  

RE: Can someone interpret this very first print?

And here is my second, the frog... are these considered good prints?

RE: Can someone interpret this very first print?

Better than a lot of the first prints we see here.

Your first layer is not quite squished enough.  Run the first layer calibration again.

At the end of the calibration you are aiming to print a single layer *sheet*. It should be possible to peel it off in one and fold it without the threads seperating. If it breaks into lines it is too high, not squished enough. If it is a single sheet but with wavy lines or drag marks on it you are too low.

For most people it pays to use 7x7 mesh bed levelling; activate it with the LCD menu..

Many beginners have problems with the built-in first layer calibration routine. There are alternatives, see this page by a regular poster here:

and look at this thread:

If you are still unsure show us a picture of the bottom of a suspect print.

You are definitely in the ballpark.  I would echo the suggestion to switch to 7x7 bed leveling and to do a more rigorous Z calibration with any of various test prints such as the one used for the My Way cal.

@diem

Thanks diem, appreciate the sound advice, have also printed benchy which I will post shortly, but will try ther 7x7 and recal z

@jsw

thanks jsw, I am on the path to 7x7 and recal

And here is my latest benchy

May we see the bottom?

Cheerio,

@diem funny you should ask, was just doing that 🙂

Still think your first layer needs some work.  Not a very clear photo but looks like needs squished more.

Use Jeffs method, as Diem says need to be a solid sheet, after reading jeffs instructions skip to pg40 and look at Joans photos, very clear description of what you are looking for, takes a bit of time to nail the first layer so dont rush it.

I know its fun to print, but without a good first layer your ptints may fail.

RE: Can someone interpret this very first print?

I agree with @clarmrrsn, your first layer needs attention. It's close but I would expect problems with taller prints.

Cheerio,

RE: Can someone interpret this very first print?

Thanks for your help everyone, I've got some research and calibration to do thanks to all of you, really appreciate your insights.

RE: Can someone interpret this very first print?

Thanks again everyone, I posted at the other forum, getting some strange results when I retry printing at an offset that previously worked and when retired did not... here is a pic...

The right print is the original that did well at -1.195, the one on the left is a second attempt at -1.195 to get a more accurate setting and you can see the quality is nothing like to first -1.195 print... sigh.
