newbie, terrible prints - clueless whats wrong

Hey folks,

I'm having trouble with my newly-built MK3: It goes through all the calibration steps a-ok, but I had a lot of trouble getting the first-layer calibration to look good (ended up with a value of 135 which seems a little high and still doesn't look wonderful).

Now trying to print the "bat" example, and its failing almost immediately on first layer - seems to be a combination of not sticking to bed correctly and there being a lot of gaps between the lines (attached).

Printer is configured stock, using included PLA.

Anyone have any suggestions?

Replying to myself here.

I just found this post: https://shop.prusa3d.com/forum/assembly-and-first-prints-troubleshooting-f62/resolved-batman-logo-first-print-fail--t17618.html

which seems *very* similar to what I'm seeing. Looks like I may have my z-offset way too high (I'm at -135, that post talks about being up in the 700-800 range) - gonna try lowering it down a lot more...

First sign of Madness, Talking to yourself...

Second sign... Listening to the Answers!...

And you bought a 3D Printer....

there is no hope for you Duncan! 😯

Seriously, I hope your changes reap benefits...

I was going to suggest lowering your Live Z

but your sub conscience got there first...

Have you seen this thread?

might help you improve the first layer!

Thanks for the tip Joan! - I'll def. follow that thread to fine-tune my first-layer height.

Following up - my very first print just finished, and while not perfect I think it's pretty good for out-of-the-box settings:

Any suggestions greatly appreciated.
