Stringy bottom

Okay, silly question...What is half a flat? Is that a half turn of the bolt?

[jimc]

no thats 1/12th a turn. 6 flats on the head of a bolt or nut.

haha jules thats funny. screw it down and the gap gets tighter. loosen the nut and the gap gets bigger. r

Like I said....dyslexia. It literally took me hours to set the gap the first time I did it. (Or maybe its a girl thing - can't tell you how many freaking screws I've completely stripped out in my lifetime!)

[scampa123]

yes.

nothing wrong with doing it in software the way jules does it as long as that work for you. i just could never remember what was the correct offset when switching between profiles.

I had to set up and save separate profiles for each filament, otherwise I'd have forgotten by the next day. (On the other hand, I could never do it your way, by turning the nut, 'cause I seem to have some kind of dyslexia about which way to turn the darned thing to tighten it! )

The only thing with the profiles is that if you have a bunch of processes in S3D defined and you modify the profile you can easily, inadvertently modify the changes. S3D notices that a change was made and asks you if you want to save the changes to the profile... Just have to be careful not to overwrite the correct settings!!

btw going back to -20 gets me back to the correct height...but I notice the lines in the bottom of the calibration square...maybe there is an infill setting I should be playing with??

Post a closeup picture of the bottom of the last square, let's take a look......

Here it is!! Is this bad? It's not a glassy bottom for sure..

Hmmmmn - that still shows that the bed is a little too far away. (Much better than it was, but there is still some under-extrusion.)

Let me ask you another question - what extrusion width did you set? (0.40 mm?)

[jimc]

yes still too far away. move it about .05mm closer and try again

Yes, 40mm manual

Yes but if I do, then the height of my calibration square will be off...

Maybe I should adjust the bolt and use a .1 or .06 feeler gauge instead of the .15?

Also, when I set the Z via the bolt, I'm doing it with both the bed and the extruder fully heated for ABS at the temps I print at...I assume that's correct from what I've read on the forum
