First print-- issues with tallthin.g from the SD card...

[jsc]

Other->Default Printing Speed.

After watching every failure I don't think I have a bed sticking issue, I think it's something else. Filament isn't lifting after being placed down, it isn't being placed right in the first place.

That is the definition of a bed sticking issue: the filament doesn't stick. If you want to try something else before you get your glue stick (Elmer's Disappearing Purple, get the large size) and see all your issues just go away, you can try this: take your glass off, take it to the sink, and wash it super squeaky clean with dishwashing detergent. Let it dry, handle carefully by the edges, and put it back on the printer. Heat to 60C. Repeat after every few prints. OR, use gluestick or hairspray.

Seriously man I don't know what you fascination is with printing on bare glass... no one here does that because it's not a reliable way to go. You keep asking for advice on how to fix your problems but your just not taking the advice we give. Most of us have been doing this for quite some time and have been through all off the same problems at one time or another that's why we know how to fix them. The only setting you need right now is to.... Go get a damn glue stick. If you can't get PLA to stick your going to have one hell of a time trying any other type of filament in the future.

Get a Elmers Purple glue stick and with the bed cold lay down two light coats just where you are going to print following the pattern below...

The first coat go up and down and the second coat go side to side, do both coats in one continuous stroke without lifting the stick. Lay it down light, the glue stick is purple but it should go down clear, if your laying it down and it's laying down purple your putting it on to thick. (Just keep in mind when using a glue stick for adhesion never force the print off the bed, just let the bed cool and it will pop of by itself. (Cracking sound is normal... be patient.)
Once all that is done go back to the Guide and print some calibration cubes to get your extrusion set and your Z-offset. (It sounds like a lot but once you do it a few times it becomes second nature.)

When I do this, should the lines in the diagram you posted be only where the glue is? Or should I basically fill the bed with a light layer?

First attempt printing the tool holder after applying glue stick to the bed...

You can see where the filament gobbed up and/or didn't lay down. Sooooo..it's not bed adhesion. What next?

More glue stick. You will notice that your latest print looks a lot better than your first. Apply the glue stick over the whole surface, leaving no areas bare.

I just did that and tried printing the same part again. This time it started the skirt but wasn't laying down any filament. Was basically just making a line in the glue. I didn't apply that much either. You can see there's glue there but its not purple or anything.

Put a thicker coat of glue on the glass and let it dry completely. (No purple.) Make sure that you have the thick layer of glue all the way out where the skirt is printing.
Heat the bed up to 60°C before you start your print.
Slow down the first layer speed to 50% of whatever you are using for the regular printing speed.

If you don't get it to work with the glue stick doing those three things, go buy a can of hairspray. (It's easier to apply evenly and thickly than the gluestick.)

I just slowed printing down majorly. Based on the color codes in S3D, it's printing at around 3.8mm/s. The first layer circles were where it always messed up on this object. So far so good. But it hasn't completed the first layer yet.

I shouldn't have to slow things down his much, should I? The creator of this on Thingiverse recommended these settings...

Print Settings:
PLA
50 mm/s perimeters
70 mm/s infill
100% infill
.2 mm layer height

I have it set to < 30mm/s, 30% infill, and .2mm layer height.

Did you let the glue dry? Heat the bed up to temperature?

Applied glue, let sit for 5-10 min, heated bed to 60c.

That is for regular printing. First layers are often slowed down to give the filament thread time to stick to the adhesive. But 3.8mm/sec is ridiculously slow.

You might want to experiment with that and vary the speeds while increasing your adhesive thickness until you get to a point where everything sticks, but you aren't limited to a snail's pace.
