  This made me more emotional than I thought it would; their reactions are so genuine and heartfelt. A creative experiment and the make-up artists did an incredible job. I would love to see mo...

I have a problem with dark globs at the start of a print. As the hotend heats up, a little material oozes out. When the printer begins to print, that ooze is pushed to the side and sticks to the nozzle. It cooks dark and is usually deposited somewhere on the perimeter of the print. Sometimes I can scrape I off before it does harm but some day the hotend is going to catch my hand when I am doing that.

+Øystein Krog , yea I figure a 1 layer skirt and a brim will be similar in their ability to dislodge globs, but i can put the skirt far from the object.

+Alex Cam , I'm not sure who you are replying to.  Are you suggesting that one of these methods could result in a jam?

As a followup, I made a few adjustments that appear to be helping.  I cleaned the bed real well, lowered the z a tad, and removed the default slic3r code that raises the z after homing and before heating.

I am hoping that, now that my printer is attached to a rigid surface, the z won't go out of tram as often and this fix will continue to work.

Michaels has front open frames with rounded edge glass for $5. It is no borosilicate, and can be dangerous after a few heat cycles, but the price and convenience is great. The 8x8 fits my Prusa kit perfectly.

I've been using the glass from dollar store picture frames. It's on the thin side, so not very tough, but I've had it to 110C many times without a problem.

I want to hookup some monitors to my printer displaying various currents and temperatures. I can add sensors for everything but the hotend temp. Do you think the easiest way to get at that is a raspi over USB? I suppose I could add some circuitry and run the other sensors through it. That would also give me octoprint as a bonus.

I am not sure that there will always be a computer involved, but now that you mention it, I should have some spare capacity on the ramps for temp sensors. Maybe I could repurpose it for a different type of sensor with a lookup table.

Sometimes, the simplest invention can change millions of lives. That's the goal of The Shoe That Grows, a sandal invented by inventor Kenton Lee that can adjust its size, allowing children in impoverished nations to grow up without having to go barefoot. The shoes, which come in catch-all Small and Large sizes, can grow 5 sizes and last at least 5 years.

Forget POV crashes and stunts. Attach a GoPro to a trombone and the video is hilarious and fantastic. Not to mention, has a great soundtrack

I ordered chips and guacamole but instead they gave me some sort of green salad dressing. It was a pourable consistency, looking and tasting similar to ranch dressing. Was I supposed to put it on the chips? The chips were too bland to eat by themselves so I took it back.
