I had the setting on the printer set to check the bed and extruder temp every "0" seconds, so it was constantly struggling to read the temps every possible moment, "clogging" the connection it feels.

Anyways, I turned that off and now it seems to be working a lot better.

lol, don't think it's computer issue anymore.

In the Printrbot video it looks like it is jittering a little bit going around the curves.  I've seen that happen when it seems like the computer isn't getting commands to the printer fast enough.  Straight lines are easy because it is a single command, but curves are a lot of little lines in a short time.  You can try making sure the computer isn't doing anything else that might peak the CPU, maybe try a different usb port or cable.  If you have any way of using an SD card, that might work better.  Also check that the baud rate is 250000 or whatever the Printrbot requires.

I believe there is a way to use the SD Card slot on the board to print from, I'll have to look into that.

In the mean time I'll try swapping USB Cables. Also double checking the baud rate. I'm printing from a Mac Mini that's pretty supped up. It's got a 2.7GHz i7 w/ a 1TB Fusion drive and 16GB of RAM. It's pretty much used just for 3D printing.

It prints straight lines fine, here are some pictures. Any ideas on why this is happening? I'm using the stock slic3r settings I believe, with Repetier on a Mac.

May we use your pictures to help people who suffer this problem in the future?

Please do! And let me know if you want me to take any more.

So when I first started that print it took a bit to heat the nozzle and get it moving.

Anyways, on the Printrbot Jr I am printing .3mm layer heights, but I don't think the nozzle is hitting what it's printing. I stopped printing those feet for the Printrbot and switched to something square and it printed it fine without any problems at all.

The filament is 1.75mm PLA, printing at 190deg I believe. Whatever the stock settings for the Printrbot are.

What temperature are you extruding at? Is it PLA or ABS? It looks like you are trying .3mm layer heights. Is that right?

check extrusion rate and search solution for Z wobble.

Looks like this is also happening to some extent with my Printrbot Jr.

Check out the video:

And then it printing straight lines without any trouble:

They could be marks from the nozzle hitting the filament. You might want to back off your z-axis.

I've printed it dozens of times and on 4 different printers. Never seen anything like this happen.

I first noticed this happening when I tried to print something that was a circle, and thought it was a bad STL. So I busted out my tried and true and it happened again.

I have a Printrbot Jr. here as well, and it's printing some circular things as well. I'm actually noticing this same effect happening, but I didn't before this. Could it be a problem with Repetier (I'm using Repetier to control both the Solidoodle 2 and the Printrbot Jr. at different times)?

Any thoughts are helpful, thanks! I'll upload the files that are acting weird just in case.

It won't let me upload the octopus stl file...

I think after 5 or 10 posts you are allowed real links. What software are you making the stl's in?
