I think I remember a conversation about plain glass vs plate glass...
Either way, I use picture frame glass that was custom cut to my size and it sticks very well for small-med size parts (about the size of a prusa x-carriage)
Anything bigger and I need to use masking tape. The nice part of glass however, is the nice glossy surface it leaves on the part, so I try to when convenient.

I run 11.10 and can successfully run slic3r, printrun, or repetier...
There should be no reason why your printrun shouldn't be able to use slic3r.
go to:
Slic3r Readme
and scroll down to "How can I integrate Slic3r with Pronterface?"
I'm not sure what / if any dependencies are needed, but it works good for me.

Apart from electrical issues (and admittedly not knowing about this bed), check how close the thermistor is relative to any heat source.
example-
If you had a loose thermistor laying next to a power resistor, a 20 deg jump isn't unrealistic...

Firmware - mainstream and related support
There's a maker group forming here in the valley;
Don't personally have enough time to really do anything with them, but they may be an interesting resource.
I personally started with a Prusa Mendel, and have pretty much rebuilt it piece-by-piece pulling from Prusa2 and others. I think, knowing what I know now, I would probably go with a smaller Printrbot for the hobbyist, or the Prusa2 for th

I have a bad connection that occasionally acts up and will cause just what you've shown.
Check your wires for a bad connection.

Wow thank you, luckily none of these have gone out.
It turns out that the newest Slic3r has no problems with the piece.Issue resolved.
I will get a new pic up once a chance. Thanks again for bringing this up before it became a real problem.

Plastic RepRap Parts for Sale
Yes, though I'm hearing many people are going the brass bushing route which does not use them. Its my mistake, and they will be included. I also left out the x-carriage (also obviously included). I just wasn't paying attention that day when I took the picture.
I should have an accurate picture up soon.

Super-glue has always worked well for me on small components -> pololu drivers and the like...
Bigger components, need the thermal paste / thermal epoxy all the way.

Hey guys-
Another reprapper here. Ive been up and running and making kits for a couple months now. Im also up at the U.
muffin23man- What program you in?
I wonder how many of us are around here...

After some experimentation it seems inversely proportional-
More facets = More artifacts.
Not 100% that its not Marlin, but because it seems correlated with the .stl details I've started discussion on this matter in the Slic3r area.

Firmware - experimental, borrowed, and future
Slic3r seems very sensitive to the # of facets in a counter-intuitive way. It seems that the finer resolution I create the .stl with (using Solidworks) the more arc artifacts are seen. These can range from rounding 90-deg corners, or drawing large arcs around the outside of the part.
Specifically, this seems to only be affecting the perimeter, as the fill always seems to be correct regardless.

@DaleDunn
I use SW to do all of my modeling as well, but haven't had the chance to look. Does it have the same functionality as openscad's
"$fa = 5, $fs = 0.5"
Also, if I'm following correctly; Increasing the # of facets will lower the # of arc-artifacts? or is that backwards or wrong.
Thanks for the help guys, I though I was the only one seeing this as I didn't see anyone else mentioning it.

Is anyone else seeing some "phantom" arcs? I know they are not in the g-code, but now that I've switched to Marlin I see some features connected in odd arcs... A simple example is in the "pulley.stl".
Using slic3r, and Marlin, I cannot get a print without the occasional artifacts.
I'd throw in a picture, but I tossed my bad parts... Is there a straitforward way to tune the arc detection? Or

I have seen this as well.
I have to wait next to my printer and blow a fan on the bridge because it makes the bridge in an odd direction. If you don't get the first layer nice enough, all the subsequent layers in that spot will be weird.
I lost my first attempt at this part because of it.

Slic3r
Do you need more spring tension on the wheel?
Ive noticed that I need to adjust that from batch to batch. My most recent batch needed so much more tension that I needed to readjust my trimpot on that motor.
Also, make sure that the path of the fillament is lined up well. Sometimes, mine can wander out of alignment and can cause problems.
Just some ideas

Reprappers
I was running PLA and a heated bed glass bed, but it became cumbersome heating up and cooling down. Now I print on 3" wide super-cheapo masking tape and it works great. In fact best prints come off the 2nd or 3rd re-use as it sticks well enough to prevent warping, but not so strong that the tape tears off when I remove the pieces.
Seems like people are getting exotic with their materials...
