What was your order number?  Did you receive your Press recently?  It might be from the latest batch from the most recent cargo ship.  I'm still curious if these design changes happened in the Chinese factory or if Solidoodle made these last minute changes here in the US before shipping out to customers.

I haven't checked my trimpot voltages yet.  I don't seem to get wavy lines when printing so maybe my extruder trimpot setting is OK.  But I may open up the bottom of my Press and double check the trimpots with a multimeter when I have some time.

my order number was 309xx. I was printing fine but all the sudden I started getting wavy layers, not sure why.

Hard to tell from the video.

Yes, my fan blows air into the extruder.  That was one of the last minute design revisions Solidoodle made.  The earlier units that shipped had fans that sucked air out of the extruder, and some owners manually flipped the fans themselves.  I think an easy way to tell at a glance is to look for a sticker on the center of the fan.  If you can see the sticker, it's blowing air out.  If you can't see the sticker, it means the sticker is on the side facing the extruder, so it's blowing air into the extruder.

Then this is a classic case of 'If it ain't broke- Don't fix it'. The offset won't hurt anything. It more of an aesthetic thing then an function thing.

If it does move when you touch it, Then loosen the two knurled M3 screws turn the heater block, then retighten the screws. The outer heatsink should sit completely flush to the inner heatsink.

Once again, If its not loose in anyway- Just leave it.

Thanks for the info!  Wow, all these new words/terminology (heatbreak, heater block, etc.) that I have to Google.  :-)  Lots to learn.  I'll gently twist the heater block to check and see if it's loose.  If it is loose, do I just twist it to tighten it?  Or is there a set screw that I have to tighten?

You'll want to leave off the plastic cover. It's just not necessary.

Your owl (http://m3.i.pbase.com/o9/24/77824/1/159 … _small.jpg) is very good for a first print. And you'll be able to post links soon smile

I noticed right away that my hot end is rotated and it didn't look right to me after I unboxed the unit.  Since it's my first 3D printer, I didn't know whether that was normal or not.  I looked at MacGyverX's photos and his hot end also looks slightly rotated, but not as much as mine.  Should I try to rotate it back into alignment?

To see the finished owl, go to the pbase.com website and add this to the end of the url:  /wtang/image/159546143/original.jpg 
Sorry for the inconvenience... it's just that I still can't post links yet.

Your hot end is rotated. Did you do that or did it come that? It probably works just as well, but it's odd looking.

Also, did you remove the plastic cover (with Solidoodle logo) over the extruder assembly, or did it come without?
