Just did a test on glow paper testing out:
1) Why was it small?
2) Where's my freakin' rafting!

1) As for the size... I still have no clue why this happened. It was "actually" only about 20% smaller than it was suppose to be.
My test on glow paper printed at the exact size it was suppose to be.

2) I decide to generate some new gcode and slic3r crashed on me. I restarted slic3r and reset the print settings (they go back to defaults when you restart the program). That's "print settings" not "Printer settings" just to be clear. I then created my gcode, opened it in the Peachy software and ran the print.

The rafting printed !

My guess is that 3lic3r was misbehaving as I had it open for about a month on my laptop.
Mental note: Restart Slic3r before generation gcode ;-)

more to come...
