This what is happening. http://youtu.be/UV9bTwRjyto. The video has been slowed to 50% speed.
Assumptions & Known Settings:
Sliced by Slic3r:
Config, slightly modified draft settings from website I can post them tonight.
Extruder temp 230C
Hotbed temp 88C (I have had some success having slightly higher bed temps)
I apply ABS/Acetone slurry all the time, maybe my batch is getting old or bad.
No drafts or fans running in my room
First layer print % if I recall was 60 or 65% of solid infill speed which is I think 120? (probably slower though cannot recall).
Operation by Printrun
So the print started with the outline then the hole in the middle and moved out from the center. Thus note that the first chunk of passes around the hole are flat, fully adhered to the surface.
My bed is leveled, not as low as I would like but if I don’t have it index card thickness leveled (if I go to say thermal paper low) I get (and even now get) the extruder head rubbing atop already printed material when it is doing none-print movements.
This seems to happen only when the lines are long and straight, smaller infills do not seem to (usually) have this problem.
I am ordering a fresh set of PET sheets tonight and plan to work on upgrading the printer with some of 1010’s upgrades and first build a very elaborate enclosure for the unit.
So who wants to give me advise or help.
EDIT 8/2/2013, This evening when I get home I will be sure to dump the slic3r config, model file etc.
