Build up on corners and curves causing prints to fail.

[bodoo]

Printing things with a large base has been no issue for me yet, but I cant seem to print things with a small base, even with a raft. I'm new to 3d printing, and I can't seem to findout why its doing this. Currently I'm printing at 50mm/s and 80mm/s travel. 230 extruder temp, 112 bed temp. I've tried faster movement, 80mm/s for both feed and travel. I tried playing with the bed temp as well, moving it up to 115 and 120, both with the same result.

The extruder ends up catching the build up and pulling the print off the board.

ABS or PLA? I have been running all my ABS at 90c lately with machine enclosed.

does it seem to help running the lower bed temp? What differences did you notice between 100 and 90?

I use ABS.

90c bed temp? Any sticking issues?

[bodoo]

I'll give 90c a shot.

No problem. On 3/16" Borosilicate Glass (Pyrex), generally use glue stick. Some times use abs slurry.

tried the 90c bed temp and still got the issue.

a more severe case.

Could be a lot of things. What software are you using to prepare prints? Filament density calibrated? What retraction settings? Is the printer fully enclosed?

[bodoo]

I'm using replicator g to prepare the g code, I'm not sure about retraction and filament calibration though.

any chance of a photo that's more print than hand.

Apart from a slight curling can't see any obvious issues. But then you can't really see much of anything, printwise.

Also try using makerware 2.4.
Rep-g just has too many issues to bother with :-)
