I am trying to print a rather detailed model of bones in ABS on a Flashforge Creator Pro, using Simplify3D v 3.1.0.
As the print progresses, the edges curl dramatically. Eventually the print head catches these edges, ripping components from their supports. This typically occurs within the first 11% of the print. (I have not bothered to determine the exact layer(s) at which the components catch.) The edges are not curling on the heated bed; indeed they stick rather nicely.
I have read the quick start guide and the Print Quality Troubleshooting Guide.
I have considered that the ABS may be cooling too quickly, causing the edges to curl before the next layer can be deposited. To that end, I printed several test cubes at different temperatures around 230º in 5º increments. I see no discernible difference in the output. The result is always a wide base with sides that narrow toward the middle and widen at the top. The corners curl up, giving edge lines a rounded appearance.
I also considered that the acceleration setting on the printer may be to blame. I turned off acceleration and printed another test cube. The speed was clearly more consistent, but the end product was no different.
Am I right in thinking that the problem here is due to the ABS cooling too quickly? Whether yes or no, does anyone have suggestions for how I might solve this?
I attempted to attach the factory file for the bone model, but it is too large to upload here. It can be downloaded from my dropbox at: https://www.dropbox.com/s/5isxukrwmlyug ... ctory?dl=0
Thank you in advance for any help.
