Topic: Extruder head unseating prints

Especially small prints.

I have a solidoodle 3 with the provided black filament. Large prints seem to work okay, and there's almost 0 warping now that I have a bottle of isopropyl to clean the surface. But a lot of times the extruder head will cause a part to come unseated from the print bed.

this happens in one of two ways: either the part has an extruding portion caused by the extruder placing some plastic on a sensitive part then immediately jerking off to another section of the print, pulling the sensitive part up in the process, which then catches later on down the line, or the part will just come up randomly in a print.

The temperature of the build platform (100 C) seems a little weird to me - I've never heard of an ABS build platform temperature so low. My platform won't go above 103, and I'm kind of scared I'm pushing the platform to the limit with that. I don't know what else to do though. I can always remove the parts by hand, regardless of how hot the platform is or how well I clean it. I recently leveled the build platform, without any luck. Are small or tessellated builds just out of the capabilities of the solidoodle?

Re: Extruder head unseating prints

a couple suggestions. The first would be to slow down the speed for travel a bit(under slicer settings). This should help with the sensitive parts issue. The other problem is one that I have encountered repeatedly. They tend to be either to close or to far away from the bed. To far away and the plastic creates globs that do not stick, instead pulling them around. The other is to low, with the print picking up any little lumps caused by the extruder putting more plastic than the space allows. If the parts are always coming right off easily by hand, then you probably need to adjust your z screw up a bit, so the extruder is a bit closer to the bed.
