Topic: Solidoodle 4 parts tapering?

I have had my SD4 for over a yr now and its been working great, but lately i noticed on thinner parts, they taper out as they build up, any ideas on a fix? I am thinking its the printer as the part looks good after slicing, but i could be wrong. Thanks in advance

Re: Solidoodle 4 parts tapering?

as you can see its not crazy much but it is the whole way around this is the worst spot, like i said not all parts just noticed on thin parts like this one. http://soliforum.com/i/?o6Pr6mf.jpg

The picture's a little blurry, but I'm betting that the right-hand side of that part in the image was the bottom layer.  If so, what do your bed temperatures look like in your slicing program of choice?  I over-insulated an enclosure once, for my venerable Printrbot LC, and this would happen constantly until I lowered the temperatures in the bed. 

The cause seems to be that, with too high a bed temperature, the bottom layers don't expand as much as the higher layers (that are cooling at a more proper rate).  On my Solidoodle 4s, I keep the first layer and overall bed temperature at a constant 105C and it prints like a dream.
