I was recently asked to split a model for a client and the part had such a high face count that solidworks couldn't work with it (it could be a mesh but would not turn into a surface or solid) and meshlab would crash when I would try and reduce the face count. According to meshlab the part had 1.7 million faces.
I have had a printrbot simple metal with a heated bed with very little issues when I was using the old UBIS heater. However I recently upgraded to the ubis 13s and every once and awhile I get temperature graphs that look rough and like it cant maintain a correct temperature. An example of this is shown in the figure. It only does this for about 15 min every 45 min or so.
