The new update has a memory leak issue. If you drop a model on the visual table, slice it, then exit preview mode and remove the model, the task manager shows the Simplify3D task's private memory usage does not go back to what it was prior to attempting the slice. What's worse, if you do this 3 or 4 times with a large model, the amount of memory tied to the process keeps increasing each time. I ran into a situation where I was just testing the slicing of a few models without actually printing them and then loaded one model I wanted to print but was experiencing weird temp fluctuations to the point I could not get a nice print. I closed out of the software then reloaded Simplify3D and put that model back in to slice/print. This time the temps stayed within +-2 degree's. At first I thought it was just a glitch but I have been able to reproduce the same results over and over again. And in the process had Simplify3D lock up to the point I had to use task manager to kill it. I never have any issues if I load the software, load a model, slice it and print but if I don't close out between print jobs, the memory usage keeps climbing. I've run extensive memory tests on my PC to rule out bad memory modules and have no issues with the test or other 3D software.
It show's to go you how feelish you fool when your tang is all tungled up and you bart stalking tackwards!
