I have just updated Z-Suite from ver. 2.7.1 to 2.8.3. I printed a file that I had printed before and found that I could not separate the print from the raft. I printed a second time, making sure to take it from the printer as soon as it finished (previously I had left it for some time) but it did the same thing. So I went to my second computer, which still has ver. 2.7.1 installed. I recreated the print file and printed again. The print came away from the raft as easily as I would expect.
Is this a bug in ver. 2.8.3? I do know that I will be looking to roll back to 2.7.1 if this continues on other models, even if it means a complete uninstall and reinstall to do so.
