I am using a TAZ5, MAC MINI, OS 10.10.5 AND CURA 17.1.
My problem is that if I start Cura, load a file and print it, all is fine. If I then clear the platform, load a different file and print it, I get the previous print. In order to avoid this problem, the only fix I have found is to quit and restart Cura. (Cycling the power on the TAZ does not help.) This is inconveriient, and requires that I re-setup temperatures, etc. There must be a better way!
