If I print something, I find that I cannot do another print unless I quit Cura altogether.
Example 1: Suppose I print something and decide that more support is needed. I add more support, and confirm via the levels view that the support has expanded to include the trouble spot. I press print again, and get a duplicate of the original print, with the original (and nonoptimal) setting.
Example 2: I print one part. After removing the part, I choose File > Clear platform and then load a new model. I press print and it prints another copy of the first part. OR, sometimes it prints both parts 1 and 2!
I can work around this issue just by quitting Cura altogether and reloading the models involved, but it can be really annoying when you’ve got a couple models on the platform and they’ve been scaled, etc. I’m using Cura Lulzbot Edition 19.12 on a Mac.
