I was doing a speed tower that changes every 5mm in height. The tower covers 40mm/s to 100mm/s, so I made 11 processes to change the speed from 45mm/s to 100mm/s. I selected "Prepare to print" > "Continuous Printing" > "OK" and the software crashes around 50%.
Well, while I was writing this to give a better description, I found a work around. If I don't have all the processes selected within the Process column (I would have Zone 1 selected only) then selecting 'Prepare to Print' would open the process window where I would then select all process zones. This will cause the software to crash, you must have all processes selected before and after.
I was following the instructions here: https://www.simplify3d.com/resources/ar ... f-a-model/
where it doesn't call this out, so I will assume its a bug?
