OK, here is my solution (actually a work-around) to the re-boot problem when using Simplify 3D. I have tested it about 50 times and have not had it reboot once. The problem, as several users have mentioned, is that when using S3D on large complicated files, the system may or may not reboot during the upload process. The larger the file, the more likely it is to reboot. When tracking the upload process, I find that it does not crash at the same point in the file. Sometimes it is soon, sometimes it is later. I am not sure what is going on.
Also, noteworthy, is that XYZware never (knock on wood) crashes during the upload. My solution is to generate the *.gcocde in S3D and then print it with XYZware. If you try to use the straight S3D file, XYZware will give you a printer mismatch error. The way around this is to add a HEADER to the *.gcode file that will set XYZware on the right track. The HEADER that I use is as follows...
; filename = composition.3w
; machine = daVinciF10
; extruder = 1
G21 ; set units to millimeters
You can use a text editor to add these four lines at the top of the S3D gcode, then save it, load it into your XYZware and print your object.
I have a 1.1.J DaVinci XYZ printer and I have avoided uploading any recent upgrades from DaVinci. I do believe they are trying to sabotage any 3rd-party contributions.
Some of you that are having trouble with rebooting on large files, try this work-around, and let us know how it works.
