K8600 firmware chrashes using simplify 3D

I purchased simplify 3d to improve printing results(see forum). I set the profile and generate a file. When starting printing the firmware crashes … resetting the printer.
With cura ans Slic3r everything works fine.
Any Idea what happens and how to be able to recover this issue ?
A firmware update on K8600 seems not to work (see other posts in this forum)
Best regards

I would like to know this as well.

I want to start using Simplify3D with my K8600, as it has a lot more options as the standard Repetier Host with Cura.

Hi i know its an old topic but check your set speed max is about 30mm/s
I tried cura wich was set to 60 the moment it was moving it resets.
