I tried it without all Signs. Only letters.
At the moment i have saved maybe 50 files..
Sometimes it works a few hours and i can do all.
From one second it crash every saving or closing.
I thought it was something with "standby" from windows since i restarted the computer and it works with the same files. But this isn´t it.
It´s very confusing.
And i start again with cura because so i can´t work.
Every change i have to save the factory file with two names, because one file is empty after crash.
I don´t give up easy to find out where are problems. But i don´t find clear context. Only when it crash then it crash at saving or closing and after i used minimun once "prepare to print".
I tried it with the english language. It was the same.
I find if I create a profile for a generic 3d printer (I build printer so this is the norm) S3D works like a charm.
When I load a profile for FF Creator or FF Dreamer which 2 of my customers have... I have no end to the software crashing.
I spoke to some mates online and they have the same sort of issues with Flashforge versions. One guy has found that if he uses the cracked version of 4.0 with the authentication removed, he doesn't ever have this issue. Now I am not saying he is right or wrong... but it might be a clue for the Devs to look into.
He has to create a new downloadable profile on his legal version then export and import to the non.
So my thinking is A. the Authentication is playing a role (doubt it but I'll try wireshark and see)
B. the creating exporting and importing fixes the issues.
