The CURA endcoade for Rostock machines needs to be improved. I have, on multiple occasions, ruined freshly printed parts by forgetting to change the endcode.
All you need is a G28 command - that will home the machine. I am running a RostockMAX and it works fine. Here is the endcode i use, i strip out anything that is not required to keep it simple.
M104 S0
M140 S0
G28
M84
This works fine, i do not get the motor creep' you speak of.
Hope this helps, would love to see CURA improved for the Rostock machines in the future.
