Replying to my own post, following some very good instructions from a person in this forum , I manage to get the material customized to my requirements.
Now somehow there is no way I can print PLA without raft, the priming line is perfect and sticks very well, but as soon as the actual print starts the head to bed distance increases to a value almost double the card size , I tried ofsets but I do not understand how to use them…
any help is very welcome …please
