Hi Ynneb,
According to the manual I have pin 1 and 2 and pin 3 and 4 connected to get the drives in SPI mode. I think I had a bad connection( although I used the same cable with my geckos) between the motherboard and the printerport. The next day I re-connected everything and the whole system was working.
Thanks anyway,
Frank
PS: Now and then I have some quirks in my Y and Z motors. Today I gonna make some new encoder connections
