Got some problems during the electronics part in the upgrade from 1.0 to 2.0!
I'm almost done


The fan doesn't start and I have no power to the opto sensors etc. The axis' doesn't respond. Totally dead. I can connect to it, but that's it.
The wireing on the power supply looks much more different on 1.0 than on the pictures from the manual on 2.0. I think the problem is somewhere with the ground and power cable. In 13.3 it says:
In the old setup, a green wire was soldered to a black wire to finish the loop. I divided this bond to release the green wire and found the purple which was "free" and never used in the old setup. This is probably hoplessly wrong!"Connect green and purple wire.
Green wire functions as an on-off switch for the printer.
The purple wire is the standby power for the logic of the electronics."

Please help,
Thanks in advance,
Markus
