before adding 1 frame the construct is still able to move forward and theres nothing infront
You have either reached 1000 blocks ( that includes frames and all block that they move with them ) or the frame you add interferes with the movement ( either touching something that cant be moved (keep in mind frames are sticky and will try to move evething they touch on any of their sides) or interefing with something else ). Just increase the linksize in the configuration file. If it moves after that, the problem was the size.
If size is the problem you can indeed split the construction in multiple parts that move seperately by different motors if for some reason you dont want to change the linksize.
As for the challenge, can we expect a fix for the E network interaction with frames or should we just use the existing workarounds?
I know how to build the Solar-SPAMatron, with moving IC2 machines with the current version, but frankly the workaround to supplying the Mass Fabricator with power after moving is rediculous.
