My bot is now working with my MK5 installed. Doesn't took me too much time to build and it works right on the first time. OK, some adjustments need to be done but i was able to print a 15MM cube and a whistle :-)
I also updated firmwares with latest one from ReplicatorG 20 and for the first time I was able to print raftless without any adjustment. It was not perfect but far better than before.
