Hello again!
My suspicion was correct, I found that if you connect motors to X11, X12 and X13 ports on 6-axis drive unit (inside DM3 in my case), you should use templates for M1DM3, M3DM3, M5DM3 accordingly.
Very strange logic, but it works
Hello Dimak444
Can you explain a little more about how you solved it? I'm still having the same problem.
many thanks
