It is supposed to hit the back switch and then slowly come forward until it is released.
Make sure you are testing with a fully built system so everything is triggered properly. When doing it by hand it won't be the exact same as the platen moving like it is supposed to.
You really think that can be the problem of motor trembling? I am also testing this wiring and have the same problem. You know it does not matter if platen or finger pushes limit switch I think. It should just stop, not talking about platen returning to the front when there is short delay while platen unclick limit switch.
