Hello everybody.
i'm attempt to install the 4th axis on my delta, for manage the weight of the two extruder.
at the moment the two motor that move the 4th axis are connected in parallel and plugged on the 1st driver connector of the duex5.
they work flawless , but they do what they want (my fault for sure)
here we are. i have some issue with the configuration. i've followed the tutorial for the 4th axis installation but it dont move toghether with the z axis from the dashboard, and neither with x and y (from the dashboard as well)
i have no endstop on the 4th tower, i've configured it using the stall guard, and it works. but something strange happen (in addiction)
when i start the homing, i have two passes, the first one a bit rapidly, then goes down and then another zero
ok. at the first pass the 4th axis (u5) won't go to zero. it came in the second pass.
so...some problem during homing, and wont to follow the effector in the movement (i suppose it should do it on the dashboard as well)
hope you can help me. i'm spending days and maybe i cannot see some huge and basic error.
here's my configurations
