To check if the limits cables were broken or not I knew the problem was related to the Y and A axis limits because the problem happens only when I try to home these 2 axis. So I disconnected first the A axis limits cable at both ends and installed a temporary brand new cable. Then I try to home the Y axis and the same message comes up. Did the same for the Y axis and the results was the same. So the message “Limits switch triggered” is not related to broken cables.

If someone can answer my previous post about what the M4++Limits / M4Home message refers to I may understand more and perhaps be able to solve the problem

Thanks
