Hi, Halkintool
If your statement is, (I tried pushing the limit switch in while the machine was homing and i get the "limit trigger switch error").
Then your Home Switch's Setting are Incorrect, On the Diagnostic Screen you can test them, The Home Led's should turn On & Off with the same axis Limit Switch.
Let us now what you see on the diag. screen Hear are some Pic's.
Edit: Enabled, Actives should be the same for Limit's & Home SW's And none should be Emulated
Thanks, Chip
