Strange homing sequence

Hi ( Video link of issue at bottom)
I’m upgrading my 80w Chinese laser to a Ruida 6445G controller.

I’m doing a trial setup on my desk using 2 stepper motors and 2 limit switches.
The 2 limit switches are wired normally closed to the controller’s CN4 port between GND and lnt Y- and GND lnt X-

Here is the issue:
Pressing “RESET” on RUIDA controller sends both X and Y axis to search for home limits.
Pressing and holding the Y limit stops the Y motor, but once the X limit is hit, both motors continue in the same direction.

Further, if I release the limit switches during the same cycle, both motors now begin rotating in the opposite direction.

I have experimented with every variation possible in Lightburn’s Machine settings in relation to X and Y axis settings. Any suggestions would be appreciated.

Here is a video of the issue:


You want normally open switches. They just pull the sense line low on contact.

Thank you- Setting the limits to Normally Open did the trick. The homing cycle is now good.
Much appreciated

I’m glad to be of assistance. Looks like you have your work cut out for you. Take care.

You need to mark the problem solved… :wink:
