Help with Homing on a RDC6445G Controller

[Aaron Finkel]

I recently upgraded my k40 with a RDC6445G controller and am still having some issues, namely in regards to homing. The laser will slowly go towards the bottom right when turned on and calls it's coordinates x:10000 and y:10000 on start up. I have upper left selected in RDWorks, but that seems to do nothing. What I want to happen is for it to act like my old Nano did, where it goes to the upper left until it hits the limit switches and defines that point as x:0 y:0. I imagine I have to do stuff mostly within the controller itself, but I can't seem to find what I'm looking for.

You need to reverse the rotation of the stepper motors.
You can do this within the controller or the stepper wiring.

I don't think thats the problem. the jog both on the controller and RDWorks goes in the right direction

1st. Did you tell RDWorks the correct homing corner when you installed it?

2nd. I believe in the vendor file there is a separate selection for limiter polarity. I have no idea if this is for the motor, or if it swaps the switch sensitivity from NO to NC, but it would be worth playing with.

I'd have to go and fire up the controller itself to see what there is there for settings. I dearly wish Ruida had a simulator.

There is definitely a setting in the software and on the controller itself. I know this because I messed mine up.

I’m attaching 2 photos one is the controller screen option I think you are looking for, and the second is the RDWorks Manual page that contains laser head starting point setting.
