While this isn't something you can add remotely, it's an addon that would work. Install a solenoid "kicker" that can be triggered by an output controlled by LCNC. Then you could send the control computer a command to kick the slide off the limit switch so it can be re-homed - assuming that getti

In this remote configuration, at the moment I do not have access to the graphical display. Is there a way to alter the configuration so I can start up from the command line without a GUI interface? For most operations, all I'll need is the emcrsh interface. On 5/9/2013 5:04 PM, Norton Allen wrote:

My home and limit switches are separate. The limits (at both ends of all axes) are wires in series and drive the hardware interlock. One axis fault = they ALL stop. The home is its own switch and not super close to the limit sw. Did it fault while homing or in normal operation? On Thu, May

Depends on the machine. The factory limits on my supermax signal the controller AND also opens a contactor for the drives. You can override the input to the control (now EMC) all you like but it still doesn't bring the drives back up. You have to mechanically move off the limits (luckily they le

I have a remote device (~3000 miles away) with a single linear axis (lead screw) that is currently on the limit switch near the home position. I have access to the emcrsh interface. Being on the limit apparently turns the machine off. I know that in theory I should be able to override limits in ord
