Every time I start or reset my controller (Ruida 6445G) It homes, goes to the last position and runs the last program in memory. Has anyone seen this behavior? It just started doing it…
It should not just start running on startup. Could be dangerous if the laser was on…
There’s a connection on the controller labeled '‘FootSW’ (on the 6442 series the connector is labeled CN2). That connection is used to start and pause jobs using a foot switch. If that pin were being shorted to ground somehow, that could trigger a file to start.
I have never heard of this happening before, but this is a possible way I can imagine it could happen.
I’m assuming it was in error, and possibly meant to be wired through the ‘door’ input, which would halt the machine. Those two pins are next to each other.
The e-stop being wired to the foot switch would kill a running job, but isn’t what I would consider a true e-stop (as the foot switch is a controller command). An e-stop should be a hard stop / mains disconnect kill.
You never know what could go wrong. A running job isn’t the only thing an e-stop protects. For example, the other day I was auto focusing and my focus block moved slightly and I was headed for a crash. E stop to the rescue. I’m not even sure if the foot switch would stop auto focus.
