So I have been tasked at my job to do this to the laser, I know little about laser cutters or circuits in general I’m more mechanically. But what it runs down to is the auto feed belt needs to be driven by a foot pedal (for manual control) and be able to be switched back over to the system control using a switch. The controller in the machine is the RDC644S-B (EC). Now is it possible to split the stepper wires connect it to a switch route it to an Arduino and then the foot peddle and on the other side of the switch route it to to the normal wiring and have it still function normally. Or is the general input port CN2 used for something like that it says foot switch but I don’t know where to go from there is there a way to program it to do that with the controller?
There is probably a way to do this with a microprocessor if you can program it.
The speeds on most machines is not that great compared to these low cost fast processors …
I don’t know your specific instance, but the Ruida will ‘lose’ it’s position on the ‘belt’ doing this… if that matters.
This is from the 644x Ruida users manual … the FootSW input is specified as follows.
Input port of foot switch. The connection method is: when the pedal is stepped down, the low-level signal will be inputted to this port; when the pedal is released, the port will be disconnected or the high-level signal can be inputted to this port; when the stepped-down pedal is held for not less than 100 ms, if the machine lies idle, it can be started for work; if the machine is in the working state, the work will be suspended; of the machine is in the suspension, the work will be restarted, that is to say, the function of the pedal switch is the same as that of the “Start/Pause” key. If the interval time to the first stepping-down of the pedal should be less than 100ms when the pedal is stepped down once again, the second stepping-down of the pedal will be considered invalid by the mainboard.
