Not the behavior I want from an Emergency Stop. If an item is connected to the Normally Closed side of the relay, resetting the microcontroller is going to turn that item back on. These relays have Normally Open and Normally Closed connections, similar to the microswitches. I’ve got spindle control and other relay-controlled connections also connected to the microcontroller. I wouldn’t trust any of them to truly stop all activity if the machine were misbehaving and/or creating a dangerous situation. Grbl supports cycle start, cycle pause, cycle cancel, and e-stop connections through the CNC Shield that I’m using. I don’t trust the micro-switch “E-Stop” connections on these boards that just reset the microcontroller to protect me in case of a real emergency. And, remember that you’ll be reaching for this when things aren’t going well - you’re likely to be flustered, frustrated, or just plain terrified. Test it, and don’t trust assumptions about how things are supposed to behave. Make sure that your e-stop configuration meets your needs and risk tolerance. This is a bit of a soapbox issue for me.)

(you do it after connecting to CNC xPRO v5 thought ACCESS POINT, wifi signal which controler is making on his own and update firmware through WebUI, password for connection is 12345678). So after changing the firmware to NC type everything works as it should. I couldn’t do the thing becase I didn’t know that the firmware loaded on the hardware was the NO - so the safety bytton needed to be pressed - if wasn’t machine would think that door are open.īut I want to use this “emergency button” to kill the machine if something goes wrong while operating and to be able to use machine right from the start after opening CNCjs. So generally you have to options of the safety switch: Spark-Concepts/xPro-V5/tree/main/Firmware You have right now few firmwares to choose - about 4 - You can find it on Github. It’s with the configuration of the Hardware - CNC xPRO v5 controler. I will leave the solution to my problem for someone else who might struggle.
