Hi guys I have got my cnc mill control panel working ok now just have some questions about the best and proper way to implement the safety E stop circuit and initial power on of the cnc machine
I did some searching of course, but thought I would ask here and see what the latest and best way is. searching on the forum, some of the info was a little dated. so if anyone has any advice I would most appreciate it. I saw on Youtube what samco(skunkworks) (I think his name is chris Radek) has done. And this is pretty much what I want i think. I think this should happen when the E stop is pushed. Cut control power to all servos and main spindle VFD. (I think I may need to just send a E stop signal to the VFD as it doesn't have control power that I can cut.) It seems a big extreme to cut main power and possible damage the vfd with loose high voltages etc. It should tell linuxcnc that the E stop is pushed. I need to set up a latching relay somehow to make sure the E stop doesn't turn back on until I turn it on within linuxcnc. Servo Power on setup. I want a Button I can push which enables all the servo drives( there is a Servo on pin on the servo drives) and then also enable the vfd however I need to do that. This is separate to the E stop. Currently I am only using step and direction control and I am wondering how hard it will be to tie in the encoder signals to linux cnc with another mesa card. otherwise when i push the E stop I will have to re home the machine. anyway please sing out with any feedback you have and ideas. I would love to get some ideas here from those who have done this all before. I am using a mesa 5i25 7i76 combo. And I have all sorts of contactors etc. Regards Andrew <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
