Yup. I could not forsee a situation where M3 would be running, the collet (vise) is open, and I'd need to hit the estop.
right right ok and i wish this was the case for me too, since this is the easiest solution.
If you want the vise ENTIRELY independent of MACH, a simple ON/OFF switch would be the easiest, imo. Why do you need some sort of sw to control it anyway ?
Yes i agree that would be very easy but I don't want it independant of mach3 though, i want it independent of ESTOP signal.
The main goal is full automation. The vise is sort of the first step. I am cutting very often the same part, like 100's at a time so i am working on a feeder/robotic arm to feed pieces into the vise, but the vise first needs to work, so that is the step we are at now.
Originally i had bought a Modbus over etehrnet relay board which i think would avoid this since i doubt estop sends modbus coil register signals (i hope not anyways haha). But even though i could get it to work with the modbus test window in mach3, i could not get it to work with vb script or brains, even after reading some threads which sounded like people had similar issues, these solutions did not workout for me. So instead now i moved the goalpost a bit and am going direct onto my controller card which unfortunately now seems to be affected by the estop signal, although from research this seems normal, not an issue with the card, it is what "should" happen etc...
anyways its a classic case of not doing enough research before buying some parts and just assuming it will work out, but ya im just trying to make something work with what i have on hand atm. it does almost work ahah.
here is a short video if you want to see a test of the vise opening/closing for fun.
