Hello All, Does anyone have any additional troubleshooting steps for f/w flash failures when trying to wire a normally open e-stop to the Door port on a BlackBox? Using the Normally Open side of the e-stop only. The switch and wiring test ok for continuity when extended, no continuity when depressed. When attempting to flash, I get the generic Grbl controller not found error. Tried flashing with the wiring connected and w/out. Flashing back to default works fine once the e-stop is disconnected. Thank you.
Not advisable. In an emergency, hitting that, will merely pause the machine from moving. But what constitutes all possible emergencies? What if router catches on fire psu catches fire you spilled coffee and its fast running toward the PSU on the desk there loose hanging wire start electrocuting something/someone etc etc with continually worse outcomes You want an E-Stop to CUT POWER! Thats almost non negotiable. Cut the mains power, before the power strip, so everything turns off in an emergency In addition, just a note Normally Open = no continuity when "open", ie not pressed. You're second part "no continuity when depressed" describes normally closed (thus open when the switch is pressed as pressed is not the normal state)
