Title: Gcode should rewind on Estop
Post by: panaceabeachbum on September 17, 2008, 08:36:06 PM
How can I set mach up to automaticly rewind the gcode to the begining when I enter estop?

All the commercial controllers I have used and have on other machinery in my shop, they all revert back to the begining of the gcode file when restarting after estop, they have a start from feature so you can choose the block or line you want to start from if you choose to start somewhere out in the middle .

I rarely am on the cycle screen when running parts and have to go over to the cycle screen to click the rewind button and have broken a number of tools when I forget to hit the rewind button after an estop , I am sure its useful to have the gcode file run from the point where you hit the estop button to some but its not std on most commercial machines and I feel like an old dog sometimes

RT,
If you have an external RESET button, the following works. It rewinds the file when you hit the external reset button.
This works well in simulation.
Use 2 OEM triggers, both assigned to the same pin. 1002 is REWIND and 1021 is RESET.
Cant do it with my small brain. ::)

One other thing...The external RESET button will also put it in E-Stop if it is running. It toggles the function just like the button on screen does. Id use a momentary NO button, active HI. The type of button that is not easily activated inadvertently. A typical START button.
Probably a better way, just thought I'd give it a shot.......between shots.
