I keep getting the dreaded error 9 gcode lockout. I’ve searched the forums and read all the different posts about homing, shock error, etc. I’ve tried all the different solutions and none have made any difference.
I’ve also tried completely rebuilding my image, transferring it in as an svg, etc. My thinking was that maybe the image was a little too detailed (suspected this wasn’t the case but what the heck). This is just a blueprint outline of a tank with some text in it - 2 layers,
Sometimes the burn gets farther than other times but it always ends before it is complete.
Other things burn just fine. The laser chassis isn’t moving, if it were then other burns would fail.

      The error message is a bit unusual.
After the Shock detection message it looks like the laser is reconnecting which is when the error:9 is appearing.
Does the error:9 always follow the Shock detection?
In any case, if you are trying to laser a line drawing of that complexity at 20,000 mm/min you’re going to have a bad time. You’re likely around 2 orders of magnitude too fast for something like that. I’d suggest reducing speed to around 200 mm/min and testing behavior. Does it work in that case? Then you could empirically try increasing speed to see at what point you get the error and at what point the quality is compromised.
If that doesn’t resolve it, can you check the value of GRBL config $603? If you’re not sure about this then run ?? command in Console and return the output.
