Spindle immediately turns off on error

dc42

Stopping all commands in the buffer could lead to a positioning error. Alternatively, I can have the spindle kept on until the buffer is empty. Would that be acceptable?

The main reason - safe machining, and catch all inconsistent operations

Yes, so try to catch it in CAM simulation instead of on the Duet? I.e. avoiding it all together.

Or run it on the Duet in simulation mode?

Yes, this will solve the problem of a broken cutter due to movement with the spindle off.

But, Is it possible to catch the error event to run a script to handle the situation? Is it possible to determine that the last job failed? I would like to determine (inside trigger handler) whether it was done manually (canceled) or as a result of an error ? The trigger fires when machine state is idle.

I guess I could add a "last job finish status" value to the object model.

@bearer Cam simulations is OK. Out of bounds of coordinates occurred due to the incorrect WCS (a few mm was insufficient).

@dc42 Good idea! But in order to correctly interpret when it happened (just) or a long time ago, it would be good to either reset this status on request (for example, after processing inside a trigger) or so that the last status has the time of the event, how long ago it happened at the time of its reading. Just for example:

if {job.lastPrintStatus='some failure code'} && {job.lastPrintStatusAge < 10} ; react if it is a 'fresh' event, not older 10 seconds (or a couple seconds  would be enough for process)
     echo "Last recent job failed";

; proposition for event age value
; if this code executes just after error event
echo {job.lastPrintStatusAge} ; will be 0 sec
G4 S1.0
echo {job.lastPrintStatusAge} ; will be 1 sec
G4 S10.0
echo {job.lastPrintStatusAge} ; will be 11 sec

Maybe a parameter to the M453 command to set if it should be affected by an error or not.

@dc42 Hi, David! Any progress ?

Not yet, but it's on the list for possible inclusion in the 3.2 release.
