Alarm:2 after toolchange

[Klippert]

Hello,

I've now had fairly long (1-3hour) programs running with 4-6 toolchanges, and it gennerally works really well.

Twice i've had it stop after a toolchange with alarm:2.
I've had to reset the machine, home, reload, remove sections done, and restart, after which it runs the program smoothly.

It happens in the same situation both times, the tool is changed, TPW'd, and cycle is started and the machine moves up, to the first x,y coordinate, and then stops.

At first I thought it was because the tool was long and the height i tried to lift to was outside the machines range, but now it also happended with a very short tool.

Any suggestions on how to fix it would be most welcome.

Best regards
Kristoffer

Alarm 2 is soft limits exceeded. If this is happening randomly then it could be hard to track down.

What is your $341 setting?
Is cycle start issued with sender button or button (switch) connected to the controller?

The Pause function only stops moving, the „safety Door“ stops the Spindle and drives the Endmill out of the Workpiece.
So both functions have their usecase :-)

Is there a documentation of the parameters 56-59? - i'm a bit confused on the pull-out distance and the parking target.

definitely a usefull feature :)

$56 Parking pull-out distance - the distance the cutter travels at the speed set in $57 Parking pull-out rate after the safty door is triggered.
The spindle is then switched off and moves at the speed from $59, Parking fast rate, to the set height from $58 Parking target (note: machine position).
After pressing start, everything takes place in reverse order and the milling job continues.

is there a grbl-hal manual somewhere?

There are some information in the grblHAL Wiki, mainly supplements to the legacy Grbl Wiki. The legacy wiki should be pulled in?
