Hi,

is there a way to execute a nc-file or python script on startup of Gmoccapy after the gui is loaded?

Thanks

Matthias

It should be possible, for nc file just adding this to the "display" section in the ini file should work:
open_file = name_of_the_file_to_open.ngc
It works with Axis GUI so it should with Gmoccapy.
Should also be possible for python, but i'll leave that to more experienced members here.

To execute a file, machine must be homed. After homing the last axis, for this axis in the hal file, at
'net n-is-homed halui.joint.n.is-homed' add: halui.mdi-command-nn

In .ini file
[HALUI]
MDI_COMMAND = Mnnn

In the executable Mnnn file your code
(n for axis and numbers)

To hook only one axis homed, it may cause an error, if not all axis are homed. So I would recommend to hook them to something like all_homed, that is the way gmoccapy reloads the tool on start up, Getting the all homed state, gmoccapy executes an MDI Command

Hi,

Thanks for the hint.

My Ini File:
[HALUI]
MDI_COMMAND = o<startupcheck> call

My Postgui.hal:
net allhomed => halui.mdi-command-00

"allhomed" is calculated from all homeswitches.

But there is one problem left. Since my machine is still moving to the "home" Positionig after homing was done, there is an Error Msg "Change to MDI not possible" Is there a way to place an delay?

thanks

Have you tried to include a G4 P5 in your file?

Use an and2 using all-homed and motion.motion-type = 0?

That last condition will be slightly painful, as it's an s32 and needs to be convereted to float to use wcomp to test for zero.

Hi,

i've done it.

in my hal-file

# -- NC-script on Startup Check with debounce --
loadrt debounce cfg=32,10,1
addf debounce.2 servo-thread
setp debounce.2.delay 1000
net all-homed => debounce.0.0.in
net mdi-cmd-startup <= debounce.0.0.out => halui.mdi-command-00


Thanks

Hmmm that may also work with timedelay

net mdi-cmd-startup <= debounce.0.0.out => halui.mdi-command-00


Is there a native gmoccapy pin which needs to be connected to the "all-homed" signal, or is it created by using a few and2 components combining all "joint.N.is-homed" pins to create an "all-homed" pin?

Thanks.
