Adjusting maxvel stops my routine was created by JetForMe
I'm trying to write a g-code subroutine to surface my router table. I've attached the file. I'm running into all sorts of weird issues, but the current one is that if I adjust the Max Velocity while it's running, it just stops with wait_command() returning 1.
I'm calling it with this:
I really struggle to understand why calling a subroutine is so different from executing a loaded g-code file.
I'm calling it with this:
def surfaceTable(self,widget,data=None):
print("surfaceTable called")
if mdiOK():
saveMode = sStat.task_mode
saveCoordinates = sStat.g5x_index
print("Current coordinate system: ", saveCoordinates)
sCommand.mode(linuxcnc.MODE_MDI)
sCommand.wait_complete()
sCommand.mdi("o<surface> call")
result = sCommand.wait_complete(10 * 60)
print(f"surface call wait result: {result}")
sCommand.mode(saveMode)
print("surfaceTable finished")I really struggle to understand why calling a subroutine is so different from executing a loaded g-code file.

Wait_complete monitors linuxcnc status for the current message serial number.
It only checks if the current serial number is _past_ the commanded message serial number.
My educated guess is that since adjusting the maxvelocity sends more commands, the serial number gets changed and the check passes, even though it's the max velocity not the MDI that finished.
Using MDI programmatically is very difficult.

I would try to use custom Mcodes/ subroutines directly and avoid using the python mdi command.

Can you elaborate on how to do that? I'm invoking these from a VCP, buttons bound to Python code.I would try to use custom Mcodes/ subroutines directly and avoid using the python mdi command.

Linuxcnc has buttons for GTK3 and PyQt5 that can be connected to [HALUI] MDI_COMMANDS in hal:
linuxcnc.org/docs/stable/html/gui/halui.html#_mdi_2
www.forum.linuxcnc.org/38-general-linuxc...halui-section#307456
For example panels see:
configs/sim/axis/gladevcp/
configs/sim/axis/qtvcp/
and others.
[edit]
If you are not using any of the above libraries you can also create hal pins through the python halmodule:
