Touch plate error

Hello, When running the touch plate routine I'm getting the error message "Parameter file name not found" and the tool table file isn't getting updated with the new length.

SilverDragon
Linuxcnc 2.9 from buildbot.

thanks

Andy, thanks for the reply. Here is what I think you were asking for but I'm not sure what file is missing? Or could it be a missing parameter and not a file?

I get that message alot when linuxcnc aborts -I haven't trued to track it done yet.
The parameter file name is fine (in my case - in master)

Andy, yes the file linuxcnc.var does exist in the machine config folder. I created another machine with pncconf as a test and it is coming up with the same error as well?

The error happens during the running of the touch plate routine. It is after the measurement step and what seems to be a missing formula variable, missing file or a writing error. Not sure? Any help would be appreciated.

thanks

I searched and It seemed built in so I downloaded the source code to see. Here is what seems to be the code located in qtdragon_handler.py.

def touchoff(self, selector):
if selector == 'touchplate':
z_offset = float(self.w.lineEdit_touch_height.text())
elif selector == 'sensor':
z_offset = float(self.w.lineEdit_sensor_height.text()) - float(self.w.lineEdit_work_height.text())
else:
self.add_status("Unknown touchoff routine specified")
return
self.add_status("Touchoff to {} started".format(selector))
max_probe = self.w.lineEdit_max_probe.text()
search_vel = self.w.lineEdit_search_vel.text()
probe_vel = self.w.lineEdit_probe_vel.text()
ACTION.CALL_MDI("G21 G49")
ACTION.CALL_MDI("G10 L20 P0 Z0")
ACTION.CALL_MDI("G91")
command = "G38.2 Z-{} F{}".format(max_probe, search_vel)
if ACTION.CALL_MDI_WAIT(command, 10) == -1:
ACTION.CALL_MDI("G90")
return
if ACTION.CALL_MDI_WAIT("G1 Z4.0"):
ACTION.CALL_MDI("G90")
return
ACTION.CALL_MDI("G4 P0.5")
command = "G38.2 Z-4.4 F{}".format(probe_vel)
if ACTION.CALL_MDI_WAIT(command, 10) == -1:
ACTION.CALL_MDI("G90")
return
command = "G10 L20 P0 Z{}".format(z_offset)
ACTION.CALL_MDI_WAIT(command)
command = "G1 Z10 F{}".format(search_vel)
ACTION.CALL_MDI_WAIT(command)
ACTION.CALL_MDI("G90")

I can get this error message by aborting running code.
but not in all qt screens.

with print statements I can see the cc code is getting the right ini/param file.
This is a mystery.
