Print Error on all jobs
-
I started getting a print error which i cannot locate the source. i've been making some minor changes to my config.g and IDEX pre, post, free files. suddenly i cannot start a print because the print job immediately errors out with the following info:
4/15/2023, 11:10:34 AM M32 "0:/gcodes/chip_0.2mm_PLA_41m.gcode" File 0:/gcodes/chip_0.2mm_PLA_41m.gcode selected for printing Error: in file macro line 129 column 25: meta command: reached null object before end of selector string Cancelled printing file 0:/gcodes/chip_0.2mm_PLA_41m.gcode, print time was 0h 0m 4/15/2023, 11:10:09 AM Error: in file macro line 129 column 25: meta command: reached null object before end of selector string Cancelled printing file 0:/gcodes/Dual_Color Cali-Cube - V2 - S2_0.2mm_PLA_1h34m.gcode, print time was 0h 0m 4/15/2023, 11:10:07 AM Macro retractprobe.g complete 4/15/2023, 11:09:52 AM Macro deployprobe.g completeif i reboot the printer it seems like i can make 1 successful print of any job. but then going forward all print jobs fail with the same error shown above. only a reboot seems to fix the issue temporarily.
I dont know which macro line 129 is referring to because even if i print any random print job created from weeks ago i still get the same line 129 error which makes no sense. it doesnt seem to relate to the actual print job file.
any help is appreciated.
here is my config file

@RogerPodacter i have recently added a new GPIO micro switch which i plan to experiment with. but when i remove the switch i continue to get the same error.
-
I dont know which macro line 129 is referring to
Just being curious: how many macro files of 129 or more lines populate your /sys/ or /macros/ directories?
-
@RogerPodacter said in Print Error on all jobs:
Error: in file macro line 129 column 25: meta command: reached null object before end of selector string
The error is (likely) coming from another macro that is being called at the start of the print (homing, leveling etc)
You have some incorrect meta code.
If you put an echo such asecho "entering start.g"andecho "finished start.g"
in your files it will help narrow down where it is.
Could also be daemon.g if you run that.Your new code for the switch is of course the first suspect.
For example something likeif sensors.gpIn[5].value = 1would throw that error if there was no sensor configured on pin #5 -
@OwenD yes my new code is exactly something like "if sensors.gpIn[0].value == 0". but while troubleshooting i have removed all new code to try and isolate the cause, but i continue to get the same error somehow.
this is the new line i added in my config for the switch:

-
@OwenD part of my code changes include adding a new Tool 3 which combines 2 extruder motors together, almost like Duplicate mode on an IDEX. i did not alter my daemon.g, but perhaps somehow now my daemon LED code is looking for additional heaters that dont exist. attached is a macro called from my daemon.g and it is the only macro larger than 129 lines of code.
-
@RogerPodacter i was able to correct my issue. i dont quite understand why, but the LED code is called at the start of my prints. and it looks for # of tools. once i added my extra tool to the start gcode, the error no longer happens. the micro switch is part of the new tool but i guess directly wasnt causing the error...?
-
@RogerPodacter
I don't see where you call the macro to set the led by temp.
There are several possible causes, all of which relate to trying to access a value from an undefined objectYou are looping the X number of tools and checking the heater values.
If the tools weren't created in numerical order then using iterations to identify a tool or heater would cause an error
e.g if you have tool0 and tool3 defined but no tool2
If one of the tools did not yet have a heater defined it would cause an error
And if the switch wasn't defined you'd get an errorDaemon.g may start running before config.g finishes, so if the errors appear at startup you may need a variable to exit the daemon until config.g finishes setting everything up.
state.upTime would sufficeIt seems like earlier versions of RRF were simply ignoring errors at times, so what "has always worked" could just be in unreported issue that's been there for some time.
