The error is likely in another file that is being called by config.g

There is already a feature request to show the name of the macro in error messages
https://github.com/Duet3D/RepRapFirmware/issues/761

T3P3 created this issue in Duet3D/RepRapFirmware

open Report filename in error messages #761

@GratefulAbyss37
What you are seeing is a warning, not an error.
Somewhere, either in your config.g or in another file, there is a call to G29 which loads a bed height compensation map.
https://docs.duet3d.com/en/User_manual/Reference/Gcodes#g29-mesh-bed-probe

This should only be done AFTER homing the Z axis ( G28 ) so that a zero reference point has been properly established.

Search your files and remove the G29.

In general, when asking for help you should post your config.g and any other files which might relate such as homeall.g and homez.g

@Macgyver
It's a pity M587.2 doesn't have an option to return an array with just SSID names.
Then you could cut out incorrect entries.

Unfortunately it only gives a text output full of unnecessary information (for a macro) or a json return

Aside from the previous comments, a few things.

If you want to use variables in the M291 then use something like

var choice= [-1,-1]
var options1 = ["A","B","C","D"]
M291 K{options1} .....
if input >=0 
   set var.choice[0]= input

Note that input is the returned index so it is zero based
So it will be 0,1,2,3 or cancelled
Depending on firmware version, the result of a cancellation or timeout is different so you'll need to consider that

I would put your two choices into another array rather than a number as it will be easier to do your compatibility tests.

I would also work out my choice arrays so that after choosing the first, the M291 on the second only presents valid choices

Lastly, you can't use line breaks and mixed comments in your Boolean OR logic like that
You'd need to change it to
if
blah
elif
blah blah

@St-Taw
The mesh offset is typically set to taper off as the Z height increases.

This is set by M376 in config.g (usually)

https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m376-set-bed-compensation-taper

Any baby steps applied will also result in a difference between user and machine positions.

Last stop height reports the Z height when the sensor triggered. No mesh offset is applied. However for it to be accurate, you must calibrate it.
https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_testing

@SonnyD1
I'm afraid I know nothing about scanning probes, so I'll leave that for someone else

@SonnyD1

You have M557 commented out in your config so I'm guessing it's (the probe grid) undefined when you access the object model variables in your home.z

; Mesh Bed Compensation
;M557 X25:175 Y25:175 S40:40                                     ; define grid for mesh bed compensation

Try echoing the variable positions to confirm

; home Z
var xCenter = move.compensation.probeGrid.mins[0] + (move.compensation.probeGrid.maxs[0] - move.compensation.probeGrid.mins[0]) / 2 - sensors.probes[0].offsets[0]
var yCenter = move.compensation.probeGrid.mins[1] + (move.compensation.probeGrid.maxs[1] - move.compensation.probeGrid.mins[1]) / 2 - sensors.probes[0].offsets[1]

echo "x position " , var.Center
echo "y position " , var.yCenter

G1 X{var.xCenter} Y{var.yCenter} F6000 ; go to bed centre

@dc42 said in metacode rread-only variables:

@OwenD using 'const' wouldn't affect the memory usage.

Ah well.
In that case I can dress in either direction.
Can't hurt anyone and may help some.

@dc42 said in metacode rread-only variables:

maybe "global const" could create a global constant and "const" by itself create a local constant.

This is probably closest to convention with most languages.
If it resulted in lower memory usage then I'd vote for it.

@Surgikill said in Triggering 'Load Filament' prompt with a macro:

@dc42 Yes, I am doing that now. However, I want the prompt to contain options that are dynamically created based on the content of "0:/filaments". I don't want to update the prompt every time I add a filament, or modify the name of a filament. Just like how DWC creates the prompt when pressing the 'Load Filament' button.

At present RRF doesn't have any string handling routines and no way of extracting file information or file lists.
The best you can do is use the object model item
move.extruders[0].filament
which will show the currently loaded filament (or null)
I ran into a similar issue trying to create a filament change macro to use from PanelDue as my printer is in the shed and my computer inside.
I had to manually list all the filament types I use in an array.

This is what I came up with.
It may (or may not) help in your case.

@Tinchus

From the docs..,
The H parameter defines the Z probe dive height, which is the height above the trigger height from which probing starts. The default is 3mm or 5mm depending on firmware version. You may wish to increase it during initial calibration. When using mesh bed compensation or running G30 commands with specified XY coordinates (for example from the bed.g file), the firmware moves the Z probe to this height above where it expects the bed to be before commencing probing. The maximum depth of probing from this position is twice the dive height.

I think you'll find on straight G30 Z home, the dive height is ignored as the height is unknown.
Otherwise you would never be able to home from any height.
About the best you can do is check for typical errors before you start using the object model.

I use this macro which is called before any Z homing or bed leveling

check BL Touch
var probeOK = true
if sensors.probes[0].value[0]=1000 ; if probe is in error state
	set var.probeOK = false
	echo "Probe in error state- resetting"
	M280 P0 S160 ; reset BL Touch
	G4 S0.5
if state.gpOut[0].pwm < 0.05
	set var.probeOK = false
	echo "Probe is already deployed - retracting"
	M98 P"0:/sys/retractprobe.g"
	G4 S0.5

if sensors.endstops[2].triggered
	set var.probeOK = false
	echo "Probe is already triggered - resetting"
	M280 P0 S160 ; reset BL Touch
	G4 S0.5

I also use this check in my homeall.g to cancel the print if any errors occur during homing
Any successful command should return a value of 0

G30               ; home Z by probing the bed
if result !=0
	abort "Print cancelled due to probe error"

Outside that, you'd have to have a secondary switch, pressure sensor or similar attached I'd think.

@dc42
I have attached the config.g and the other macros called.
Also the filament config.g as that is where I am setting pressure advance if that's relevant.

config(ABS).g
set_max_speeds.g
config.g
setInputShaping.g
config-override.g
daemon.g

@curieos
I've found that if you have much going on in daemon.g the any "songs" will be very erratic in behaviour.
I have a variable at the start of daemon.g which allows me to temporarily skip it, which helps, but doesn't make it perfect.
I suspect there's so much going on in the firmware now that's taking up cycles that M300 will not be useful for much more than single tones.

Just had this error occur again.
It's not 100% repeatable as I've had it fail twice on the same print (with two firmware versions) but print successfully the next try.
Both failures were 5-6 hours into the print.

EDIT
One difference this time is that when I shut the power off, no resurrect.g was created, so it looks like I've lost this print.

Now the print is finished I have just tested sending G94 from the command line and it gives no errors, so I've answered that half of the question.

Whilst recovering from a power outage I got an error message saying something like
"Missing or bad parameter"
Whilst searching for a possible cause I noticed that resurrect.g contains G94, which according to the docs is CNC specific

G94: Feed Rate Mode (Units per Minute)
CNC specific. Supported from firmware version 3.5
Parameters
No additional parameters

Should this command be there and would it cause that error in FFF mode?

EDIT:
Of interest to anyone testing , I think I've saved the print by turning off the power and recovering from power failure.

@amimafe
The firmware essentially already does that.
You just need to monitor your extruder and trigger a pause when it's not extruding.
As you've given no details on what you're "extruding" or how you're doing it, it's impossible for anyone to offer any more than equally vague answers.

There is no facility in RRF currently to reverse along previous moves to a point.
That would be the domain of external software which streams gcode to the duet in individual strings.
It is relatively common in plasma cnc cutting controllers for example, but there is no extrusion at play there.
You can use the object model to get the current file position in bytes, but I don't see any way in a macro to extract lines from the job file and pass them as movement commands.
You also have the issue of having to work out what to do with the extruder moves. Do you want the extruder reversing at each move?
What about I/O's, fan or heater commands?
Far better to identify a fault and pause immediately as is already implemented.

@cichaczech

The list of object model values is at

https://github.com/Duet3D/RepRapFirmware/wiki/Object-Model-Documentation

The list of meta commands is at

https://docs.duet3d.com/en/User_manual/Reference/Gcode_meta_commands

You should be able to use state.machineMode in the object model.
