This solved the problem.
Thank you a lot

@dc42 and @T3P3Tony
Do you know what the problem is and how this "expected numeric operand" can be avoided/solved?

@dc42, @T3P3Tony and @cosmowave

If there is no "then" like this:

;if tools[0].state="active"
;	then M568 P0 R{tools[0].active}
;	echo "tool 0 (V6) ist active."

;if tools[1].state="active"
;	then M568 P1 R{tools[1].active}
;	echo "tool 1 (Volcano) ist active."
	


var temp0 = {tools[0].active}
var temp1 = {tools[1].active}

if tools[0].state="active"
	M568 P0 R{var.temp0}
	echo "tool 0 (V6) ist active."

if tools[1].state="active"
	M568 P1 R{var.temp1}
	echo "tool 1 (Volcano) ist active."

I still get this back:

M98 P"0:/macros/00_Toolselect_check"
Error: in file macro line 15 column 24: M568: expected numeric operand
tool 0 (V6) ist active.

The error appears in this line:

M568 P0 R{var.temp0}

On:
Board: Duet 2 Ethernet (2Ethernet)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.0beta5+1 (2021-10-28)

@t3p3tony said in multiple filament sensors:

the error messages are in the firmware code - they are not it a user editable text file. You could add a second notice to the user in your filamen-errorX.g

Thanks, then I will leave it as it is.

@phil333 said in multiple filament sensors:

While testing this, I saw that sometimes the pausing of the print needs longer or kind of freezes the printer.
I mean the tool always stops and normally it goes back to its homing position.
But sometimes it stops, needs ~5-15 sec and then goes back.

Try and tie down what part of the gcode file has this issue, the shorter and more reproducible the better.

Does this happen with both tools or just one?

Its hard to say or to determinate which code is doing it, as there seems to be some background (firmware) code to be involved as well.

I think that it happens with both tools, but I will investigate more into it, to see if I can find more details or something reproducible.

I will report back

@phaedrux

Implementing this in
tpreX
and
tfreeX

(where X is the tool number)
works great!

If I pull the filament out of the sensor, it says:
Printing paused
Extruder 1 reported 'noFilament'

I have 2 more questions:

#1:
Where does that massage "Extruder 1 reported 'noFilament'" come from?
I already created the "filament-errorX.g" files (where X is the tool number), but I would like to change the message

#2:
While testing this, I saw that sometimes the pausing of the print needs longer or kind of freezes the printer.

I mean the tool always stops and normally it goes back to its homing position.
But sometimes it stops, needs ~5-15 sec and then goes back.

2 times it also stayed at that position and never went back to the homing position

This machine is currently running on
Duet Web Control 3.4.0-b5

The example gcode cant be uploaded, because its ~43Mb and the limit it 4Mb

But I can show some copied snippets.

@oliof Thanks for your post.

My last slice was with the latest Superslicer Version.
It generated a gcode with comment, which was not recognized:

; estimated printing time (normal mode) = 2d 18h 36m 25s

Hi,

I'm wondering how the silcer based time estimation in DWC works.

I think that it uses the name of the gcode file and takes it, but I would like to know that for sure and use this estimation at my workflow.

For example I slice something with prusaslicer and let it add the time to the file name.

It will generate something like Testprint_24m52s.gcode and takes that time as the slicer based estimation (I think).

But when I do bigger prints which takes several days, the naming is like Testprint_2d16h27m.gcode.
This file then gives the slicer based time estimation of 1s.

Maybe I am lucky, but even on a 3days print the slicer print time estimation is really accurate and just around 10min off.
So I would like to make the slicer based print time estimation to beeing used and shown in DWC all the time.

I hope you can give me more insights of how this estimation works, where it is taken from and why it takes _24m52s but not _2d16h27m.

Thanks a lot!

It would help if you tell us what is in line 19 of the macro file.

Its the snippet that @cosmowave suggested:

	then M568 P1 R{var.temp1}

The whole macro is:

;if tools[0].state="active"
;	then M568 P0 R{tools[0].active}
;	echo "tool 0 (V6) ist active."

;if tools[1].state="active"
;	then M568 P1 R{tools[1].active}
;	echo "tool 1 (Volcano) ist active."
	


var temp0 = {tools[0].active}
var temp1 = {tools[1].active}

if tools[0].state="active"
	then M568 P0 R{var.temp0}
	echo "tool 0 (V6) ist active."

if tools[1].state="active"
	then M568 P1 R{var.temp1}
	echo "tool 1 (Volcano) ist active."

@phil333 of course... you don't need "then"! Sorry for that!

No sorry at all! I'm really thankful that you're trying to help me out with you knowledge

On defining a variable like you said, the error remains the same:
Error: in file macro line 19 column 29: M568: expected numeric operand
