load unload macro with endless loop and cancel condition
-
Thanks!
1.
Thanks now it works but I had to take out the last "/" before config.g
2.
Yep
We are some sort of "brothers in lazyness" I guess
3.
What? I do not get it... -
@LB the 3 was just saying that the @garethky gcode was right (sorry if it have a meaning or something that i don't understand, i haven't the greatest english x) )
It's weird that you had to take the last "/" before config.g, it's working for me ^^ -

@LB Nice that it works now

It is not "really" working clean and cool, rather a big "workaround" to get it done somehow, but letΒ΄s see how this all evolves the next month.

@LB How does it look now ? and what's left to do ? It's really cool to see how everyone do it their ways

I have upgraded to 3.2 final and I no longer get the filament name in
move.extruders[n].filament
insideload.g
. This now mirrors the behavior of tool changes where there is no tool selected whentpreN.g
is called. I'm not against the logical consistency of this. But for tool changes we havestate.nextTool
which contains the tool being loaded, we don't have a similar concept for filaments. I think we should ask for amove.extruders[n].nextFilament
variable in the Object Model.Using this to find the filament macros directory is a neat idea. Although what we have essentially done is eliminate the need for M703 almost entirely.

Still works for me
1/10/2021, 10:53:33 AM echo move.extruders[0].filament ABS
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.2 (2021-01-05)
Duet WiFi Server Version: 1.25Are you sure that there is a filament recorded in filaments.csv?
If there is a filament loaded in all tools the next tool is accessable using
echo move.extruders[state.nextTool].filament -
Maybe this is because I'm using the SBC? (Duet 3 running 3.2_final and a Pi)
Whenever I get into
load.g
(either loading or changing filaments) the filament variable is empty:; load.g echo "Current Filament: '" ^ {move.extruders[state.currentTool].filament} ^ "'"
Current Filament: "
-
@garethky i've just tested you echo, it works for me too, but i think it store the name after the load.g or config.g.
I'm loading it myself using M702 to clear filament and use M701 S"(filament)" but i don't use load/unload.g and config.g (maybe i'll be using it later but not for now) so it do nothing instead of changing the filament loaded name ^^
I also don't use the loading/unloading function of DWC as i have a all-in-one load/change filament macro -
The documentation for M701 states that it stores is after
load.g
exits. If you echo insideload.g
, then it hasn't happened yet, so the echo will be empty.I want to use the GUI to change filament and guide the user (me ) through the process with helpful prompts.

@garethky
I use a dummy fan name to store the name of the filament to be loaded.
My setup is done so that I can ensure the correct filament is loaded for a sliced file, but DWC filament buttons still functions normally.
Ultimately I want all the files in the filaments folders to be identical, but can't quite achieve that yet.In Prusa Slicer start G Code I have
T[current_extruder] ; select tool M104 S0 R0 T[current_extruder] ; Set temps to zero to stop slicer adding them M106 P[current_extruder] S0 ;Start with fan off M950 F3 C"duex.fan3" Q0 ;create a dummy fan so we can use it's details as variables M106 P3 C"[filament_type]" S0 H-1 M98 P"0:/macros/filament/check-filament-type.g"
in config.g I have
; create dummy fan so we can use variables M950 F3 C"duex.fan3" Q0 ; create fan 3 on pin and set its frequency M106 P3 C"No_Filament" S0 X255 H-1 ; Calibrate MCU temp M912 P0 S-4 ; Adjust MCU temp reading to match ambient ; Tools M563 P0 S"Extruder1" D0 H1 F0 ; define tool 0 G10 P0 X0 Y0 Z0 ; set tool 0 axis offsets G10 P0 R0 S0 ; set initial tool 0 active and standby temperatures to 0C ; create dummy tool so we can store some variables M563 P2 S"DummyTool" ; define dummy tool 2 G10 P2 X0 Y0 Z0 ; set tool 2 axis offsets G10 P2 R0 S0 ; set initial tool 2 active and standby temperatures to 0C ;Select tool zero T0 P0 ; extrusion if move.extruders[state.currentTool].filament="" echo "No filament loaded. Cold extrude & retract set to defaults" M302 S190 R110 ; Allow extrusion starting from 190Β°C and retractions already from 110Β°C (defaults) else echo "Filament loaded. Set values per config for filament" M703 ; if a filament is loaded, set all the heats and speeds for it by loading config.g M106 P3 C{move.extruders[state.currentTool].filament} S0 H-1
At present I have to do this in /filament/*/load.g.
This will be easier once variables are available;; load.g ; set the dummy fan name to the filament being loaded M950 F3 C"duex.fan3" Q0 ;create a dummy fan so we can use it's details as variables M106 P3 C"ABS" S0 H-1 ; set the fan name to ABS in case this is called from web interface M98 P"0:\macros\filament\universal_load.g"
All my preheat settings and speeds etc are done in the filament/config.g
These are tuned per filament naturally; Used to set parameters for filament such as retracts, temperatures etc M302 S210 R130 ; set cold extrude and retract temperatures M291 P"loading config.g for ABS" R"Loading config" S1 T5 ;M592 D0:1 A0.012 B0 ; Set non linear extrusion M572 D0 S0.09 ;Set pressure advance M207 S1.0 F2400 Z0 ; Set retraction ;M593 F25 ; cancel ringing at 25Hz
filament/unload.g for all filaments just calls my universal unload.g
;; calls universal unload file. ;; M98 P"0:\macros\filament\universal_unload.g"
This is the "check filament" code
if move.extruders[state.currentTool].filament!= fans[3].name if job.file.fileName!=null M25 M291 R"Incorrect filament loaded" P{"Incorrect filament loaded - (" ^ move.extruders[state.currentTool].filament ^ ").

@garethky I use a macro, it show at the first page btw it's universal in one file (i just had to separate the purge loop to be able to cancel it) and i also like to be guide, i've done everything to be as simple and explicit as possible for the ease of use but i admit that it can be nice to use the built-in solution
also it detects if there's a filament, if not it skip the unload
@OwenD wow it's a nice approach ! A bit too complicated for me but man, it's nice work -
Also, if you put this in your
load.g
echo "In PETG.load, calling M703" M703 echo "In PETG.load, M703 returned" echo {move.extruders[state.currentTool].filament}
and this in your
config.g
echo "PETG Config Loaded"
Then click the load filament button in the UI, You will get this in the console:
M701 S"PETG" M703 In PETG.load, calling M703 In PETG.load, M703 returned PETG Config Loaded
If you drop the same code into the unload macro you get different output:
M702 In PETG.unload, calling M703 PETG Config Loaded In PETG.unload, M703 returned PETG
So calls to M703 inside load.g don't appear to work. This is similar to how homing calls inside a homing file are illegal, so I'm not surprised. M703 inside of unload work just fine. So I love all of the optimizations above but I cant get any of them to work. I'm just going to ignore the blank string in load.g until variables show up.
