Single Macro for filament handling?

Kolbi

@bearer Yup, that's what I was thinking

I could be totally off and blind, but I can't really see a clean way to have a macro parse a file to pull data from it, to be placed in a variable for logic functions. To save what was the last filament loaded, to be used to unload or change at a later point, this is my scribbled notes to myself...

Use M291/292 for timed user input, gives ability for user to select OK or cancel.

Based on user's selection of filament type, use M559/M560 to write/write-over loaded.g file. This file would contain the g-code to heat the hotend to the desired temp. Then that macro will be called within the main macro to perform the heating cycle for load / unload change.

Example:
M117 "Heating extruder for XXX."
M104 S210 ; PLA nozzle temp set
M104 S235 ; PETg nozzle temp set
M104 S250 ; ABS nozzle temp set

For PETg, loaded.g would contain:
M117 "Heating extruder for PETg."
;M104 S210 ; PLA nozzle temp set
M104 S235 ; PETg nozzle temp set
;M104 S250 ; ABS nozzle temp set

For PLA, loaded.g would contain:
M117 "Heating extruder for PLA."
M104 S210 ; PLA nozzle temp set
;M104 S235 ; PETg nozzle temp set
;M104 S250 ; ABS nozzle temp set

But what happens if the file doesn't exist and is looked for??
Or if somehow the user did not use the script to load the filament? If it looks for the macro 'loaded.g' and it doesn't exist how it it gracefully know/ detect the file doesn't exist?

i think you could solve the parsing my just executing the file and use the object model to store variables.

to deal with missing files i suppose you could set a flag before calling M98 and make sure to clear said flag in each file to be executed.

I'm sure clever people will come up lots of ways to handle such things when the full support for using variables are implemented sometime in the near future.

@bearer It all looks like it should be very doable with everything mentioned above, I just need some time off work to start trying it out - I was also making sure that I'm not missing something, like some sort of built in feature that already does this.
I'm completely new to duet so it is all an adventure at the moment

?!? Can state.status be used within a macro to determine if the machine is currently printing? Or will it simply return 'busy' because a macro is currently being run?

if state.status == "idle"

EDIT: It appears this should work, ref: https://forum.duet3d.com/topic/14013/triggers-within-homing-files/12

I tried the following example but it will not work. When looking at the state.status from within a macro, it will always report 'busy'. Is there any other way, something I'm missing, that will let me know that a printer is not currently in printing something/ when it is idle (besides current macro)?

; If the printer hasn't been homed, home it - But first check if printer is idle

if state.status = "idle"; Will never be idle when runnig within a macro?!?!?
   M117 Printer is idle, checking if homed.

For the filament 'sub'macro, the following works. It is its own sub-macro that writes/overwrites a file called filatemp based on when the user exits the macro:

while 0=0; endless loop until canceled by user

  ; Set PLA temp
  M28 "0:/macros/filatemp"
  M117 "Heating extruder for PLA"
  T0 ; Activate Hotend
  M104 S200                           ; set nozzle temp to 200c
  M109 S200                           ; wait for extruder temp
  M29
  M291 S3 R"Filament Handling" P"Filament type currently set to PLA. Press cancel to save this selection or OK to proceed to next filament type."
  
  ; Set PETg temp
  M28 "0:/macros/filatemp"
  M117 "Heating extruder for PETg"
  T0 ; Activate Hotend
  M104 S230                           ; set nozzle temp to 230c
  M109 S230                           ; wait for extruder temp
  M29
  M291 S3 R"Filament Handling" P"Filament type currently set to PETg. Press cancel to save this selection or OK to proceed to next filament type."

  ; Set ABS temp
  M28 "0:/macros/filatemp"
  M117 "Heating extruder for ABS"
  T0 ; Activate Hotend
  M104 S250                           ; set nozzle temp to 250c
  M109 S250                           ; wait for extruder temp
  M29
  M291 S3 R"Filament Handling" P"Filament type currently set to ABS. Press cancel to save this selection or OK to proceed to next filament type."

  ; Set PC temp
  M28 "0:/macros/filatemp"
  M117 "Heating extruder for ABS"
  T0 ; Activate Hotend
  M104 S270                           ; set nozzle temp to 270c
  M109 S270                           ; wait for extruder temp
  M29
  M291 S3 R"Filament Handling" P"Filament type currently set to PC. Press cancel to save this selection or OK to proceed to next filament type."

Anyone have a nicer way to do this?

Kolbi

I have it working for the most part, had to make two files with third one auto-generated. These are the only files in my macro directory so that the user interface is streamlined on the paneldue 5.
The macro 'Set Filament Type' generates the 'Heat Nozzle' macro based on user input - kinda awkward but it works.
The macro 'Filament Handling' detects if filament is loaded or not, then heats up nozzle using auto-generated 'Heat Nozzle', and performs load or unload base on filament detected status.

I want to add a third auto-option to 'Filament handling', based on if it is currently printing or not. If it is currently printing then it would automatically proceed to a changing of filament routine and not give load or unload as an option.
If anyone knows how to reliably do this, determine if a print is in progress at the time of macro execution, please let me know.
Any and all feedback is appreciated. Thanks!

I suggest you look for state.status != "printing" instead. Here's how RRF determines state.status:

// Get the status index
size_t RepRap::GetStatusIndex() const noexcept
{
	return    (processingConfig)										? 0		// Reading the configuration file
#if HAS_LINUX_INTERFACE && SUPPORT_CAN_EXPANSION
			: (gCodes->IsFlashing() || expansion->IsFlashing())			? 1		// Flashing a new firmware binary
#else

#endif
			: (IsStopped()) 											? 2		// Halted
#if HAS_VOLTAGE_MONITOR
			: (!platform->HasVinPower() && !gCodes->IsSimulating())		? 3		// Off i.e. powered down
#endif
			: (gCodes->IsPausing()) 									? 4		// Pausing / Decelerating
			: (gCodes->IsResuming()) 									? 5		// Resuming
			: (gCodes->IsPaused()) 										? 6		// Paused / Stopped

Didn't work when printing from SD card, had to use

if state.status != "Processing"

It needs some refinement but it meets the original goal:

If anyone wants to see all the sys and macro files, they are located here: https://github.com/rkolbi/RRF-machine-config-files/tree/master/Prusa MK3s

I updated the macro set abit. Now the load/unload routine sets the filament type system-wide / in DWC. This is good because then when in DWC, it shows the correct filament loaded and also that if you're using the filament config.g you're good to go.
The other change is that the 'Set Filament Type' macro will not let you change filament type if the filament is currently loaded - makes sense to me.
Since I don't use DWC when normally using the printer, the load/unload filament macros within DWC are empty - when in DWC I'll still use my macro.

The three macro files are here:
https://github.com/rkolbi/RRF-machine-config-files/tree/master/Prusa MK3s/macros

I'm happy with the macro set operation and usability. If you have any thoughts on how to improve them please let me know.

Cheers,

This is the latest version - most likely won't change until variables are enabled in the firmware.

Use the included Macros for filament handling.
To make filament loading, unloading, and changing the most straightforward and simplistic possible evolution, I have made a macro set that is readily accessible from the PanelDue. To take full advantage of the duet filament system you will need to make the system filaments PLA, PETG, ABS, and PC. This will allow you to have custom instructions for each different filament, by adding such to the filament's config.g file. !Note: Based on my current macro version, it is required that each filament's load.g and unload.g remain empty. Placing code into these files will make these macro fail.
"Set Filament Type" asks what type filament you are going to use; PLA, PETg, ABS, or PC. Based on the selection, this macro rewrites the "Heat Nozzle" macro to heat the nozzle for the selected filament type. !Note: This macro only has to be executed once for the given filament type change as it's settings are nonvolatile, regardless of reset or power off. !Note: The script will not let you change the filament type while filament is loaded.
"Filament Handling" is for any filament unloading, loading, and changing regardless of the printer's state, printing or not. This macro will load, unload, and change filament based on two conditions; whether it detects filament is currently loaded or not, and if a print is in progress or not. !Note: The logic function in the macro retrieves the current status of the filament sensor to base the perceived desired action to enact. If your printer's filament is currently empty and you intend to load filament, please do not place it into the extruder until requested to do so by the macro. Else the macro will determine that filament is loaded and that you desire to unload filament, instead of load.
"Heat Nozzle" is created by the "Set Filament Type" macro and can be selected to heat the hotend to the set temperature for the last chosen filament type. You do not need to run this to change filament, the "Filament Handling" macro automatically runs this macro to perform the heating of the hotend to carry out the filament handling, whether it be loading, unloading, or changing.
