Please explain: custom named and defined tokens per material

Please explain: custom named and defined tokens per material

Postby b-morgan » 08 May 2018, 14:03

The lack of a good manual for 1.6.2 is depressing :(

In the 1.6.2 Features under G-CODE IMPROVEMENTS is this bullet:

    New G-code Tokens for box temperature, prime pillar position, and the tuning value, and custom named and defined tokens per material

Can someone explain what these tokens are (by name) and how does "custom named and defined tokens per material" work (i.e. how do you use it)?

I've searched kisslicertalk.com, the internet (with Google) and can't find any useful information using "custom named and defined tokens per material" as a search string.

Well, all the built-in tokens are listed on the Settings/Printer G-code tab.

Most are fairly self-explanatory and very few are needed to generate great prints.

Only a couple may need explanation:

<MATL> this token is replaced in the generated G-code by the content of the upper left box on the Settings/Matl G-code tab

<TUNINGVAL> this token is replaced when the Wizards/Tuning Wizards is active and set to <TUNINGVAL> G-code token only. A good example of this is tuning for Linear Advance. Set [*]N Layers to 1 and in the N[*] Layers tab, enter

Code: Select all
M900 K<TUNINGVAL>


User-defined tokens can be created per material; you may find that every time you change extruder (material) that you need a material-specific setting not available elsewhere, so create your own token and add that token in the appropriate Printer G-code section.

Hope this helps.

I guess I'm just slow or getting senile. Can you provide an example of a per material user-defined token, please?

I am trying to get my LulzBot TAZ 6 with both the original single extruder and with the Dual Extruder V3 configured so I can use KISSlicer on a regular basis.

I print with PLA, PET-G, a little ABS, and PLA/PVA.

The TAZ 6 start gcode is fairly complex as it involves nozzle wiping (with temperature changes) and auto-leveling in addition to the usual homing of the X, Y, and Z axis. Complicating this is the fact that the built-in tokens listed on the Settings/Printer G-code tab aren't being substituted in the printer G-code Prefix.

Any chance you could copy/paste your prefix g-code section in a post?

It would also help if you did likewise from a slicer known to work as required.

Peter

P.S. Example custom material Gcode:

Code: Select all
<CURRENT_LA_SETTING>=[M900 K29.2    ; Linear Advance for this material]
<HOME_AND_RETURN>=[
G91   ; Set Relative
G1 Z1    ; Lift Z by 1mm
G90    ; Set Absolute
G1 X0 Y0 ; Home
G1 X<NEXTX> Y<NEXTY> ; move to next XY
G91    ; Set Relative
G1 Z-1    ; Lower Z by 1mm
G90    ; Set Absolute
]


Yes, it's a nonsense example, but I really don't have much use for this feature; others do. To use, you simple add <CURRENT_LA_SETTING> or <HOME_AND_RETURN> on a line within one of the Printer G-code tabs.

Thank you for the examples, they helped alot!

Here are my current KISSlicer Prefix Gcode for both my single and my dual extruder. They don't work, of course, because Prefix doesn't know these tokens. I could try moving the temperatures to the custom material Gcode, but I don't know if that will help. The <BED> tokens appear more than once because CuraLE and Simplify3D have separate settings for the first layer.

Here are my start gcodes for Cura - LulzBot Edition (CuraLE) for the single extruder and the dual extruder V3. I have also included the end gcodes because there are some token substitutions in there as well.

Single start gcode:
Code: Select all
;This G-Code has been generated for the LulzBot TAZ 6 with standard extruder

Re: Please explain: custom named and defined tokens per mate

OK, just checked the single extruder and you are using incorrect tokens.

<WARM> and <MAIN> are not valid; they should be <WARM1> and <MAIN1>

For the dual extruder, M104 (according to G-code wiki) does not have a T option: http://reprap.org/wiki/G-code#M104:_Set ... emperature

So you may have to select each tool before setting the temp. But I don't know your printer, so I may be very wrong!

Peter

P.s. will have a look at your second post later (sorry, very busy at the moment...)

You are correct in that neither http://marlinfw.org/docs/gcode/M104.html nor http://reprap.org/wiki/G-code#M104:_Set_Extruder_Temperature show a T option for M104 or M109 but I started with the start gcode as delivered from LulzBot which does use a T option. A quick look at the Marlin 1.1.8 sources shows that the T option is valid for M104, M105, and M109.

I changed <WARM> to <WARM1> and <MAIN> to <MAIN1> in my single extruder start code and sliced a model. That fixed the issue and it looks like token substitution is active in the Prefix code.
