Show me examples of your start and end gcode.



  • I must be the only person that likes the printer to play a little tune when it finishes, like the dishwasher and washing machine 🙂



  • @deckingman:

    There is not much point in my posting my start and end gcode files

    I would disagree. Even though your setup may not be directly relevant to mine, I would still likely learn a great deal from seeing what is possible in other configurations. A clever idea has merit beyond its substance.



  • @DADIY:

    Mines much more simple, but I have a delta.

    I like that. I'm totally using that.



  • @carlosspr:

    Additionally I have some settings on Slic3r for Start-Gcode based on filament type. For example for PETG I am setting the PID parameters tuned for my PETG printing temprature and have tuned the Pressure advance to 0.3. This is my Start Gcode for PETG filament type:

    That's interesting, do you notice much better temperature stability by using temp specific PID tuning?

    I've kind of just targeted the middle temp range I print at and stuck there. I had done tunings at different temps in the past, but never thought to have them be filament specific like that. Good idea.

    If you use the "Filaments" feature in DWC, you can just change some params (PID, retraction…) when loading the filament, although those params are just executed during load and unload, and not after a reboot :m...

    Cheers

    Got any examples? I actually did a cursory google search to try and find some jingles or some tool to convert them to tones. No such luck.



  • Alright, I "composed" an end print jingle after watching some youtube videos of singing washing machines and dishwashers.

    Nice turn of phrase but I don't do anything clever - just different. Unless you run 5 extruders and a mixing hot end my start and end gcode files really won't be any use to you.

    Here is one example though. I have a number of different printer configurations for various Diamond hot end assemblies that I switch between. Eaxh printer configuration has a different start gode file. I also sometimes run post processing scripts that I've written and the ";begin" and ";end" comments in the start and end gcode files act as "flags" or markers when I use these post processing scripts. Also note that initial tool heating is not in my start gcode because it is part of my homeall.g file (I use the nozzle to probe the bed so I warm the hot end to soften any oozed filament).

  • @okercho:

    If you use the "Filaments" feature in DWC, you can just change some params (PID, retraction…) when loading the filament, although those params are just executed during load and unload, and not after a reboot...

    That is why I have a file [c]current_material.g[/c] which currently contains this:

    M98 P/macros/Settings/PLA
    G10 P0 R150 S210 
    
    

    The Settings/PLA contains the retraction settings.
    My Filament load macros use M28 and M29 to write the [c]current_material.g[/c]
    for PLA:

    ; create file to set options on startup
    
    ; current_material.g
    M28 /sys/current_material.g
    
    M98 P/macros/Settings/BDP
    
    M29 /sys/current_material.g
    
    ; load settings from startup file
    M98 P/sys/current_material.g ; Load material.g to apply general settings
    
    

    And I added [c]M98 P/sys/current_material.g[/c] to the end of [c]config.g[/c] so that it gets executed after boot. Voila! 😉



  • @Phaedrux:

    I am having some ripples on temperature. I noticed that by setting specific PID for that temperature the ripples are reduced to +-1.5 C.

    The last part of your end gcode is the same as mine but M116 for me just get ignored which is annoying, have you ever had that issue?
