copy and editing a simple definition like the 101Hero or the 3dator. They reference the fdmprinter.def.json file
@Aldo should this be done in the 'applications' folder or in the 'config folder'? I don't see that many .json files in the 'config folder'.
btw I rather update my 'pino' machine than make a new one from a copy since I open project files a lot and they refer to the 'pino' machine I have at the moment (I think...)

Just copied the "fdmprinter.def.json" to the config folder and changed
"visible": true,
"platform": "platform.stl",(visible was set to false and platform line was added)
However I don't see a "meshes" folder, I created one to test, but didn't work.
There are no files in the "variants" folder, but there are config changes in the "definition_changes" folder
I have an ".inst.cfg" in there.
I see in the .json file a line with:
"has_variants": false,
so I don't think the variants are necessary...?!?
Some extra information why I want this: The bed size is 1000x600mm (big!) and there is a glass chip of the bed on a certain spot, I have a stl file with a hole on that spot I want to have as a buildplatform. Now I just load that file, but it would be luxury to have that default in Cura.

But that's what I did now.
@BastelWastel what exactly did you do...?
where did you create the .def.json printer definition?
I would like to do the same thing
I found a .def.json file in /Applications/UltiMaker Cura.app/Contents/Resources/share/cura/resources/definitions/fdmprinter.def.json (on MacOs)
but editing that file didn't work
I also found these /Users/..user../Library/Application Support/cura/5.4/definition_changes/pino_settings.inst.cfg
but couldn't find any .json files there...

I don't see that much difference after many years with regular PLA, but they get more dirty. In theory ASA should be better outdoor, but there is hardly mechanical properties needed for the statues and planters.
On the other hand, if it is easy to change the part, it should be worth a try and replace when needed. You than at least buy some time to find a better solution, or maybe you find out that this is a good solution.
A bit more difficult when you 'sell' the product since you must communicate that this is a beta test for outdoor 3d printing. But most (all!?) of my projects include this kind of expectation management.

That's why I was thinking of removing the PLA shell after the concrete sets and having the 2 resin layers on top of the cement.
ah, I thought you wanted to print with a resin, but I am told photopolymers get quite brittle outdoors...
58 minutes ago, TotalNEWB said:Ballpark numbers 10-20K? more?
For me the challenge is to get it as affordable as possible. 20K is a challenge, it is not difficult to spend 50K on the same object. But you will get different details. On the other hand, if you can do more things yourself, also the (metal) construction and have enough time, 5-10K should be feasible.
Usually the more time you spent the better it gets. But many times good enough is perfect.
I have a PLA sculpture hanging outside for more than 8 years now and it is still hanging there. This is only a single wall print and mostly completely hollow.
You can consider to cover the pla print with a coating and keep the PLA.
If using concrete, maybe interesting to do a sort of roto moulding on the separate parts before assembling. So the objects have for sure the concrete more to the outside.
Printing moulds is more difficult for the details. Also becaause of the postprocessing of the prints (grinding/sanding/welding), that is more difficult on a negative object.
I printed a lot of objects, then made a mould (eg silicon) and then casting the final object in the mould.

Hi,
Thanks @gr5 for tagging me... : )
The size is really doable. I work a lot for/with artists and advertising agencies. There are some things I would see different I think.
First of all is the costs. The focus here is on materials. The real investment is in 3d modeling and print strategy (knowledge). No matter what printing technique you use. In most of my projects, material costs are mostly a small fraction of the total project.
About the finishing... If you have no experience, you might get very disappointed since your expectations might differ than what could be feasible. And what if the expectations are higher, then it could very well be the lack of print strategy knowledge...
The layered structure looks very complex and why is the concrete a must? sometimes it easier to make it cheaper/faster and maybe print a new one if the older one failes than design and make a very robust and 'hooligan proof' object. Also since the print costs are mostly a fraction of the project cost/time investment. (Not always, but yes if you design in a way where you need as less as possible post processing)
8 hours ago, TotalNEWB said:However, his statue is solid, and I want just a shell.
His statue is most likely not solid...! FDM is almost never solid and uses infill structures.
Printing large things is not difficult. Printing large things within a reasonable amount of time is the challenge. Therefore the print/slicing strategy is very important. And when reducing the time, a reprint (of some parts) is also not a big problem.
Just some thoughts......

That is what I will check indeed...!
(but so far no problems anymore, maybe just lucky...)

update on last print behaviour...
didn't try to remove the material, but started right away with warming up the core
I noticed that the fan was not on untill I opened the lid (I think?!) or above about 150 deg...
Then the fan turned on. I suspect moving the lid did the trick, so will check with a new fan or check the wiring.
BUT... When I tried to remove the material I noticed it was not stuck at all...?!?! like 'normal' behaviour...
I also noticed an extremely large prime blob which I cannot declare.
to be continued....
-
Same problem and a material remove tip.
Have the same problem after every print since last week as well. Checked the fan immediately after the first failure since that was my usual suspect. Fan is running... hard to tell if it is running normal speed or a lot lower though...
Then switched to another (same size 0.4mm core) same problem...
I have something else though, I am running an gcode file generated in the past and needed a new batch of these objects. The printer (UMS5) says that I wouldn't have optimal performance, but didn't expect this... : )
TIP to remove the material which works for me:
- heat up to 245-260 deg
- wait a while
- then go back on menu to the material and push the three dots to right to 'move the material'
- pull (really a lot!) and hit the move button 2 times per second.
(don't keep ou finger on it since it will go to fast and grind into you filament)
Try to avoid to break the filament, but I guess you don't do that on purpose...
Interesting that this happens the last few weeks...?!
Have to check the firmware and the exact cura version i used for these files..
Next up is double checking or replacing the fan to see what happens...

Je zou ook kunnen spelen met 'horizontal expansion'.
Wanneer ik dunwandige producten ontwerp doe ik dat vaak met een wanddikte van 0,1mm (of nog minder) en in Cura de horizontal expansion op 0,5*nozzle (of line with).Of ik ontwerp het massief en dan in cura zonder top/bottom en zonder infill.
(Tip: Wellicht je vraag in het engels stellen, je hebt dan veel sneller een antwoord... : )

@rooiejoris recently complained to me
I didn't complain, I asked a question... : )
And I can imagine that a full proof script is difficult, but I think a partly working work around could be quite helpfull already

Adding the printer works...!
But that shouldn't stop me from dropping by in all offices....
Thanks...!

.. but adding another printer with the same def files works!
can't find the cache files on my mac
how do you mean 'exactly' adding a printer with the same def files...?!
add printer, close cura, copy paste definition json in the new printer definition json...?!

Hi,
I want for an experiment slice something with 4 extruders. I managed to change the definitions json and added the necessary exruders json files and Cura starts OK. I can chenge the number of extruders in the machine settings, but I don't see the 3rd and 4th extruder in the GUI/menu on the right. I also don't see in in the right mouse button menu.
Is this a [known?] bug or am I missing something...
some snippets of the definitions json I changed:
"machine_extruder_trains":
{
"0": "ultimaker_original_dual_1st",
"1": "ultimaker_original_dual_2nd",
"2": "ultimaker_original_dual_3rd",
"3": "ultimaker_original_dual_4th"
},

~/Library/Application Support/cura/machine_instances
This folder should also be easily accessible through the Help->Show Configuration Folder menu.
Thats it, thanks also for the shortcut in the help meu.

Found my Aurora A3 printer!
It's in:
C:\Users\[username]\AppData\Local\cura\machine_instances\Prusa+i3.stack.cfg
Any ideas where the location could be on a Mac...?!
changed and added some machines, but cannot find any .cfg in the user/.cura folder with the date of today and/or a name that I would recognize.
[there are older cfg files, but not from today]

tried to rename to home_offset, but then i think more is renamed
the error now is:

I use the githuib.com/marlinfirmware since that has the M163 included [which I need...]
I seen something like set_home_offset and home_offset, maybe it is a different name?!

almost working I gues, just don't understand where to copy/paste these lines:
static void lcd_init_z_adjustment();
static void lcd_prepare_info_z();
static void lcd_prepare_adjust_z();
(placed them in ultralcd.h but have no idea why i did that : )
and I get an error:
'add_homeing' was not declared in this scope.....?!
did I miss something...?!

I use Neotko style as well, sort of... I prefer the name of the object first and version as well
Many times I copy all files on the sd card to the folder called "old" so you can find the current files faster.
Important is also that the names are not so long, when working with octoprint in the 8.3 format when printing from SD. That means extension on .g [instead of .gcode]
When I resume prints I use the same name but ending on r1.g, r2.g etc...
And for production on multiple different machine include machine name [uMO, UM2] and nozzle size [without a dot]. Never included PLA in filename since that is my default, maybe add material when it is different.

Hi,
I managed to install all the packages and dependecies for compiling the cura engine on mac OS 10.9.5 [woohoo!!], but when compiling i get an error which is source related I think:
[ 7%] Building CXX object CMakeFiles/_CuraEngine.dir/src/PrimeTower.cpp.o
/werk/github/CuraEngine/src/PrimeTower.cpp:54:40: error: variable-sized object may not be initialized
int max_object_height_per_extruder[extruder_count] = { -1 }; // unitialize all as -1
^~~~~~~~~~~~~~
1 error generated.
make[2]: *** [CMakeFiles/_CuraEngine.dir/src/PrimeTower.cpp.o] Error 1
make[1]: *** [CMakeFiles/_CuraEngine.dir/all] Error 2
make: *** [all] Error 2
any directions how to solve this...?!

[edit: i did change the id and name in the json and then the machine shows up in the add printer list, still want to know where the added printer json file is [or is that referred to this json file?!]
Where is that list of json files on a mac...?!
I see a list in contents/resources/cura/resources/machines
but when I duplicate and rename a pirnter there, it doesn't show more printers...
I did add 2 other machines, but don't know where the json file is to edit the nozzle size
[interesting is that the wall tooltip refer to the nozzle size but that value is nowhere viewable....]

You only need a little bit of overlap; Just about the same as you have with 'normal' wall/ infill overlap (about 15%). If you ensure that the walls between the objects are not straight but have a shape with some noise, you can improve the bind between the objects.
Yes and no...
The overlap will 'weld' the object together, with pla it works really well, but the adhesion between layers and also between parts is many times not as strong as the layer. Especially with other materials [ABS, PC] or fiber inserted materials [markforged] you would like to see a more integrated layering strategy.

[this is the 3rd time I challenge students from TUDelft to print larger by combining multiple fast/accurate XY frames with a slow XYZ frame to speed up production, but keep de resolution. Ther whole project is only 6(!!) weeks. See also the project form 2 years ago: http://kamermaker2013.weblog.tudelft.nl/]

I now have a solution, but even worse than editing the fdmprinter.def.json (SORRY! but it works for me for now...)
edited the fdprinter.def.json with a buildplate stl I created myself didn't work
with an existing stl it did work, so I renamed my stl to an existing one
really bad solution, but for now good enough for me.... (SORRY again Aldo... : )
