Different print profiles for each filament with DM Robox in Automaker.

[Mike @17bt CHORLEY, Lancashire]

Hi

Does anybody know, and I’ve tried searching..if you can assign for filament 1 one type of print profile, say 3 perimeters, 2 base layers 2 top layers, and then for say filament 2 defeating the print quality to say 1 perimeter, 2 base layers and 0 top layers. The reason I am asking is I like to make my own support structures in my CAD models, and I’d like to make a weaker more fragile substructure that I can break away easier.

When I go to Settings, it doesn’t seem possible.

PS Will Automaker ever allow an automated layer pause point to be added. It would be quite useful, rather than hanging around the printer all the time, bobbing in and out. I know you can estimate, and set a timer, but couldn’t it be added into the system.

If you create all the items in the same space in your design software then hide/delete all the supports and save as something like model1.stl then unhide/undelete these and hide/delete the model leaving the just the supports visible. save this as a different filename eg model1supports.stl

Now drag both the files into AM at the same time. They will be grouped. Double click on the support part “model1supports.stl” in the main window and choose a material on the left side.

The only other way would be to edit the gcode to tell the printer to use a different nozzle+extruder for certain sections.

We do hope to add a pause feature. There are some posts about adding pauses to the gcode on a specific layer. http://www.cel-robox.com/forums/topic/latest-v3-automaker-software-killed-gopro-support/#post-38789

OK @pete, I do the supports this way in my CAd, and export selected parts as separate STL files to group into Automaker using the CMD key in macOS when I “Add Model”. All that is straight forward and fine, plus I can select the filaments to suit for each model, but what I want to do is change the “preferences” of each filament print, as in alter the base layers, percentage fill perhaps, and top layer, so one is the standard default print quality, and the other a poorer lower quality, but still adequate as support material.

I already use tapered sections to create more space between the two structures, and work towards a bridging support at the height I require, which does allow me to tease the parts apart at the crucial points, but I am finding the top layer of the support is sticking to the the underside of the supported print.

So essentially what I am asking for is a separate profile setting for filament 2. Is this possible?

Thanks for the response.

@17bt It is not available at this time.

@bhudson OK, but if the feature was to be implemented, it would be nice if this was implemented for the QF head too, but applied to @pete‘s grouping scenario.

So instead of filament 1 & 2 in the left sidebar, you could create groups with different print profiles, that way you’d get a potential breakaway support structure using just one material by making one of the groups weaker and able to delaminate or separate from each other with a little teasing.

Mike

PS It might also be useful if the print time “estimates for head type” had a drop down selection for the DM & QF heads too, although this would only be handy if you have a DM machine, and were considering if using a QF head was beneficial.

it is quite a complex thing to create different sliced profiles for different objects within the same build, certainly a very involved process for a slicing engine. I believe Simplify3D combines the sliced files afterward.

Thanks for the link @pete, and I did check it out, as well as this video, which was something I didn’t realise Simplify 3D could do. https://youtu.be/OcddlK36OVs

This is way more than what I wanted to do, but obviously it has print time benefits the way this is implemented.

As the Robox printer is unsupported in Simplify 3D, it’s slightly academic at the moment, but I see the Cura slicer can do something similar. Just curious, can the RoboxDM printer be added as a “Custom FDM printer” so that you test this out?

I did do some more digging around, and slic3r looks like it has a similar feature too, so that you can change print properties part way through a model… http://slic3r.org/blog/modifier-meshes

I see @nebbian has been busy with moving slic3r to the Robox, along with couple of other guys too, and they are starting to get good results. That’ll be interesting when it surfaces for others.

Hey @17bt,

Thanks for posting that tutorial. I’ve had a bit of a play around with this and never got it to work before. The method in that tutorial makes sense.

 

Regarding the different slicing options, we’re trying to make this slicer-agnostic, so you can use any slicer you like on the Robox. This should really help people who want more features than the bundled version of Cura can provide.
