Re: Spool Holder for N2

I also have another version of the above spool holder without the fidget spinner bearings. These actually may be the best version as it has enough friction to naturally let the filament slide out. I am testing both situations.

Re: Spool Holder for N2

So my latest design is an external spool holder with fidget spinner bearings and using the guide tubes supplied with my Raise3D N2. This has reduced the friction forces from the default spool holder at about 1.2 N to around 0.2 N Default Friction around 1.2 N highforce.jpg External Spool Holder less...

Re: Spool Holder for N2

While I haven't had many issues with my filament being loaded in the stock position, I did have some issues using a Wood filament. The extruder feeder gear would slip on the filament in some cases. I do not have an easy way to feed filament from above, due to the location of my printer, so I decide...

Re: Please Share your Ideamaker Slicer Settings for the Dual N2

Walshlg I remember somewhere you mentioned Ninjaflex was easier to use than semiflex. Any chance you could share your ninjaflex slicer settings (zip them)

While at it why not include your PETG settings

Re: Welcome to Raisers New Home!

We have received the advise from JohnSays. He thinks that not stopping heating does more help to him. But we still think stopping will be more safe. We will consider to add an option for both of this. You can enable when you want to print or load or unload immediately. And disable when you only wan...

Re: Conducting Filament

OK here is an idea, perhaps if you annealed with current going through it would reinforce the conductive pathway!! Try inserting something like a spade plug and anneal with maybe 100mA and see if that improves conductance! Might be a waste of time but might not! :D Someone better with electricity t...

Re: Conducting Filament

So I tried annealing for only a few hours. Build plate at 110 C, glass cup upside down over the print. Got the PLA to about 60 C and the Conducting to about 75 C. Then let it cool over half hour to about 45 C and tested the resistance. Seemed to reduce all resistance by about 600 ohm. I did not feel...

Re: Conducting Filament

I strongly suggest that you give annealing a try, it might improve conductivity a lot I like the idea of after printing covering the object and raising the printbed to about 80 C, then reducing the print bed temperature over a few hours to room temperature. The other idea is to anneal in the oven b...

Re: Conducting Filament

With the resistance values you have measured and the appropriate supporting electronics, this filament opens up many possibilities for practical use, resistive touch sensors for one. Great idea. I think there might be lots of things the class could do. I found a link on thingiverse http://www.thing...

Re: Welcome to Raisers New Home!

Reminder after loading and unloading filament that the temperature does not automatically turn off. Great if you are about to print something. Not so good if you walk away and forget to set the extruder temperatures back to zero.

Please Share your Ideamaker Slicer Settings for the Dual N2

Can any of the experienced dual extruder N2 users export some Ideamaker slicer settings with a little blurb about why they really like it. Curious people are using for: PLA with supports, NinjaFlex, Water Dissolvable, PETG etc. I realize that settings may be different for different climates, room te...

Re: Conducting Filament

Another idea is to design the fill yourself as part of your model. I use Blender which is fairly difficult since it is mainly for animation not 3D Printing and is difficult to make objects manifold for 3D Printing. Are you suggesting I make the object have it's own layers or inside columns? See ima...

Re: Conducting Filament

I just printed a part with 5 shells and the effect was that the small section areas were effectively printed solid, whilst most of the thicker sections were filled at the infill percentage. This may work for your model. Thanks tja, that is a brillant suggestion, I will try that when the ProtoPasta ...

Easy printing = pla but I have personally switched exclusively to PETG - its stronger, less brittle and can tolerate heat and water exposure better and it prints better imho.



Interesting Walshlg. Can you give us some temperatures and speeds your working with.

Re: IdeaMaker Supports so close together?

Pillar refers to the area where you want to put support. Not the shape of support. ideaMaker only has two types of support shape, grid and line. If it jumps out no support, please add, that must because you have choose support here. But if you have set manual support before slice, you don't need to...
