CURA

Cura is the recommended slicer for Artemis, so we should probably have a thread for it. I have been using 3.4.1 - which is a bit later than the version mentioned in the Artemis docs. Today I got an automated notice that 3.5 is available - and an invitation to download it. Anyone try this yet, either...

Updateing computer hardware - GPU "needs"

A bit of a tangent, but with fused deposition (AKA 3D printing) comes 3D modelling and once the novelty of printing Yoda heads and sketching up simple geometric forms wears off ...its time to start "Meshing around". Creating 3D models from a stacks of photos (photogrammetry or somesuch nam...

Re: ABS recommendations

I agree the aquanet hairspray WORKS very well, but I have been allowing it to "dry" and then heating the bed to 40 deg C and (because I used to do it on my Max V2) I apply two coats of Elmers disappearing purple. Not sure that the glue ADDS anything, but I don't dare stop using it. BTW, th...

Re: 2 Color printing with CURA

That seems like a whole lot more trouble than it would take to modify a slicing program to at least switch extruders for support material and/or at layer numbers.

Anyone know of slicers that CAN do that ?
slic3r for example, or matter control ?

Re: Artemis Linear Rail Mainentance

I had used a "donated" make-up eyebrow brush to put a little grease into the slots where the balls ride. Given the diameter of the balls they will pick up a decent film and distribute it to the rest of the rails if you (for example) just run the bed leveling program. I doubt that I can eve...

Re: Large objects.

The description for "Enable support floor" suggests that this would put down a more solid foundation on the glass, however looking at the first few layers doesn't show any difference - also the print time and amount of filament used don't change, so I doubt that this actually does anything.

Large objects.

Right now I am trying to print a thin object that is too big in two dimensions to lay flat, in fact it is too big to lay on any of its surfaces, so the only way I can get it within the build envelope is to tip it up onto a very short edge. As currently arranged in Cura it is 10 mm x 241.9 mm x 306.8...

Re: Drag knife.

If one wants no offset at all, controlling the blade is necessary. A servo is a good idea, and would work in most cases. But a servo also has a rotation limit. It cannot rotate more than XX°, XX often being a bit more than 360°. That means you would not be able to cut a snail shape.... unless you p...

Re: Drag knife.

Why drag it? A cheapo servo could rotate it. I agree, if I were striving for "perfection" a little bit of path look-ahead could indeed aim a knife in the intended direction of cut. It is quite possible that this is matured knowledge at some high end machines. I am being selfish, for MY wa...
