Data Segment Length ( Quantit圜onstraint): The number of turns per spiral subdivision.Data Rotations ( Quantit圜onstraint): The number of rotations, or turns, of the spiral. ![]() Data Radius ( Length): The start radius of the spiral, the distance between its center and its start point.Data Growth ( Length): The distance between two consecutive turns of the spiral.The object has the same attachment properties as a Part Part2DObject. It also has the following additional properties: It widens as it turns counterclockwise.Įxample Part Spiral from the scripting exampleĪ Part Spiral object created with the scripting example below is shown here.Ī Part Spiral object is derived from a Part Feature object and inherits all its properties. In the coordinate system defined by its Data Placement property, the spiral lies on the XY plane with its center at the origin and its start point on the X axis. I'll probably play around with this myself, as I've not gotten into Gridfinity yet, but I could sure use it for a bunch of things.A Part Spiral is a parametric shape that can be created with the Part Primitives command. The only thing that's not clear to me is how it prints in Spiral Vase, as the example that gave appears to have two perimeters. However, they do have a section on their website talking about how to use the project to generate files that are able to be printed in Spiral Vase mode. It appears the main portion of that project is to make files that print in regular, not vase mode. Thanks again for figuring this out, I appreciate your time in solving this! So the issue is with this project not generating the STLs correctly, and possibly having the same misunderstanding regarding vase mode :). Indeed, the "premade" STL for a similar bin that I got from Printables works as intended, and indeed it appears as a solid object in the slicer. Posted by: and - the object coming out of the OpenSCAD project is clearly not going to work with vase mode, like you have correctly deduced. That's way stronger than a single perimeter. You're probably on the right track with the wall thickness, but there's a reason they made the wall thickness thick enough to do two perimeters. But things have to be specially designed to print in Spiral Vase if they are solid objects.Ĭan I ask why you want to print this in Spiral Vase? Typically, the single wall makes something pretty fragile, especially if it's a box you're storing something in. Probably the most famous is the Octahedroflake. Now, there's exceptions to this solid model for Spiral Vase. PrusaSlicer has no issue doing Spiral Vase on that, because there's no internal geometry. The example I posted, the model is a solid. As indicated above, PrusaSlicer is trying to, and failing, to create both inside and outside surfaces. The model you are trying to print is not a solid. Otherwise, PrusaSlicer will try (and fail) to create both inside and outside surfaces, so model the outside dimensions only. If you look at Prusa's support on Spiral Vase, it says: There's a single perimeter (as there should be), and the G-code has a Z command on every step, that ever so slowly raises the head as it runs around the layer, so that it's 1 layer higher (in this case, 0.3 mm) when it completes a full revolution. True spiral vase moves the Z up slowly through the entire layer, which means that at each step it's given a new Z command.įor example, consider this sliced preview of a part I made, that I told to slice in Spiral Vase. I suggest you print a spiral belt, join the ends, and see if that works for you. It's got X, Y, and E (extruder) commands, but no Z- commands. Despite showing "two" perimeters, most, but not all the time, it only shows the tool running over one of the two perimeters:Īlso, in the above image, look at the G-code. And if you preview the tool layout, you see odd behavior on the outlines. The fact that there are two perimeters showing is a dead givaway. Okay, so loading this up, it's immediately obvious that it isn't properly sliced for Spiral Vase mode. RE: Diagonal line when printing in vase mode ![]()
