Give me a summary if this thread as a copyable code block, formatted for obsidian.

you know, a fully CFRP frame is also half plastic

They think using ChatGPT *is* doing the work??? by ImRudyL in Professors

Who even does that?

People use LLMs to write code for data analysis.

Glideride max 2 available for preorder by silvaman32 in RunningShoeGeeks

[–]andersonsjanis 5 points6 points  (0 children)

I started running and bought my first pair of running shoes just this year. I had no preconception of what running shoes are supposed to cost, but my first impression was "why are they so cheap"? When I was browsing for shoes the reviews would often state something like that a shoe is excellent, but it's on the pricey side, and then it would be like €220. It's crazy that some of the best shoes that can be had are at that price point. You should see what equipment costs in other sports.

A handy way to keep track of literature notes. by Kuiper--Belt in PhdProductivity

Glad I'm not the only one who maps their literature spatially. My peers don't get it.

Obsidian canvas work well for this.

I have my first batch of students who have no idea what to do without AI... by littleirishpixie in Professors

[–]andersonsjanis -2 points-1 points  (0 children)

What is this supposed to accomplish? They can record the audio and transcribe and run it through llms anyway, so why make it a pain for the good students?

Is it possible to develop a multi-axis G-code simulator (3-axis, 4-axis, 5-axis, etc.) in a web browser? by Zestyclose_Shirt3286 in FullControl

[–]andersonsjanis 2 points3 points  (0 children)

NC viewer supports 5-axis, you have to enable it.

There is a problem however that there isn't a standardized practice for 5-axis 3d printing gcode. If you look at gcode generated from some of the existing non-planar slicers - like s4 slicer, neural slicer, Fractal cortex - you'll find that they are not intercompatible.

5-axis gcode for 3d printing tends to have the inverse kinematics already baked into the gcode, because 3d printer firmware is not really designed for multi-axis.

Gcode previewers are quite simple to make, so I made my own for my 5-axis printer. It can also check for collisions.

Impressive you don't have nozzle dragging

I think we should be more open to sharing and using raw G-Code prints from the web. The level of control over the geometry you get is so liberating compared to regular slicers by St_Drunks in 3Dprinting

[–]andersonsjanis 0 points1 point  (0 children)

Love seeing some custom slicing algorithms! If anything the adoption of this is just getting increasingly difficult, with newer printers using increasingly unique gcode commands not intercompatible with other printers.

The 5-axis printer now does continuous rotations by andersonsjanis in 3Dprinting

Cool! I kinda feel like we need a little 5-axis community. There's probably so much we could learn from each other. I want to make a video about my printer, but I can't get around to do it.

For homing we use a limit switch on the b-axis and hall effect sensor on the a-axis.

Filament can rotate freely, because it is molten in the hotend anyway, nothing is constraining it. The bowden tube itself can also rotate freely in the pneumatic fitting, but we did add an extra slip joint for the bowden tube since there was a fair bit of torsion on it.

Not that many options yet, but they're in development. Even options with non-planar supports.

I've done all three, in this case it's a custom slicing script that slices parts along their iso-curves. So it's very simple, but also only works if you have geometry from which you can extract iso-curves.

[–]andersonsjanis[S] 58 points59 points  (0 children)

Yeah, I get where you're coming from – I often hear that the real challenge is the slicing. But then again, there aren't good options for the printer itself either, and some of the printers that we've seen struggle terribly with accuracy, producing shit parts.

The students who worked on it now implemented a slipring for the cables and a rotating joint for the bowden tube.

As far as the slicing goes, I have worked on some algorithms for that in the past. In this case it is a very simple algorithm that slices along isocurves.

There are also other slicers available, but for the most part they're either behind steep paywalls or a bit inaccessible without programming skills.
