This snippet contains many functions commonly used by spell makers. Hope these can help you to make your spell easier. :D

PS : Anymore functions you would like to add, feel free to tell me. :p

Writing a bunch of lol code that can be wrote within 1 minutes is really worth it hmmm?

Rofl. >_<
>call SetUnitFlyHeight(u,zOffset,0)

By the way, can we PLEASE stop calling everything Utils?

It's really freaking annoying! =[
(And probably decreases the time between your system being released and hitting the graveyard by 50%, which is probably around 3 hours. :()

That's actually really quite good, I hear. <_<
Click to expand...

It is. GetWidgetLife is the fastest native (or so I've heard). However, it is a BJ function that would not get inlined. Why have such simple bj functions when they're so easy to just write inline anyways.

The coding is fine. There's just no one that would actually NEED a system like this. It's a bunch of random functions that aren't even related.

    Crazy how much 3d printing has come in the last few years. Sad that it's not as easily modifiable though
  • Varine Varine:
    I bought an Ender 3 during the pandemic and tinkered with it all the time. Just bought a Sovol, not as easy. I'm trying to make it use a different nozzle because I have a fuck ton of Volcanos, and they use what is basically a modified volcano that is just a smidge longer, and almost every part on this thing needs to be redone to make it work
  • Varine Varine:
    Luckily I have a 3d printer for that, I guess. But it's ridiculous. The regular volcanos are 21mm, these Sovol versions are about 23.5mm
  • Varine Varine:
    So, 2.5mm longer. But the thing that measures the bed is about 1.5mm above the nozzle, so if I swap it with a volcano then I'm 1mm behind it. So cool, new bracket to swap that, but THEN the fan shroud to direct air at the part is ALSO going to be .5mm to low, and so I need to redo that, but by doing that it is a little bit off where it should be blowing and it's throwing it at the heating block instead of the part, and fuck man
  • Varine Varine:
    I didn't realize they designed this entire thing to NOT be modded. I would have just got a fucking Bambu if I knew that, the whole point was I could fuck with this. And no one else makes shit for Sovol so I have to go through them, and they have... interesting pricing models. So I have a new extruder altogether that I'm taking apart and going to just design a whole new one to use my nozzles. Dumb design.
  • Varine Varine:
    Can't just buy a new heatblock, you need to get a whole hotend - so block, heater cartridge, thermistor, heatbreak, and nozzle. And they put this fucking paste in there so I can't take the thermistor or cartridge out with any ease, that's 30 dollars. Or you can get the whole extrudor with the direct driver AND that heatblock for like 50, but you still can't get any of it to come apart
  • Varine Varine:
    Partsbuilt has individual parts I found but they're expensive. I think I can get bits swapped around and make this work with generic shit though
