Relative speed settings instead of absolute about uranium HOT 8 CLOSED

I myself think we should indeed supply speeds as relative % of main speed

No, skeinforge had this, and it was horrible.

@Diad, can you elucidate? Why was this horrible?

from uranium.

Because it became an unconfigable mess, you had no idea what you where actually changing, you changed 1 thing, and other things changed with it. You had no idea what the actual speed was which was used for certain parts for example, because of ratios on ratios.

We're not talking ratios on ratios, we're talking ratios to the overall speed. I think it is the overall speed that simple users would want to modify, before going into detail and changing the separate speeds of different parts. Moreover, I think the speed of the infill is higher, because the infill can be relatively less accurate, compared to the skin.

Well, this is the entire idea of having a slider for the simple mode. Simple users shouldnt be touching advanced options in the first place (as infil speed is a advanced option in my opinion).

Yes, the whole new way of dealing with settings solves this issue much better then ratios.

I will leave this issue closed, even though I don't think your arguments are sound.

Your case would be stronger if you woud say that ratios presume linear dependencies, while the amount with which you can e.g. highten the infill speed w.r.t. the overall speed is not linearly correlated with that overall speed.

Moreover, it would introduce an extra setting: overall speed, which would mean that the system of speed settings is overcomplete; the same set of speeds can be achieved by multiplying the voerall speed by x and dividing the rest by x.

To reply on your arguments:
@nallath: Indeed simple users shouldn't be touching infill speed, though touching the overall speed might be a good way to go for a bit more advanced users.

@daid: I suppose you are referring to the fact that inactive / invisible settings inherit from their parent? That would mean we could write an inherit function which sets the infill speed to a ratio of the overall speed when it is inactive / invisible. However, this might not be such a good idea because of the nonlinearity I posed above.
