Dynamic lift and wait times

[msspad]

UVTools is a serious work horse for me, thanks for all your work! Some questions & remarks:

1. https://github.com/sn4k3/UVtools/wiki/Rest-times-and-TSMC#how-to-tune-acceleration Is there a way to see the default configuration (acceleration, jerk, etc) of a Phrozen Sonic Mini 4k (or any Chitubox machine besides elegoo code)?
2. Dynamic lift: I thought it can make sense to set a lower lift speed for a higher lift height (because more mass should be pulled with lower speed (or even better acceleration)? a warning prevents this currently
3. The format of "Wait times" 2/0.5/0 is: 2 seconds wait before cure / 0.5 seconds wait after cure / 0 seconds wait after lift. correct?
4. "Edit print parameters" with ctb v4 changes 4 parameters even without touching anything:

1. It should be possible with a serial link, but not that easy... See: https://drive.google.com/file/d/18Ud_x-aR85m5qi4uiX9_ze26UC_jC4kA/view?fbclid=IwAR0tLzLQnCN4j1EHJK0zeDOEmWeYW_sROovdGYMQllT6UdmvzG8IVrceZw8
2. Make sense to set a lower lift speed for a higher lift height: That is how it work already, if you read description it will tell you that.
3. Correct, highlight labels show tooltip with meaning
4. Because i dont allow 0 as value, it's normal thing. Nothing wrong, no side effects

I could add that variation if you wish, and let user decide which approach to take, still min and max would be clamp

[msspad]

I have no facts to show that it works better, it's only more intuitive for me to understand. I would use this option if I had a choice.
Clamping: the formula squeezes all values into the range of [minLiftSpeed, maxLiftSpeed]. However, if any variable is non-integer, clamping is still necessary for numeric imprecision.

[sn4k3]

Ok i can give the option.
Just tell me what that options names can be called (to show on GUI) what can i call them?

[msspad]

not sure, how about "full range"?
description "squeezes lift height and lift speed within full range of min/max values. E.g. the layer with the least pixels gets minLiftHeight and maxLiftSpeed, the layer with the most pixels gets maxLiftHeight and minLiftSpeed."

[sn4k3]

Need to be more specific, we will have two methods.

Method1 = My
Method2 = Your

I need name and description for both. Can you purpose something?

Also give the math for LiftHeight, you only post for Speed

[msspad]

Method1 = traditional
Method2 = full range

The correct formula, by the way:
pixel_ratio = (layer.NonZeroPixelCount - minNormalPixels) / (maxNormalPixels - minNormalPixels); // pixel_ratio is between 0 and 1
liftHeight = (_minLiftHeight + ((_maxLiftHeight - _minLiftHeight) * pixel_ratio)).Clamp(_minLiftHeight, _maxLiftHeight);
liftSpeed = (_maxLiftSpeed - ((_maxLiftSpeed - _minLiftSpeed) * pixel_ratio).Clamp(_minLiftSpeed, _maxLiftSpeed);

[sn4k3]

Ok, here the new aspect

[msspad]

looks great!

1. how about replacing "mass" in first 2 lines of the description, e.g.
   "Generate dynamic lift height and speeds for each layer relative to its number of pixels. More pixels in a layer require higher lift height and lower speed while fewer pixels can go with smaller lift height and higher speed."
2. last line, I guess it technically a challenge to add a link to "few printers support"?

Technically pixels are the mass, the more pixels you cure the more the mass you have. I think mass term is more easy to understand for users?

Correct, had to change a lot just to able to insert links (Richtext)

[msspad]

yes, mass is also fine but pixels is already often used in UVTools and it also appears in the dropdown "...number of pixels...". You can put mass in the dropdown, then it's at least consistent in the window?

WIll update accordingly
