Hi,
I'm using build 1382. Neither X/Y resolution nor Override X/Y resolution have any effect on the actual size of the resin part.
I've changed override from -100 to 100 and the result is the same.
My X/Y resolution is 41,66. I've changed to 20 and to 80 and the size doesn't moves.

Resolutions only effect slicing so you need to reslice your source file to see any effect.

Thank you for your reply.
Do you mean is necessary to recreate the plate?.
Does this affect only to resolution parameter, or applies also to override?.
Offline
all resolution related changes need recreate, You can press recreate button on plate to make it effects.

Good night,
I'm still struggling to calibrate my printer. I recreate the plate whenever I make a change in any parameter, but still not complete success. I need to make my part smaller. I'm using Override x/y parameter.
With Override x/y -2,5 and x/y model -3,5 the part is X=20,49 Y=20,38
With Override x/y -3,5 and x/y model -3,5 the part is X=20,36 Y=20,30
With Override x/y -4 and x/y model -3,5 the part is X=20,44 Y=20,35
The part should be X=20 and Y=20.
By making Override x/y more negative, the part should be smaller, but It doesn't. When I reach -4, the part starts to be bigger.
Which is the problem?.
Which is the procedure should I follow to get the printer calibrated?.
Thank you.

Are you using different X/Y resolutions? Remove Y resolution if you do not different x/y resolution.
Currently percentage effects resolution this way:
resolution / (1 - percentage/100)

Sorry to say so but still not working.
X/Y resolution 41,66 Override x/y 0 x/y model size 0
The part should be x=20 y=20
Part printed x=19,81 y=20,00
So I've to enlarge in the x axis by 100,959%
Using this value in the formula above it results in a negative value -0,00959 affecting the resolution.
Does makes sense a negative value?
Any other way to calculate the percentage to override in an easy way?
How this resolution modification affects the actual size of the part?

It make sense to use it but I guess it is a overscan issue with your display. Try solve it by changing HDMI settings (config.txt)
Offline
What do you mean with overscan?
Also, with the positive values of override (around 1%) the image is completely white
Offline
I'll check HDMI settings.
Could you check the problem with white image with low values of override?
Offline
Still having problems when I need to override the X/Y resolution. When I use 1,0 the image goes so large that the whole image is white. I'm not having override problems. I can see it by pressing the layers button.
The formula you wrote some lines above is valid?
resolution / (1 - percentage/100)

This is the image when override is 0,0

Yes, 1 percentage should not make this much difference. Please, share your debug file. (setup page/tools tab/debug button)
Offline
OK, I'll share my debug file as soons as I arrive home.

Use X/Y Model Size Modifier Percentage field instead of Override X/Y Resolution.
Offline
OK. Thank you.

Hello
After reading more topics about this problem I still can't solve X/Y distorsion.... im printing a cube 20 x 20 mm and getting smaller size as it should be. changin parameters in resin profile shows different numbers but the model is the same. And I'm allways recreating a model after change, even deleting it and uploading it once again but still no success. May I get a help where and what to change? You mentioned "X/Y Model Size Modifier Percentage field" but I can't find that field.
