X Y Callibration

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.

Re: X Y Callibration

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

Re: X Y Callibration

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?.

Re: X Y Callibration

Re: X Y Callibration

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.

Re: X Y Callibration

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)

Re: X Y Callibration

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?

Re: X Y Callibration

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)

Re: X Y Callibration

What do you mean with overscan?

Also, with the positive values of override (around 1%) the image is completely white

Re: X Y Callibration

I'll check HDMI settings.
Could you check the problem with white image with low values of override?

Re: X Y Callibration

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)

Re: X Y Callibration

Yes, 1 percentage should not make this much difference. Please, share your debug file. (setup page/tools tab/debug button)

Re: X Y Callibration

Use X/Y Model Size Modifier Percentage field instead of Override X/Y Resolution.

Re: X Y Callibration

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.
