Most invert or reverse functions fail because of one of these issues:

1. Wrong data type
You may be passing a value, string, array, or boolean that the function does not support.

2. Incorrect return value
Some invert functions return a new value instead of modifying the original one. You might need to store the result in a variable.

3. Logic error
If you are trying to invert numbers, signs, or boolean values, the logic must be exact. For example:
Boolean invert: value = !value
Math invert: value = 1 / value
Sign invert: value = -value

4. Scope issues
Variables may not update because they are outside the function scope.

If the invert function is related to image editing

Problems usually come from:

1. The layer is locked
Unlock the layer or convert it to a normal editable layer.

2. Wrong selection
If only part of the image is selected, only that part will invert.

3. Adjustment layers
Some tools invert only content layers, not adjustment layers.

If the invert function is in Excel or Google Sheets

You may be facing issues with:

1. Incorrect formula
To invert order, use INDEX with ROW or a simple reverse array formula.
To invert sign, use =A1 * -1
To invert boolean, use =NOT(A1)

If the invert function is from a game or application

Many games use an invert-y-axis or invert-x-axis function for controls. Issues usually come from:

1. Settings not applied
You may need to restart the game or save settings manually.

2. Controller conflict
Another input device may override settings.

A couple of things you can try:

1. Check the grayscale levels in the pattern. If the imported art is mostly light tones, the carve will always be shallow when inverted. Darkening the original image before importing can sometimes help.

2. Run the Pattern Editor and increase the contrast. This can push the highs and lows farther apart and give you more definition once you invert it.

3. Try using the “Scale Z” or “Height” adjustments inside the editor rather than the project depth settings. Those usually give better control over raised carvings.

4. If the snowflake is very thin or fine-lined, you may need to thicken it slightly so the machine has more material to raise.

As for adding an image, you can usually do it through the forum’s attachment option, but some user levels have restrictions. If you don’t see an upload button under the text box, you may need to wait until your account has the required permissions or link to an external image host.

Hope this helps, and feel free to share the file if you want someone to take a closer look.
