I was playing around with the height modifier this morning and noticed that the Layer Slider on the right (in preview mode) seems to display ambiguous numbers. It appears my model which is 40mm high has 200 layers. This is obviously equals the height divided by layer height 40/0.2=200. So when I scroll up and down the layers numbers don’t show 1-200 but change to higher numbers in the center. If you right click and jump to layer (in my example 100) it jumped to 203 which sort of defeats the object…
Anyone else noticed this?
Sure looks like a bug…

Is there something different about that layer? Not seeing that one my side, 1.06.02.04
Man I don’t even get the pop up window to enter the layer I want to jump to. I think it is broken for sure.
Using Studio 1.9.7.52 for Windows, the layer numbering is correct, but Jump To Layer does not work. After slicing, it is shown as a right-click option but does nothing at all instead of bringing up a box to input a layer number. After that failure, the right-click menu is unavailable until the model is re-sliced.

I’m still having problems with jump to layer not working
Jump to layer is working here now.
Studio 1.10.1.50, Windows.
I am trying to resume a print from a layer but the layer jump function doesn’t seam to be working. I right click the “+” on the slider select jump to layer and enter enter the layer number I want to jump to. When I send the print to the printer it just starts printing from layer 1. Am I missing something or dose this function just not work? I am printing with a p1s and on the lates version of bambu studio as of 11/15/2024 Windows 11.
The Preview tab is just that, a visualization of the model the gcode will tell the printer to make. Nothing can be changed from that tab except the view and destination of the sliced file. It does not send any information to the printer until you hit print or send, then the entire sliced model is transmitted at once. It does not interact with a print in progress. Prints always start from the first layer.
If you want to print only the upper half of a model, go to Prepare and move the model down through the plate. Only the portion above the plate will be sliced and printed. Or use the cut tool to remove the lower portion.
“Jump to Layer” is just a more precise way to move the slider in the Preview tab.
