Print only specific layer range
Sometimes there are objects with critical sections that are difficult to print and you need to experiment with slicer settings to get it right. You will need some test prints until you find the best slicer settings.
This could be improved, if you could start printing at a specific layer thereby skipping all the underlying layers where you know there will be no problems. At the moment, you would have to manually edit the g-code, delete the first layers and then correct the absolut value for the z-axis.
This could be implemented just like the way, the layers can be shown in the preview. Let the user specify a layer range and e.g. print only layers 60 to 80.
