Thanks, reproduced. The G-Code seems to be fine, the bug is in preview. It shows the first two bottom layers on the first tick of the slider, making an impression that there is one missing.

jessegrunert commented 2 years ago

I'm not sure this is entirely a preview issue. I'm trying to slice an object in vase mode, layer height is 0.2mm, I have 5 bottom layers configured. The preview is definitely wrong, but the gcode is also wrong only creating infil layers up to 0.6mm layer height. At 0.8mm it starts the spiral up. Expected result should be infill up to 1.0mm.

@jessegrunert Please, post a 3MF. Thanks.

Bottom layers are set to 5, in the generated gcode, infill layers stop at 0.6mm. I can attach generated gcode if you want as well.

The number of generated bottom solid layers is limited by the thickness of the bottom of your object. If the bottom thickness was greater, more bottom solid layers will be generated.

This issue should be fixed. Closing.

ulab commented 2 years ago

This is not yet fixed in 2.5.0-rc1.

The preview still shows two layers on 0.2 mm height in vase mode.

@ulab I'm sorry, my mistake. I forgot to write that the fix will be in the next version. Probably in version 2.6.0.
