What happened?

Hello. I'm running into this problem, sometimes gcode skips the entire layer. Trace this to a negative Z offset equal to an integer number of layers, such as -0.8mm for a 0.2mm layer height, -0.5mm for a 0.25mm layer height, etc. Seems to be an old problem, but I didn't find any issues related to it.

Because of rounding, the gcode writer write G1 Z-0 and the gcode viewer doesn't understand that.
