  1. I'm printing a large, flat object. I thought that the default slicing behavior was to alternate directions for each layer, but the Cura 3.0-sliced file is printing the same direction on the second layer as the first. I don't see anything in the settings that would affect that, but obviously I'm missing something.
  2. I assume that the stepper motors for this printer use 0.04mm increments, or something. The instructions say, "For best results, set your layer heights in 40 micron (0.040 mm) increments. For example, 0.16mm, 0.20mm, 0.24mm etc." So I'm just trying to make the Cura profile match that. I hate to experiment with profiles, because my experience has been that a badly-written profile is a good way to completely screw up my Cura settings and have to start over. But, until the printer mfr decides to produce updated Cura profiles for their hardware, I guess that's where I am.
  3. I've created a custom printer config, and I need to tweak some of the settings. First thing is to constrain the available layer heights to those that are optimal for this printer. Looking at the Ultimaker 3 definition file (and chasing the "inherits") as an example, I see the layer_height configuration options (mostly in the fdmprinter.def.json file), but I don't see how to constrain them to specific numbers. For example, let's say I want to only allow layer_height in increments of 0.04. Is there a calculation for that, or do I just define a bunch of presets, or is there a "layer_height_increm
