what does orange color of profile items mean?

[curasurf 4]

I remember that the orange color means the item value is illegal. But the values seem to be ok and the model can be sliced successfully.

 

What does the orange color mean? Thank you!

Red means illegal.  I think orange is legal but "not recommended" or "beyond calculated value" or "do you really want to do this?".  If you are running a 0.6 nozzle and want that initial layer height at .666, then yeah, it's going to turn orange.  If you make the layer height 0 it will turn red.

Hi @GregValiant  It's a 0.4 nozzle. The process has been used on other software for long. Thank you for your comments!

That's why it's orange then.  The recommended Max layer height for a .4 nozzle is .32.

Orange is indeed the warning value. We set these ranges based on what we know about 3D printing, but we also want to allow as much freedom to the users as possible (and well we might also be wrong sometimes!). As such we only put settings in error mode if we know that they will lead to machines breaking or just impossible situations (eg; speeds of 0).

That being said; if you aren't using a weird machine / material, the settings should not turn orange.

Hi @GregValiant  @nallath  My line width is 0.6mm. And It seems that layer height of 0.333 should be ok for 0.4mm nozzle. Yes, they are on the border, but have been used for many prints. Thank you for your comments!

The limits that we set there are obviously based on our own experiences. It's entirely possible that there are things that you can do to get it to work.

Hi @nallath   I fully recognize your expertise in the fusion printing process. In fact, your job is really great! Thank you!

What is good enough depends on the model and application, of course. But 0.4mm from a 0.4mm nozzle as in the pics below, is moving away from the optimum. I think coloring it orange is good, meaning: "possible but not optimal". But maybe make that color a bit more gold-orange instead of deep orange (e.g.: RGB=255,180,0), so it visually moves further away from the red?

 

Both left blocks in the overview-picture are 0.4mm layer height, from a 0.4mm nozzle. Top row printed at 50mm/s, bottom row at 10mm/s. It prints well, but you have very crude layer-lines, and you start to get deformation. And cooling is difficult and slow, as the heat from such thick sausages takes time to radiate out, so it tends to sag while cooling. It has a nice sparkle in it though for transparent materials.

 

From left to right: layer height = 0.4mm, 0.3mm, 0.2mm, 0.1mm, 0.06mm. Top row printed at 50mm/s, bottom row at 10mm/s. This is clear PET. The brown discoloration is because it is staying long in the hot nozzle at low speeds and thin layers.

@geert_2   Very interesting experiments and comments. Thank you!
