@MariMakes Thanks, however, as you can see from my documented post, the issue clearly is the machine_disallowed_areas values being improperly cascaded from an Ender 3 machine profile into my custom machine profile, as illustrated and proved by the fact the problem goes away when I remove the machine_disallowed_areas values from the Ender 3 profile as well. Whenever anyone spends time and money customizing their printer for a larger build volume, they certainly are not being unreasonable to expect to be able to use the full volume they've worked and paid for. I've already had need of the full bed, and used it, for a sign. My full bed allows just over 16" x 16" in x and y. I have a small maker shop with 8 printers, 2 laser cutters, 2 CNC router cutters and 1 CNC plasma cutter.

OK, so on the chance that Cura was viewing the custom machine definition as inheriting values from the base Ender 3 definition, as though it was a parent and the custom was a child that derived attributes from it, I deleted the machine_disallowed_areas values from the base Ender 3 definition, and now the problem seems to have gone away. However, if I had another Ender machine that had binder clips and glass, I'd need (and expect) the base definition to be able to have machine_disallowed_areas values without them cascading down to the custom machine's attributes. So... I tried something else. I put the machine_disallowed_areas values back into the base Ender 3 definition, and I also added them into the custom definition, but changed all the values in the arrays to zeroes ("[0, 0]"). That also did not get a workable custom definition that had no non-printable areas.

I am on MacOS 10.14.6, and I'm using Cura 4.11.0. I have an Ender 3 v2, which I modified using an Ender Extender 400 XL kit. I created a custom machine definition json file for the modified version of this printer. It worked perfectly. Originally I was using binder clips with plate glass for my print bed, so my initial machine definition file had machine_disallowed_areas values designated. However, I recently upgraded the print bed to a PEI coated steel flex sheet, with magnetic base. Accordingly, I edited the machine definition file and removed the machine_disallowed_areas values in between the brackets, yet leaving the brackets, as illustrated in this CHEP video: Now whenever I restart Cura, the restricted "non printable" gray areas are gone, as expected. See first screen shot. However, the moment I import a model for slicing, the old, deleted restricted "non printable" gray areas reappear, and Cura won't slice any model touching the restricted areas that should not even be shown. See second screen shot. It's as though Cura suddenly switches to a "cached" version of the old machine definition json file stored somewhere (who knows). Can anyone help me know how to get Cura to actually respect the revised definition json file properly? Thanks for any tips!

OK, please disregard. I found it. The profile where it showed had a support pattern option of "grid" while the other profiles had "zigzag." The latter pattern results in auto-calculated Support Line Width. All good. 🙂

I'm aware of switching on "All" to see all the options. I've got three profiles for my printer, fast, normal, and high quality. On the "fast" profile, I have an option under Quality, to set the "Support Line Width." However, the same option is nowhere to be found on the normal and high quality profiles. Can someone help me understand this? Thanks in advance.

I should also add, that for some reason... this action: Holding Shift + moving finger on the trackpad will "pan" up or down (i.e. adjust the Z of the view). ...Only works if I am clicking somewhere below / off of the model. If I'm over the model with my mouse when I try it, it does not work.

I'm late to the party, but I have a clear answer that I did not see in the thread yet. On my MacBook Pro: Holding Shift + moving finger on the trackpad will "pan" up or down (i.e. adjust the Z of the view). Holding Control + moving finger on the trackpad will "swivel" around / tilt the view of the model. Forgive me if my scan overlooked the answer if it's already posted.
