My application is the BASIC Stamp 2 Editor from Parallax. I have the old version of the Board Of Education with a serial port instead of USB, but a USB to serial adapter that has proven to work on Windows.

I see a question posted about eight months ago with the same problem. In his case, he was trying to program a radio, in my case, I’m trying to program a micro controller, but we went through the same steps and came to the same conclusion.

@Criggie a request for suggestions, but I didn’t put in a lot of effort because I was trying to gauge the room.

Having trouble accessing serial ports with Wine.

PTL, it worked! Add this as an answer (please explain what goes on though), and I’ll mark it as correct.

Right. I’ll try the second one.

@roamia tried it, the session died and disappeared before I could reattach.

Worthy of note, Plarium Play and even Mech Arena are free.

@roaima I have no previous experience with the screen command. I'll try again and do that in a moment.

@roaima Hang on, back to your first suggestion, I tried binary 2>&1 /dev/null, but that isn't quite what you wrote. Is it what you meant, or should I try again with binary > /dev/null 2>&1?

@roaima the screen command exited immediately with no output or apparent effect.

@waltinator That gave me a large file I do not understand. What am I looking for?

@roaima I tried 2>&1, and it actually made the desktop file not work at all. Will try screen...

@waltinator I will try that.

@roaima pretty sure I tried that, and it didn’t work. Am currently using ‘binary > /dev/null’ with said effects. Will try the other again.

@NicolasFormichella I thought of that too. It didn’t work.

@NightmareWolf OK, so it’s probably not saving the blend file. Why are you trying to do this, exactly?

@NightmareWolf I ask because I’m wondering if there’s another way to do this, since after some brief searching it doesn’t look like a saving option is immediately implemented. You can however try to find the python operator for saving a project file.

OK, I’ll get to testing it myself and hopefully find a solution.

try maybe: blender -b myfile.blend --python-expr bpy.ops.mesh.primitive_cube_add()

docs.blender.org/manual/en/latest/advanced/command_line/…

@NightmareWolf I would actually not use that option, since I’m not sure how to enable scripts for auto execution off the bat. I would put the script as a text block in the blend project, and then run it with —python-text MyScriptName

@NightmareWolf You can add cubes with python, you can run a python script in blender from the system command line. Will that do what you need?

@NightmareWolf you obviously didn’t understand what I’m trying to say: If you don’t intend to open an operating system, that basically means you don’t intend to use a computer. I mean, are you saying you want to launch Blender from “windows power shell“ or “command prompt” or “LXterminal“ or whatever the Apple command line thing is?

@NightmareWolf Are you referring to opening an operating system terminal, running blender in console mode (blender -b), and running a python script of the blend file (—python-text render_anim_split)?

I remember that tutorial. Off the top of my head, all I can say right now is double check it. Chances are, you skipped a step.

Nvm. Bye!

Off-topic question: does three look massively different from two? Because I always thought 2.80 should’ve been three.

So… I guess just wait for 3 to come out.

Ok, that’s probably a bug, then.

Blender 2.93.0, Windows 10 Home 64 bit.

Not for me.

I didn’t do the donut tutorial either. I just discovered object-render particles by hearing about it,

The particles do not rotate with the cube. They stick to it in the right positions, but they rotate like compass needles. If this is supposed to happen, then object-render particles are almost useless in animation.

Okay…

If I cannot rotate the cube in object mode without applying it, I cannot animate its rotation (except with animall)

But… that means that the donut in tutorial cannot be animated.

The particles have a compass effect, but it’s more about up-and-down than north and south.

… That shouldn’t have any effect on animation, should it?

Snapping… oh yeah. Transform snapping.

Yes, I put the driver there on purpose, so you could just press play and see what I mean.

@Chris I edited again.

@Chris there, I think.

@Chris I will if I need to. Let me see if I can reproduce from defaults.

The answer is updated. This file is tried and tested, and it does work. Sorry I provided an answer that I hadn’t tested myself. 😕

I don’t know how to initialize chat yet, so that something I need to learn. Meanwhile, I will work on re-creating blend file and node set up. I did have to reconnect all the nodes after creating the same material slots and assigning the same materials for the two objects.

@hellocatfood OK, confirmed, for whatever reason it doesn’t work unless both objects have the same material slots.

@hellocatfood huh. I tried it out and you’re right: it didn’t work. Pretty sure it should, though. Maybe this is a bug?

@hellocatfood wait a minute… There it went! OK, that is a bug. I have the same node setup as before (although I did add material slots with the same materials for both objects), but something refreshed, and now it’s working.
