Operation: Relocate Desktop

Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am more than a tidbit ticked at Windows’ built in remote desktop. Let’s get started!

I’d like to start by saying that Windows Remote Desktop isn’t deserving of a 100% scathing review. It has its purpose. I have concluded it was designed with the tech-savvy Joe who is remoting into his work computer from home or wherever else. As long as you are just surfing the web or using office-type programs, you should be fine.

But as soon as I tried launching Minecraft (I did not test with any other games), the launcher spat out a warning. For context, Minecraft 1.14 was recently released, and I believed they had finally stopped supporting the old launcher and were forcing people to update. The new launcher also crashed the game while trying to launch it, so I spent a day looking into it and getting discouraged over not finding much of anything. I stopped short of updating my video card drivers manually without supervision.

My father finally got the drivers updating, computer glitched, and after several failed attempts, I eventually hooked a monitor back up to it. I was pretty mad when Minecraft launched right away. I pieced together from a few places that 1: Windows Remote Desktop doesn’t use the host’s graphics card like I thought; it loads a basic graphics driver that runs on the CPU. And 2: This graphics driver doesn’t support OpenGL, a library Minecraft needs to run.

Sister suggested moving the whole tower during bedtime worship. I really wanted to fix the solution I was already working on, but it would have been more expensive in terms of time, hassle, and frustration.

Windows Remote Desktop is not a bad piece of software. It was just designed with different goals in mind than I was after.

Final Question: Have you ever had a sure fire project get canceled after it was all done and set up?

Operation: Remote Desktop

Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am setting my main desktop up so I can use its full power from my laptop. Let’s get started!

While I have remoted into a computer before, this time, I have a deadline for personal reasons. I needed a stable setup that could withstand a reboot or update with minimal intervention. Since the target computer is running Windows 10 Pro, a built-in tool called Remote Desktop Connection looked like the best choice. Oh, I was in for an baaaaad time setting it up.

Things seemed like they were going almost too well at first. For one thing, it looked like the two computers had already played like this in their past, the laptop remembered the name and retained an old password for my specific tower. One problem: Where was the tower?

I must have spent the better part of a day churning over web pages looking for why my laptop couldn’t see my desktop. At one point, it I was convinced the only way to remote in was if you were already at the remote computer. It turns out, (And I’m not fully sure this is how it is, but I’m pretty sure.) the computers behind the router are seemingly not immediately part of a network. Either that or they were both treating it like a public network. My father and I worked on it for about half an hour, while I spent quite a bit of that time telling him what I tried and didn’t work.

We eventually got the two computers to see each other, but things were still not playing nicely together. We ended up checking out the firewall settings based on some of my research earlier in the day. We started flipping switches in Norton’s firewall settings until something worked. After that, we reactivated as much as possible, narrowing it down to the “Norton Smart Firewall” and I even got into some more finely tuned settings to where the smart firewall would let in remote control and, but leave on everything else. Settings (Upper right) > Firewall > General Settings > Smart Firewall > Public Network Exceptions. I enabled “Network Discovery” and “Remote Desktop Connection.”

Sure, at one point, my father had done something to where my laptop could try signing in, and we went down the wrong solution path and I ended up making a new account for my laptop. I was instantly reminded of how much I don’t like how Windows these days is built around the idea that all or most of its users are mostly computer illiterate touch screen users. I know I’m interested in social robotics, but it’s a little uncanny when it comes from an operating system I’ve grown up with.

Things became a lot easier after I managed to get a successful connection, but they weren’t perfect. First of all, my desktop immediately logged out. I was expecting something more along the lines of mirroring screens, but I can live with it this way. Secondly, I wanted to test a restart. The start menu only has a disconnect button now. I had to go back over to the tower and restart it myself. I use a lefty mouse, and both computers knew that. the result, both my computers flipped my mouse buttons, canceling each other out. I’ve unswapped the buttons on my tower.

After some basics were sorted out, I moved my monitors away from my desk and to my temporary setup, where I have my laptop and a more powerful WiFi antenna. I spent a while trying to set both my monitors up and use my laptop as a 3rd monitor, but it doesn’t look like it’s happy with that arrangement. I set my bit monitor to my primary display, and when I say to extend my desktop to my other monitor, it deactivates the laptop screen.

I still need a reinforced mouse pad, but I’m otherwise all set up. Sure, I elevated my laptop body so the screen would line up with the desktop monitors (The whole reason behind the desk is because of the whole battery drama I’ve written about in previous posts), and I would still like to get it working exactly how I want, but that doesn’t seem to be available right now

Final Question: When was the last time you used a driver CD?

Troubled Laptop Tries to Takes Up a Task

Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am working on my laptop again, this time to get it to remote in to my tower and remain stable. Let’s get started!

As of starting to write this post, I still haven’t finished. I have a week before this project is “due,” so I still have some time. But so far, I’ve encountered half a score of problems and solved/bypassed/made provisions for bypassing most of them, the first of which was the laptop not even booting correctly. It brought up the boot menu and refused to boot the hard drive several times until it got sent to diagnostics, where it froze. My father advised I pull the chord, and I booted it again. I had a double take when I spotted Windows loading.

Since both machines are running Windows, and the target machine is Windows 10 Pro, Windows comes with remote access tools built in. I’m using those, as they’ll hopefully run the lowest risk of complications and have more features I won’t have to fight the systems for, like dual screens.

My tower doesn’t seem to like being remoted into. I followed at least a couple tutorials and visited both the legacy control panel and the newer, more touchscreen friendly, settings menu (I do not have a touchscreen for this machine). These sets of settings seem to ignore each other, though I could be wrong. It’s very annoying. I believe it’s what’s keeping me from making a full breakthrough.

In other news, I tried reaching out to an appropriate discord server for my new long-term project, but it seems I’ll need to keep researching to find a complete workflow, or if it’s even possible outside a dedicated studio.

Final Question: I’m just going to re-run my last question, now that I’ve sent another clue: What do you think I am researching?

Laptop Still in Trouble

Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am still sort of in-between two major projects. Let’s get started.

The story so far: A while ago, my red laptop stopped recognizing its power cord. The apparent problem was a piece of the power port breaking off. After replacing the cord and later the internal port, the laptop is permanently tied to its power cord.

My father and I tried to fix it today, more my father than me this time. I loaded an old set of BIOS onto a thumb drive and he flashed them… after the list of updates that is. Even though it looked like the most recent version for my exact machine make I could find, it still complained about it being an older version. Good thing I managed to

My father also tried a cold boot, but nothing ended up working. Hopefully a genuine part will let the battery charge again. Otherwise, either a new motherboard or a new machine may be in the near future.

Final Question: The scope of my project this week was a bit smaller than usual. This is in part because I have been researching for the feasibility of my next big project. What do you think it will be?

Planning a Semi-Sealed Night Light Part 7

Good morning from my Robotics Lab! This is Shadow_8472, and today, I am inching forward to a stop on my current long-term project. Let’s get started!

I finally added a hole for the lamp base in my model. The pegs for the screws still aren’t in there, but I have made accommodation for their addition. I started with an cylinder object and scaled to the correct sizes. I positioned it in the optimal spot to get a visual proof of concept, but I eventually remodeled it to have a better number of vertices. My model is still on a 4 way symmetry, so I needed it to be divisible by 4; and the screw posts need to be on a symmetry of 3, so it needs to be divisible by 3 as well. I already had 40 points to merge, so it needed to be at least 40. Therefore: I gave it 48 points around the approximated circle and made some loop cuts accordingly.

I made a plan to start prototyping, but I noticed something. Sometime during the week, I arranged my Blender window to cover both my screens and set up my small screen to display different wire frame views of my project. I noticed on one of these views that something I did caused some of the loop cuts used for keeping edges sharp even with the subdivision modifier to go slightly out of alignment, and a face normal appeared facing inward along such an edge. I think it was a rounding error or something. Annoyed, I told Blender to remove doubles and I resharpened the edges.

Another incident while modeling happened in the way I added the hole in the bottom of my “house.” Before, it was a simple grid. I just scaled it down, then stretched the corresponding edges to meet the corresponding point on the model cylinder-cone. (I think I may have modeled that a little incorrectly as well, scaling the Z axis alone when I should have just scaled along the edges themselves. Good thing I kept the progress in an old layer.) I ended up with a squished grid and ugly quad geometry… and eventually some unacceptable triangles. By the time I noticed, it was too late in terms of actions to undo my remove doubles command, so I ended up removing bits of the squished grid and replacing it with some much simpler geometry.

I approved my own mesh for prototyping and pulled in a new cylinder and applied a Boolean modifier so I’d only print the ring for a test fit. (Another stay thought: the power cord would have also had issues with the ring I was making.) After catching myself from accidentally sending the .stl file directly to the printer, I went to the slicer and had to go around a few times to figure out the scale. I ended up making a unit cube and figuring the correct scale is about 5BU (Blender Units) to 1 cm, and I am working on a centimeter scale.

Finally, I got the test print to the printer, and I had the drippy white filament again. It didn’t start extruding again, and the raft started separating on the first set of passes when it was supposed to stick to the (absent part of the) outline. It curled on me. I reduced the extrusion temperature by ten degrees and tried again, only to have stuff curl on me on the next, tighter layer.

At this point, I’m thinking I will need to put this project on hold until I can properly fix my printer. It’s not working as intended, and I don’t know what to do with it.

Final Question: What in the world is going on with my printer not starting extrusion right away for the initial outline?

Planning a Semi-Sealed Night Light Part 6

Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am once again picking up the night light project. It’s been a rough week progress wise, so there isn’t much progress. Let’s get started!

The next task is modeling up the print and executing it. It took me a while, but I finally broke off the first piece: actually modeling the lamp base. The lamp I took apart is a sphere with a flattened base. I used a flattened cylinder and scaled up the proportions to the size of the base. The greater radius and height were spot on accurate on the metric system, so when it came to the curved edge of the smaller circle, I rounded to the closest millimeter.

The next challenge is refining the base model and integrating it into my house structure. The base has three screw holes I intend to use to fasten it to the cover as it prints. At some point, I’ll need to model the screw holes in. I’m just glad I managed to get it in at all. However, realized that stock Blender is not the right tool for the job.

Before my next printing project, or sooner if I really need it before then, I will want to find a plugin for Blender that adds some missing CAD functionality. Already, I have been missing the ability to measure between two points of a model, and I had to scale the models using a known size and modifier factors instead of just making something x cm tall. I will say Blender did treat me nicely when I pulled it across my second screen and set it up with multiple angles of my work. It felt good to finally have a visual of how big the base/lamp will be relative to one another.

The next major chunk of work should be modeling up pins I can attach the lamp base. I’ll likely need to underestimate a little and won’t get as tight as a fit as I did with the Pi camera because I won’t have the luxury of sanding. On the other hand, a little cleanup isn’t out of the question.

Final Question: Do you know of any good CAD plugins for Blender?

3D Printer Online Again

Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am bringing a good report about my 3D printer. Let’s get started!

The problem so far: My 3D printer has had some issues with filament running through the extruder tip when it shouldn’t. The plastic semi-remembers its curl from the spool, so it curls around and touches another hot spot on the extruder tip. In addition: This would drag along the initial couple inches of extrusion, keeping the printer from laying the important first outline when making the raft. I even observed stuff peeling off the printbed a couple times.

While I was at investigating printer problems, I got some cleaning filament and played around with using it for something other than a print; some had come with the printer, and I took it for normal material. I followed a tutorial to clean the printer, and got most of the stuff in the printhead out.

I was never able to get the printer to start extruding right away, but by raising the print bed, the troubled corner stuck without the outline. I still had a print I wanted where I would have a hollow cube, but the support structure would account for more than half the weight. The solution: print one side and two edges twice and glue the halves to each other. I think it took on the order of eight hours, and within four hours of coming off the print bed, one of the prongs had easily snapped. I don’t plan on fixing it, nor do I plan on replacing it at this time. The design was flawed; it was only half a centimeter thick, and I think it needs a full centimeter.

Either way, with this distraction out of the way, the printer is a bit cleaner and working correctly again. I can now return to my bigger project. The next step is with Blender.

Final Question: Unrelated: I started a Spigot Minecraft server this week for family and a few friends. What are some plugins you have had fun with in the past that would work for multiplayer cooperative on a small server?

3D Printer Diagnostics

Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am going seemingly nowhere with my printer. Let’s get started.

I got some cleaning filament today. It looks just like the “sample” that came with the printer. It doesn’t have a spool. It is a translucent white when solid. However, it’s much longer and came with two twist ties to hold it together. It actually extrudes clear and goes milky when it cools.

I spent a while messing with the cleaning filament. I shoved a bunch through the extruder tip and it still ooze a little, then curl around to touch another spot on the extruder tip and form a loop instead of a thread. I developed a hypothesis that the natural curl of the filament was influencing the curl of the extruded material, so I tested it by flipping the roll on the holder. The curl eventually went the other way, supporting my hypothesis. The printer does not appear to be clogged.

I still have a bit of gunk I want to get out so it doesn’t show up in random spots on my important, white print. I found a guide [LINK], but I seemed to regress in my abilities as I went along. The first try was okay, the second one seemed a bit broken, and the rest didn’t even come close. At one point, I even had the filament coming out a completely wrong part of the print head. I ended up turning the printer off until I can research it a bit more, but the guide I linked did say something about maintaining pressure for a couple minutes. I did manage to get a bunch of stuff out, but I have my doubts as to if I even got close to all of it.

Final Question: The curl seems to be a works as intended, but my main problem still exists. Any ideas why my filament is trickling a little when it’s otherwise warm but not extruding?

Planning a Semi-Sealed Night Light Part 5

Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am going over no tangible progress. I ran out of time debating the future of another project with someone, and not even that is resolved. Let’s get started!

I haven’t been able to print anything all week. Whenever I do, the extruder tip is a little runny when it should be stopped. It ends up curling around, then sticking to the side of the tip. I cleaned it off multiple times before I realized what was going on, and I haven’t been able to figure out the correct keywords to search for the problem. I think the problem may be because the printing temperature is too hot for this particular spool of filament. The tip may also have a little clog frustrating things.

I also figured out what was with some miscolored specks in different prints I’ve done recently. The first time I spotted them, I thought they were just dust that had gotten into the print job that really didn’t want to come out. Now, I know it’s residue from previous spools. While this may just look ugly when using a single kind of plastic, if I start switching between PLA and ABS regularly, I will want a cleaning filament. I’ll want it sooner if my problem above involves a plugged tip.

In other news, my friend, who I still want to print this night-light up for, has had a situation change on her. I just found a lamp base I could use, but I may need to make the whole thing battery operated instead.

Final Question: What could cause the printer tip to leak, almost as if slowly extruding normally?

Planning a Semi-Sealed Night Light Part 4

Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am printing a thin box frame the maximum size of my 3d Printer. Let’s get started.

Workflow wise, things were fairly straight forward, though in reality, things were overlapping, as usual. The workflow started with planning. I want a physical model of how big I am able to print. I toyed along the production line between Blender, Cura (the slicer), and the printer before settling for a squished “cube” that will scale to have 5mm edges and corners. A power outage during the night caused me to lose my model, but I was able to load my hollowed out cube again from a .stl file. Interestingly, it was converted to have triangular faces, so I had to turn it all back into quads before I could continue.

Meanwhile, my early cube prototypes’ rafts wouldn’t start out correctly. The extruder tip would start moving without the plastic sticking until a few inches down the line. This problem looks like the exact same one as when I printed 36 coins at once for the meetup with Tango a year ago. That time, I could just discard the malformed tokens, but this time, it’s a whole print depending on this line.

I’ve investigated the matter by learning enough G code to read the instructions the printer was following, and I get the idea it’s following them correctly. Link to a Wiki. I learned a bunch, but I literally don’t have anything to show for it this week. No cube, not even one on the printer. I’ve tested a number of theories, including retracted filament to goopy nosel. I’m out of time, but the first thing for next week is checking out the print bed, a factor I dismissed earlier on because of its resemblance to the coin problem earlier. I will say though, that I do have the bed a little lower than I have had it before, so that may be the case.

Another unsolved problem: Whenever the printer boots and I try printing the hollow cube, I’m finding the printer ratcheting when it tries going beyond its print range. I’ve had this happen a couple times, but it stabilizes after a couple false starts without me seemingly doing anything.

Final Question: Two: What’s with my delayed extrusion start? What’s with the printer glitching and self-correcting?
