I have found it best to make a text file with the instruction set for my gpt coding projects. Then if I don't like what it produced, start a new chat with edits to my text file and resubmit it. If I ask the gpt to just adjust what it already created, often times it will rewrite the entire thing changing pinouts, changing variable names, and other assorted random stuff. however if I just resubmit the text file into a new chat after I edit the text file with refined parameters I can generally get to a complete project in just a few iterations. I love it and it saves a grip of time. Soon I think that we will be able to conversate with a gpt like talking to a coworker, and it will work as expected. That stuff is getting better all the time.

In my experience, drywall screws are brittle and if it ever snaps flush with the mounting surface, it will require drilling out with a hardened bit. So, it works as a jerry-rigged solution, but it might also be a maintenance time-bomb. Whatever works though! Thank you for the centerpunch idea. That's straight up legit, which makes me think maybe there is a centerpunch cartel out there hiding this information from the masses. 😀

There's a very specific confluence of skill at demonstration here. It's an intersection of engineering, computer science, material design, and functional "stoichiometry." It's this unique skill to make EXACTLY what you need, no more or less, out of what boils down to useful garbage. To do it, you have to know what "things" are made of and the characteristics of that material, how they're put together, and what each of the "vocab terms" associated with the bit of garbage being smashed together mean. Then, you have to know what techniques are needed to manufacture the piece, and then how to create the signalling/coding to make it all work together. What's really sells it though, is this understanding that it's purpose-built. Even if a tool has "general" use, it's built AS a tool to DO a distinct "thing."

I had an idea roughly based on glass DRO scales. Speckle a plate of glass with something like a paint or a silvering solution. Then use a small camera to look at the glass scale on the table (use the camera as a optical sensor). The system would have a recorded map of the glass, and use it for getting an absolute position.

Then you could write a cool piece of software to map the workspace to a grid, use the mouse to plot points, have the table to move to the point.

When watching this I had the idea that for some people a good camera would be more useful than a DRO. If you often print out templates, glue them on your material and follow their lines and crosses for drilling and routing you could stay more on the analogue way of using such a cross table by zooming in with the camera and place your drill bit very exact, especially if you have to wear glasses. Of course I don't want to diminish what you did, it's great. It was just an additional idea.

I think I've seen a Heidenhain DRO that had a similar interface. It gave you position in numbers but also had a bar moving towards a target. I really wanted one like that but there is no such thing as a cheap Heidenhain. I wonder how complicated would it be to have a DRO that gave you an absolute position based on two scales. Use it in a lathe tailstock, one scale for the hole tailstock and one for the quill. I know it's easier to just mount a drill chuck on the carriage, but I thought it would be possible with something like a modified TouchDRO. Great video, take care!
