Hi, Nice job with the PCB How long did it take to route it?
Are you planning to route/drill the holes as well?
So anyway, it took a bit less than two hours to trace that board out, so a single pass path would have cut it down to maybe 30-40 minutes.
[...] It wouldn't have functioned anyway if I had actually finished it since the other side is solid copper.
[...] Of course having less runout will mean I probably won't get by with single-pass trace routing, but I'll be happy to trade that out.
[...] I'm still exploring engraving cutters (angles, material, style) to find out which ones work the best and last the longest.
Drilling the holes seems simple, but there are at least three ways I can think of to do it and need to experiment to find which turns out the best. Plus each solution tends to illuminate more questions to answer and I'll have to solve those current unknowns as I discover them. It's a good thing I enjoy this process.
Interesting that photomark is using a whole different set of software to accomplish this same thing. Just goes to show there's a whole rainbow to choose from.
As for all-thread for lead screws, [...]
That's not half bad - I talked to a science teacher who started a shop with robotics parts and he used a ready bought machine at the faculty to make a similar size PCB in 7..8 hours.
A lot of HF PCB's are made with one side copper, where a small pad of copper is removed from where the through holes are - makes a great ground plane.
A rod with a splinter of wolfram (tungsten) brazed into a slit in the end and ground to a "slanted V" the shape of most engravers I've seen (I'm sure you know what I mean) is easy to grind into the size you need and is very long lasting.
Way more than in the early eighties when I first considered making one - perhaps I should get around to actually do it some time soon.But it would be more for engraving, as I prefer photo transfer when it comes to PCB's.Wonder if I could find a program to take a bitmap and trace that down on a piece of something, or are they all vector controlled.
Suitable screws can be found in car jacks and in several other places.
I've found some pretty good looking solid carbide engraving bits which come in different angles and cost around $5.
