Did a little work on the vacuum attachment today. I had a small problem. The vac hose that I have was bought to fit to the LR2 attachment, which is considerably smaller than the one for the LR3, so I drafted up a little ring that put a slightly tapered hole into a slightly tapered plug. The plug fits tight into the top part of the var part, and the hole fits the 33.x mm hose end that I have. Squished them together, and it works.
Of the 2 router clamps I printed, it turns out that the zip tie holder in one of them has something in it making it difficult to get the zip tie through, and of course, it’s the top one. (The bottom one the zip tie goes through easily. Figures. Anyway, I managed to finally wiggle it through, so now I have the hoses done. Now I just need to wire it up and I’ll be good to go.
I’m spending more time than I normally would on wire management and planning. I want this to look better, and since I have to do a lot of crimping anyhow for this project, I figured that I’d rather do it once, nicely than have to do it twice. There’s a little variability, since the current location of the control box is not going to be its final location, but it will only be moving a few inches from its current location. The difference between the length of the temporary strut and the permanent one.I just need to make sure that the wiring can handle that change when I set it up.
I do also want to set up the wiring for the laser at the same time, even if the laser isn’t here.
What I’ve seen is the laser needs a 3 wire interface to the board (+12V, Ground and PWM) which goes to its control module, and then a 4 wire interface to the laser. I think that the 4 wire interface is the better one to stretch, and have the control module mounted closer to the main board, though I think the 3 wire interface is probably easier to stretch. I’m not sure which side is less susceptible to interference and noise, but I think that I’ll extend the 4 wire harness with 18AWG wire, which ought to be thick enough to handle the power with minimal losses. It’s not like anything is going to have a truly fixed mount on the LR3, but moving in 1 dimension is better than moving in 3.
