This was dragging like… idk - turtle? snail? I’ve collected all the parts looong time ago, but had zero time to do anything with them. My son was waiting for this build very anxiously, and considering I was always busy with other things he… STARTED BUILDING IT!
Oh my, oh my! I’m so happy! He is only 9, and we started talking about CNC probably 2 years ago, so he’s waiting for it like 20% of his life
I’ll try to update you here how he is doing, and this is probably going to force me to help him, coz he’s not going to know how to wire stuff and all.
His extensive LEGO experience apparently is helping a lot! Money well spent? I guess?
We came up with some original solutions, community didn’t see coming. The use of stickers, and crumbled biscuits (on the right side of the photo).
Please do not mention oversized linear rails - they will become useful or cut.
Next on the list is new surface for the table (this one is temporary), then installing pipe on it.
And the wiring. I have cable and necessary plugs + crimper, but I feel like I will use way to much time on this, coz my crimping skills are low. Is that ok to cut wire stepper has in half and solder additional length in the middle?
Crimping shouldn’t be required if you have extension wiring with LR kit, see https://docs.v1e.com/lowrider/#wire-routing, this is LR4 doc, but the advice for this step is helpful for LR3 too.
Personally soldered Butt Connectors to extend wiring on my LR3, since then have become less avoidant of crimping…
SN-025 crimper (recommended by Jamie) for dupont helps to crimp firm and small enough to fit the plastic shells.
Personally find DuPont 2.54 pitch unnecessarily finicky. If struggling, I’ll initially partially crimp the wire sheathing using IWS-2820M open barrel crimper, then, finish crimping both pairs of metal tabs against the laughably thin wires with SN-025.
I tug and continuity test wires and endstops through out the assembly. Easier to fix a break the sooner they’re detected.
Aaaaanyway… I do have some freebies MDFs, but they are not big enough to cover my whole work area as spoilboard. Is that ok to make patchwork-spoilboard? out of 3 strips? I’m thinking about connecting them on the ribs of the table. And maybe I will first throw OSB on the table skeleton?
For someone not confident in soldering or crimping, these things work really well:
(Snips from the US orange big box reseller (WAGO lever connectors) or US internet bookseller:)
I’ve started recommending these for folks that don’t have a lot of wiring experience and want to build things that are reliable and maintainable on the first try.
Oh, yeah, thanks for that! I use those when wiring 230v, but didn’t occur to me I could use them here as well I will probably go with soldering though. Or maybe use them temporary and solder later?
Anyone can advice on patchwork tabletop/spoilboard?
