Well took a bit of learning but your guide sure helped.

Looks like # 21 here.

Also looks like I'm on firmware 1.2....guess I should update it..Gonna do some poking around to see if there's firmwares on your site or something


Email me. Programmers fall into 2 batches and the code is not interchangeable. Well, 3 now with OLED versions. I'll recompile using your serial number and send you the hex file for updating.

The GSN serial number can actually be overwritten via another command in the EEPROM. However, there's a serial number that prints at boot up that is hard coded and cannot be overwritten. Probably better to use that one.

Oh there is a way!

Ok I'm gonna go ahead and noob this up. Is that terminal, CMD, or which program?


RealTerm, or any other terminal program.

I just got a sample part of the FormLabs Tough 2000. Not bad. This could probably be used to make connectors. It deforms a bit before cracking, which is good. It can also take a hit with a hammer without cracking. A connector would have thinner walls and so will take less impact but it would probably work.

If work buys some for testing, I'll sneak in some test prints.

Wait a sec... How do we tell which serial number we have?


=P


Weird. Some site formatting won't let me display the command but its GSN surround by <>

Got my case from Schwanck. Looking good! Just need to get a black USB cable instead of my red one.

I purchased an Elegoo Mars for this project.

I have been experimenting with mixtures of a base black anycubic resin and Siraya Tech's Blu resin, which is a much tougher resin for functional parts.

I have come close to figuring out a solution I am happy with through experimentation, but I have two main issues I'm running up against:

1) Parts of my edges are not forming correctly and so the edges don't have the sharp clean lines I'm looking for. I have been watching videos on manually adding supports and I think that's my answer. I'm not even really overly concerned with that, should be an easy one to solve with a bit more experimenting.

2) When I test fit parts, they work beautifully. However, what I have observed after many test fits is that the material is kind of wearing a bit and leaving a chalky residue. I'm not overly concerned about this for myself, but if I do a larger run of these for the community, I want to provide a product that looks good and functions properly. I think I wouldn't be overly impressed if I bought a cable from someone and it started looking chalky after light use. This one is really bothering me and I'm not sure there's going to be a resin solution to the problem.

I'm starting to think maybe using the resin for the casing after I get that dialed in and then looking toward a carbon fiber material like you use in your patch cable for the connectors themselves.


You may need to adjust the models for SLA as well. You may know this but with 3D printing you usually start off with a design that should work, and then tweak it to work better with your 3D printer. So most of my parts have been tweaked to work well with the Markforged Onyx. The models may need tweaking for printing in other materials. You can use Tinkercad to make simple changes. I actually build all my models in Tinkercad from basic shapes.

What type of material did you end up printing with? I couldn't get great prints with PLA, I bought a resin printer and am playing with that, but I'm not quite sure that's the way to go. I know Kevin uses a carbon fiber material but that material is $200/spool and requires it's own separate 3D printer from any normal printer you use, which is probably cost prohibitive for the average person.


Which SLA machine? FormLabs just announced Tough 2000, which is their closest resin to ABS so far and they claim itís great for connectors.
