I couldn't find the thread

## Seve — 2026-10-10T04:36:15.916000+00:00

the route names are still problematic, everything should have an actual net name

## Seve — 2026-10-10T04:36:27.659000+00:00

it looks like you might have via in pad in a couple places

## Seve — 2026-10-10T04:36:34.372000+00:00

probably ok tho

## shibo — 2026-10-10T04:36:46.991000+00:00

The area is too tight

## Seve — 2026-10-10T04:37:03.520000+00:00

i mean i don't know if they'll charge for that

## shibo — 2026-10-10T04:37:14.520000+00:00

Net names need to be more descriptive?

## Seve — 2026-10-10T04:37:26.081000+00:00

they are literally ROUTE_23

## Seve — 2026-10-10T04:38:14.101000+00:00

this is really hard to understand if you connected your JST properly- it has to match Rishabh's

## Seve — 2026-10-10T04:39:36.826000+00:00

because i use a particular type of cable

## shibo — 2026-10-10T04:40:16.862000+00:00

I don't see that name in the schematic

## shibo — 2026-10-10T04:40:44.460000+00:00

Does that mean they can have different names?

## shibo — 2026-10-10T04:40:59.219000+00:00

Ill look into it

## Seve — 2026-10-10T04:41:10.597000+00:00

hmm you're right!!!

## Seve — 2026-10-10T04:41:18.772000+00:00

i'm not sure why it's doing that but it's concerning

## Seve — 2026-10-10T04:44:42.279000+00:00

do you have a multi-color led on this

## Seve — 2026-10-10T04:46:47.321000+00:00

this one is pretty small https://jlcpcb.com/partdetail/XL-1615RGBC-2812B-S/C41413180

## Seve — 2026-10-10T04:47:29.168000+00:00

i think that's the only major thing. It's really easy to plug these in wrong so i'd be worried if we don't have a way to somehow tell the user something is wrong, also you can't give feedback on temperature, can't debug etc.

## Seve — 2026-10-10T04:48:38.434000+00:00

bad pins on the bottom, something to look into

## Seve — 2026-10-10T04:51:05.862000+00:00

i like this board, i think it's coming together, i think it'll sell a lot

## Seve — 2026-10-10T05:01:15.504000+00:00

<@778624824875941908> the nema8 is the perfect motor to have for controlling the probe depth

## Seve — 2026-10-10T05:01:27.051000+00:00

people put linear actuators onto them

## Seve — 2026-10-10T05:01:36.728000+00:00

amazing form factor

## shibo — 2026-10-10T07:24:19.756000+00:00

You'd have to pre-order from the tscircuit store

## shibo — 2026-10-10T22:18:44.547000+00:00

<@757706909351411845> I do use a led and a temperature sensor, and the 3d model issue I fixed earlier in core but it's version is stale in the website, I also fixed the net names in the pcb

## Seve — 2026-10-10T22:25:03.864000+00:00

ok let me know when/what i should review

## shibo — 2026-10-11T04:07:14.724000+00:00

## shibo — 2026-10-11T04:07:32.682000+00:00

Last time you wanted to review the jst connections

## Seve — 2026-10-11T04:08:49.188000+00:00

the led has some courtyard violations that aren't being captured, idk if the 3d model is accurate but i don't think so

## Seve — 2026-10-11T04:09:15.809000+00:00

<@778624824875941908> did you check that the jst connections are identical to Rishabh's-

## Seve — 2026-10-11T04:10:45.652000+00:00

maybe you should review the warnings
Attachment: CleanShot_2026-10-10_at_21.10.342x.png — https://community.tscircuit.com/media/1558693315699015791

## Seve — 2026-10-11T04:11:15.237000+00:00

i would maybe even try to get to 0 warnings because that's just generally a good criteria to have, and it would have cought the LED bug above

## Seve — 2026-10-11T04:11:36.695000+00:00

also if there's a bad warning, this gives you the opportunity to do a fix for it

## Seve — 2026-10-11T04:28:35.420000+00:00

i'm very excited for this board btw

## shibo — 2026-10-11T04:28:44.825000+00:00

Cool
