What does your PCB look like when you view it in the Gerber Viewer? Did you create new Gerberfiles after KiKit?
Also, your Panel does not look like it’s going to be manufactureable. It is probably too weak, and will break apart in the machines during production. Maybe you can leave the panelization to JLC. They have some extra settings on their website to let them do the paneliziation.
I have not used KiKit, but if you have gerbers, you can open them in a Gerber viewer. Either directly in KiCad’s own gerber viewer, or with any of the online viewers.
You don’t create Gerber files using KiKIT. KiKIT only creates a panel for you.
You open the created panel PCB in the KiCAD PCB Editor and export Gerber files from there (or if you use one of the JLC plugins - you can export it from there).
I use the same method as you and never had any issues.
Perhaps it’s just a JLC viewer not showing correctly?
I’ve noticed it’s sometimes not accurate. Are you chooses PCBA as well? If so, then the preview there is usually correct.
Alternatively check in another Gerber Viewer. If shown all good there, then speak to JLC support chat.
I’ve never used JLCPCB plugin but I’ve used KiKit without problems. In your point 8) just generate the gerber files and then send them to JLCPCB. I suggest you to ask JLCPCB support if needed.
The steps @Stealthrt listed above look correct.
I use both (KiKIT and JLCPCB plugin) with no problems following pretty much the same steps (except my own KiKIT panel configuration).
I’d check first how the panelized PCB looks in alternative Gebrer Viewer (no KiCAD and no JLC). If all looks correct, then upload as a new order and speak to JLC support.
If doesn’t look OK in the Gerber Viewer then think how to solve it in KiCAD / KiKIT / JLC plugin.
Remember it’s not necessary to use the JLC plugin to submit jobs to JLC, it’s just a convenience. People have been generating the manufacturing files by hand and zipping for ages before JLC provided a plugin. So you should work out on where KiKit left its output.
Agree. However it’s a great convenience, especially for PCBA. Just a couple of clicks and it’s done
BTW. That plugin is not provided by JLC. I think there is one provided by them, but this one is from the link below and it’s really good:
