WARNING! (@John_Pateman) You screenshot shows “Use extended X2 format…” + “Include Netlist attributes” + “Disable Aperture macros…” checkboxes set in such a way, that contradicts this: Post-v5 new features and development news - #333 by eelik post.
I always set these three checkboxes according to the link above and have no problems. Actually, I have made a mistake with these checkboxes (don’t know how I configured them at that moment) a month ago and had problems with JLC:
- There were no thumbnail of PCB I am going to order, as usually is shown in their webpage (first bad symptom);
- Solderpaste (stencil) screenshots looked weird (flower-like pads instead of rounded rectangle pads) after JLC review, so I had to reorder JLC order with reexported gerbers with settings from the link above;
I think these settings are still problematic, and your screenshot should be updated in order not to cause faulty orders for users. Please excuse me if I am not correct.
I think this is a big issue (potentially causing reorders at the fabhouses), and should be clarified by developers, or JLC team…
Solderpaste layer, as seen at JLC with wrong gerber settings:
