Having trouble getting Gerber Drill.txt?

@hijackgmh

Did Export for PCB produce a drill.txt file for you? If so, then maybe it is a problem with my system or the download?

Yes the gerber export produces these files:

If your install isn’t doing so then there is something wrong. A reinstall may fix it I expect I haven’t heard of any problems with 0.9.10 on the Mac (and a check of issues on github doesn’t show anything.)

There is a problem with the cpu part though. It has no pads on the pcb so you will only get holes (indicated by this in the drill.txt file)

The T1 indicates a non plated through hole which is why it is hole only (the holes are also too big at 0.044in they should be 0.038 for 0.1in headers.) I’ll correct the part and post it in a bit. Here is the hole problem note no pad around the hole.

edit: well that was easy I apparently already did this in this post

Yes, the problem is that you need to change the drawing units from px to in. As part of that Inkscape redoes all the internal sizes. I don’t know of a way to do that in Illustrator, reading their documentation I’m not sure it is possible (although Illustrator appears to process a svg that is dimensioned in inches just fine.) They seem to think they know best and you should just use what they give you (although there may be some way I don’t know to set the values as well.) Here is a fixed up ver…

Amica NodeMCU DevKit 1.0-improved.fzpz from that post is the corrected part (it still needs the mounting holes replaced by holes though.) If you use “delete minus” to delete the part that will leave the traces connected. When you replace the part you then need to click on the end of the trace and drag it on to the pad on the part to remake the connections (unfortunately in all three views though.) I sometimes find it easier to just redo the traces.
