Hi, I am a newcommer to Fritzing. I have a PCB that just won’t export the drilled holes.txt file. I built the circuit in the schematic view (kinda just how i understand EE) and when i went to export the file (after auto routing) it doesn’t export the drill.txt
I am using a custom Cherry MX switch that is supposed to have all the holes pre-determined
i am very confused as to why this would happen
Keyboard2.fzz (58.3 KB)
Works for me on Fritzing 0.9.6 on Win 10. You have a large number of DRC (routing->Design Rules Check) though although that isn’t affecting the export.
Gerber output of top, bottom, silkscreen and drill layers from gerbv:
Only drill and silkscreen
It would be a good bet to check the drill hole sizes though (and fix the trace routing til DRC passes!)
Peter
huh, that is very strange why its working for you!
i’ve tried on many different basic files, and i think its my program and not the circuit
i would ask for the drill.txt file, but that seems like an uncool thing to do 
Thanks anyway!
I do not know if this is the cause, but the cherry key part in your sketch has some errors.
There are others, but more cosmetic.
What operating system and version of Fritzing are you using? The gerber export works for me as well using Fedora 33 and Fritzing 0.9.6. I get at drill file
ls -1 ~/Downloads/tmp/
Keyboard2_contour.gm1
Keyboard2_copperBottom.gbl
Keyboard2_copperTop.gtl
Keyboard2_drill.txt
Keyboard2_maskBottom.gbs
Keyboard2_maskTop.gts
Keyboard2_pnp.txt
Keyboard2_silkBottom.gbo
Keyboard2_silkTop.gto
oh dang
im using Windows 10, Frizting 0.9.6
considering that others can export the files and I cannot despite having the same system (I cannot export drill.txt in any circuit) I think its safe to say its my program that is messed up
As am I. Here is the drill.txt file:

and the gerber output directory:
I’d suggest reinstalling Fritzing as it looks like the gerber output processing has gotten corrupted somehow. I can also clean up the custom parts which should fix some of the odd drill sizes.
Peter
oh my god thank you so much!
a clean install is something i may just do
thank you all again!
You likely need to check the DRC output too. It is reporting that some of the traces are too close and/or overlapping which can cause problems on the board. As well I made a part for someone last night for sockets that fit the MX2 keys (available from Adafruit) that you may be interested in.
Peter
Actually you need to replace the Cherry switch part with this one:
Cherry MX Keyswitch Simple-improved.fzpz (5.4 KB)
You will need to delete the current part (delete minus will delete the part but leave the traces) in every where, then shutdown and restart Fritzing to actually delete the part before it will let you load the new one. The original part has holes that are too small: This is the data sheet for the Cherry MX from Digikey with the recommended PCB layout. As you see the holes in the original part are too small and the key isn’t likely to fit.
The improved part has correctly sized holes:
Peter
Thank you so much! My PCB is now into production at JLC, and soon enough Im gonna have a cool keyboard for a cyberdeck!
Thank you so much once again!
