Robert,
Thank you very much for the correct answer to my previous question "Text window too small etc"on july 20.
I set the text on Vector and it succeeds indeed. I also placed the window in layer 41 tRestrict. However the machine not mills the copper around the text. He engraves only the rectangle around the text. But this will be a machine related problem I think?
Now I ran on against a new problem.
My CNC machine (Collinbus PCBbox of the firm Belgium) can not process the Excellon file build by the Cam function in Eagle.
I got the following info from the engineer of Colinbus
1 There is too little information in the header.
CNCsoftware displayed the following warning : Warning: "Filename. drd is not Format2 file. Format parameters and/or tool sizes might need adjustment for correct import. "
2 The Filename.DRD fileheader does not give the right information the drills are expressed in mm while this should be in Inches (see header M72 indicates inch sizes). This will cause the drill holes unlikely great.
I got this message from my supplier of the CNCmachine
Look at the header (which is by the way incomplete) and the tool list:
%
M48
- M72 ß-------------------- this command informs that the file is inch
T01C0.6096
- T02C0.8000 ß---- but tool diameters are defined in millimeters.
T03C0.8128
T04C0.9000 When M72 command is used then these diameters should be expressed
T05C0.9906 in inch!
T06C1.0000
T07C1.0160
T08C1.2192
T09C2.0000
T10C2.5000
T11C3.2000
T12C3.2512
T13C3.3020
%
T01
- X14099Y11281 ß---- coordinates are in inches
X17099Y13681
X16499Y15681
User should set following Format parameters in the Import parameter dialog:
Unit: Inches
Omitted Zeros Leading (this info should be in the file header but is missing)
Precision Format XY 2.4 (this info should be in the file header but is missing)
When file with this parameters is imported, the holes coordinates will be correct but their diameters will be huge since imported values for T1 to T13 are interpreted as expressed in inches not millimeters.
Also I discover a third problem probably related with point 1
3 The mounting holes of connectors and the self affixed holes are not drilled but engraved with a surrounded circle. And this is logic because they are not included in the Excellon file.
The DRD file is herewith included as .txt file .
How can I include all drill related info, within Eagle, into an Excellon file so that I get a good seamless connection with the CNC machine?
Can you help me here?
Thanks,
Jo Koene
