Can’t Upload a dxf File Created with QCAD CAM Pro to Internet Machining Sites

[dxffan]

Hello everyone. This is my first posting to this forum. I recently purchased QCAD CAM version: 3.28.1.0 with the goal to have a dxf file uploaded to CNC machining sites for manufacturing. The detail I need comprises a closed path C-Channel Aluminum track. I’m attaching herewith the ClosedTrack.dxf file I created with the help of the aforementioned QCAD CAM program. The drawing represents only the needed three tool paths, all the rest of the CAD details omitted. It is presumed that the Aluminum slab of the raw material is of perfectly parallel top and bottom surfaces. Also, because the QCAD CAM program doesn’t seem to have a way to indicate the thickness of the raw Aluminum slab, the latter must be of 0.75 inch thickness to begin with. The thickness of the raw Aluminum piece being 0.75 inch, the first trajectory carved (the middle trajectory) would require the milling tool to go as deep as 0.625 inch. This allows for a quasi-3D tooling. The other two trajectories of the tool (the outer and the inner) require the tool to carve the Aluminum to a 0.75 inch depth from the surface accepted as the 0 level. This would allow the inner part and the outer part of the raw material to be removed and as a result a closed 0.75 x 0.75 inch C-Channel to be formed with three 0.125 inch thick walls. I’m trying to upload the described ClosedTrack.dxf diagram, also attached herewith, to various internet CNC manufacturing sites to no avail. Could you advise please what should be changed in order for the drawing of the detail described to become acceptable for manufacturing by CNC machines?

Hi, welcome to the QCAD community.

I’m trying to upload the described ClosedTrack.dxf diagram, also attached herewith, to various internet CNC manufacturing sites to no avail. Could you advise please what should be changed in order for the drawing of the detail described to become acceptable for manufacturing by CNC machines?

This drawing is not really a drawing. It contains only QCAD/CAM tool path information which can most likely only be read by QCAD/CAM. If those CNC manufacturing sites do not work with QCAD/CAM then they can't read your drawing.

Common praxis would be to provide a real drawing or preferable a g-code.

Thanks for the welcome and for the answer. The g-code generated by the QCAD CAM program for the model ClosedTrack.dxf presented in the OP is:

N10 G0 Z25
N20 G0 X3.2135 Y-2.3938
N30 T1 M6
N40 S2500 M03
N50 G0 Z2

N240 G1 X3.2135

Will the above, saved as a file with extension SAT, be an acceptable code for a standard CNC machine to produce the detail at hand?

There are many dialects of G-Code, normally we use a specific postprocessor that is a match with the CNC driver.

Just present the outline drawing to your CNC manufacturer.
Or you need to know what specific G-Code dialect that is required.

The G-Code sequence you provided is pretty basic, so yes but maybe no.
