Double tool path in the conversion from dxf

[Roberto Arrigoni]

good morning.

When I try to convert a simple rectangle (side 50mm) created with AutoCAD, dxf2gcode a double path for the creating of the rectangle.

When I open the gcode i see who created twice the instructions to create the rectangle.

I checked that I have one layer, and the lines that create the rectangle are singles.

Has anyone ever encountered such a problem?

Hello.

This Is not a Problem, thats by Intention. Please check milling and slice depth. If slice depth is smaller then milling depth more then one path is created. Regards Christian

Hi, thanks for the help.
I have modified the values in config file and now work correctly. Thanks

Hello there, do you have the values that you used? I am having the same issue but I can't seem to get the numbers right. Thank you

[Christian Kohlöffel]

Please tell us the parameters you use or send a screenshot.

Hello Christian, 

Here are both parameter and settings files that I am using. I have messed around with the values, and I seem to have made it work, but I am not sure how I did it! I tried again with another drawing and I am getting the same issue.

I have not understood completely what the depth values mean in terms of lathe. As I am understanding it, that is the distance from edge to edge of a cut?

Thank you for your fast response!

Hi Guglielmo.

This program was created for working with CNC. 

On CNC machines is necessary set the working depth (axis3_mill_depth).

So if you want to get a groove of 2mm (axis3_slice_depth) and you've set to a depth of 1mm machine processing (axis3_mill_depth).

The program will make you a double path, because to get a depth on your piece of 2mm the burr must pass twice removing material (1mm) for each pass.

If you use a laser cutting must set the same values for

axis3_mill_depth

axis3_slice_dept

So the laser will only make a path.

I send you my config, if you any problem send me a mail.

Can I ask if you are using a laser cutting?

The machine was built from you?

Thanks a lot

[Guillermo Vargas]

Hello Roberto,

Thank you for your response! It is now very clear to me thanks to your explanation. The machine is an industrial size plasma cutter but I think it can be assumed that it is a laser cutting. I did manage to make it work and that probably was because I set the values correctly by accident.

Also thank you for sending me your configuration. You have helped me greatly!

Hi Guillermo

The pleasure was mine, if you still need help let me know

See you later!

Hi guys i am new to gcode. I own a cnc plasma and i face the exact same problem. Every shape i design, i see the code two times. I read the conversation and set the two values having the same number.

axis3_mill_depth

axis3_slice_dept

I still get two paths. Is there anything else?

Is there any other ideas about this or i ll always have to delete manually the second path, because in designgs with lots of elements (squares, curves) its not easy and it's always a chance to make a mistake.

Thanks in advance

[Christian Kohlöffel]

Please try other combinations of slice and mill depth. Use a higher slice depth and try again.

Regards Christian

J'ai vérifié que j'ai une couche, et les lignes qui créent le rectangle simples.

Quelqu'un at-il jamais rencontré un tel problème?
