NC Program Post Process Issues

[mpm136]

Hello all,

I am attempting to use Fusion 360 to create G-code for additive manufacturing. The NC Program that is created from my toolpath does not at all match the toolpath. Regardless of the toolpath, the g-code only contains one small straight line. Can anyone provide any insight into this issue?

Hello @mpm136 

After creating a setup, selecting a machine configuration file, then a print settings, have you selected the body to slice at the bottom of the dialog?

Then have you right clicked on the toolpath, and generated it ?

Are you able to simulate the toolpath by right clicking and selecting the Simulate option?

If you want others to be able to help you analyse the issue, you should share the file you are working on.

You can either share a link to your Fusion file.

or you can save an archive and share it on the forum

Have a pleasant day.

Cheers

Thank you for the response. I have done everything you have mentioned, but Fusion 360 crashes when I try to simulate the toolpath. I have shared the file I am referencing. Any help would be greatly appreciated.

Hello @mpm136 

i suspect this is due to the size of the shape.

It's only 0.01mm thick.

I have asked the developers if something this small can be sliced by the algorithm.

Hi @mpm136 

after looking closer to the issue, here is the cause.

How do you want to deposit a shape that is 0.01mm thick.

with a nozzle which has a 0.05mm diameter?

It's impossible. The nozzle is 5 times bigger than the shape.

Cheers

Hi @mpm136 

and the print settings are worse.

The extrusion width is set to 0.3mm, so 30 time the shape.
