Postprocessor 3D printing

I have used Fusion 360 and Postprocessor for Anet A8 for years with very little trouble. With new 3D printer Flash Forge Adventurer 4 it is trouble. When filament should go out it goes in. Motor runs wrong direction. Same component is used for both tests. What is wrong.

Hello @fjellang 

 

this is strange.

I don't really see a reason for this behavior, can you share the gcode generated by Fusion?

Looking at the code, I may find a cause.

 

Regards.

Hi @fjellang 

 

I looked at the file, and i did not see anything shocking.

The E value seems to be correct. There is some few value negative, But it's always E-0.5, the small retract before a skim moves.

So, nothing strange.

But you can try by switching to absolute filament mode by unchecking a switch in the post properties:

Can you try to generate a gcode in absolute mode and test on the printer, please?

 

Regards.

Hi @fjellang ,

 

So that we can also get relative extrusion working for the Flashforge printers in the future, could you please assist use with testing the following gcode file.
The ONLY change that has been made form your original file that you uploaded here, is that the 'M83' command has been placed after the 'G90' command:

 

M83CommandMovedToAfterG90.png

This is because we believe the G90 command was overwriting the M83.

 

I attach this edited gcode file to this message.

 

Many thanks for your help!

Hi All,

 

some posts had been modified to avoid this issue.

The Dremel, FlashForge and Re3D posts are now fixed and available online.

 

Thanks for reporting the issue and help us test and validate.
