Spindle does not start - Fusion Post-Processor generated Gcode

Veröffentlicht von: @memxcell

I have an M700 with the AMB 1400 FME-P DI spindle.

I am using Fusion 360 to create my design and the UCCNC postprocessor to export Gcode (.nc).

 

When starting the job the spindle does not turn on - I have to do this manually using the button in UCCNC.

Sometimes the spindle stops mid job, e.g. in case of a tool change and does not escape road - with several broken endmills as a result...

The Fusion Post Processor generated Gcode contains the following for setting the speed and starting the spindle:

"S5000 M4" or "S9000 M3"

I have found if I replace e.g. M3 with M03 it works and starts up.

 

- Am I missing something in my Fusion 360 or UCCNC setup or can I fix the post-processor such that I do not need to edit all Gcode files?

Thanks for your help

Hi,

In the post file, look for the spindle start section (usually under onSpindleSpeed() or similar) and change the formatting of the M-code to force two digits. That way, every exported file will be correct and you won’t need to manually edit G-code again.
