Gcode from fusion has stopped working

Snapmaker 2.0
1

I’ve just done a design in fusion360 for the first time in months! it creates the gcode, it loads into luban, it transfers to snapmaker2, it runs the boundary.

When i hit start the bit starts spinning but it doesn’t move. when i try to stop it it just stays spinning so i have to power off.

i tried running an onld file that was already on the machine and it ran it fine. so it seems to be something new or new with fusion as i havent used the cnc for a few months now.

i compaired the 2 fgcode files but i dont know what im looking at!

heres a snipet of the gcode:

Never be aware of this :open_mouth:

They changed things a while back to basically make you pay for a subscription by taking lots of the bits out of the free version. Not sure if this is what’s causing my problem as i haven’t used fusion to create a design for a while.

4

Parens are not valid comments in the Marlin gcode flavor. Comment lines need to start with a semicolon.

Are you using the correct post-processor? Parens are used for comments in GRBL, a different gcode ‘language’

Edit: Not that invalid comment delimiters “should” cause a problem, they should be ignored. However, I have seen people mention invalid gcodes can cause a freeze depending on if it’s being run through Luban or the touchscreen.

5

When i hit post process it does say snapmaker marlin in one of the boxes. cant work out how to add a screenshot here.

6

If the bit spins up, it’s processing the M3 command, but apparently not anything after it. So that multiline comment might (ridiculously enough) be the problem. Or it might want “M3 P100” instead of plain “M3”, although the short command is supposed to be valid (ref: Spindle CW / Laser On | Marlin Firmware ).

7

I just deleted the part in brackets so it runs straight from M3 to the lines of code but nada still not moving after the bit starts spinning.

8

So i figured out the problem after a few goes at eliminating possible causes and it was… I had to download the configuration files for fusion360 from snapmaker as it seems they’ve been updated since fusion decided to change what comes with the free package! I don’t remember seeing or hearing anywhere that this needed doing!

SOLVED Anyway :smile:

The configuration files haven’t changed from what I installed in July.
Must be something else. Glad it’s working.
