Fusion 360 GRBL post update for v1.1

(William Adams) #1

tklus over on the Shapeoko forums asked:

please vote this up guys so we can get the post team to make the changes to support GRBL v1.1 laser modes.

(and presumably the balance of Grbl 1.1?)

I was just about to post something on this…uh…post (processor). I followed your link, @WillAdams and it turns out that the status was changed to “Implemented” on 3/3. I just downloaded it and am going to have a go. Here’s the page with the dl link for anyone else out there that might be interested:


I just added a 5.5W Ultraviolet laser to my S3XXL last night, so this is an incredibly timely update.

So far not so good. I’m having trouble finding an operation that the PP supports. Here’s the output:

Still no luck getting that post to work. Has anyone else had an opportunity to look at it, or maybe know what kind of operation other than a “Milling toolpath” it might expect from F360? I’m trying out the Smoothie Mill/Laser post for the time being, and did get a successful etch, but the files are requiring a bit of cleanup before running them.

Update: I may have answered my own question regarding toolpath types in that I don’t think I have waterjet/laser support enabled in Fusion 360. I’ll report back.
