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.

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.
