Rapid movements for Fusion360 gcode script

[ghf20]

Hi all - new to the community but have been machining some cabinets with my LR4. I generate my Gcode with the Fusion360 Grbl Post processor and was frustrated to find that Autodesk removed yet another feature from fusion, the rapid movements.

If you parse your gcode you’ll see this message:

(When using Fusion for Personal Use, the feedrate of rapid)

(moves is reduced to match the feedrate of cutting moves,)

(which can increase machining time. Unrestricted rapid moves)

(are available with a Fusion Subscription.)

So i wrote a script to re enable rapid movement in fusion generated gcode. Check it out, but i suggest you view it in NC viewer before running the gcode on your LR!

Love those first posts. Coming in with a solution instead of a problem. Welcome!

Heck yes!

@ghf20 Welcome to the V1 community forums. We’d love to see pictures and details of your LR4 build as well as the cabinets you’re making.

This is definitely an issue with the Personal Use license (that and not being able to export bodies or projects as DXF files). It is their way of getting you to shell out the big bucks for a full use license.

I love the script! Can you do something similar so that free Fusion will output DXF?

Just checking you’re aware - you can save individual sketches as dxf from their right click menu.

Yup, sketches can be exported directly as DXF in the free version.

I was trying to export complex faces made up of multiple sketches, with features applied to the bodies that didn’t appear on the individual sketches.

I did find a work-around (thanks @azab2c) by selecting the face I wanted to export, and using the “project” feature to create a sketch based on that face. Then I used the Export DXF option in that sketch menu.

Yeah that’s what I do too. You can also use joints to layout bodies on a ‘sheet’ then do the project to an offset sketch to make the dxf. I was pretty sure you knew that but just didn’t want to assume in case I was wrong.

It costs $25 but the Mapboards Pro plugin made DXF exports a lot easier.

A week ago, my wife sent me a couple links asking if I could make one of these. Now that I have a LowRider, this was much easier and turned it around in a week, which is dramatically shorter than normal. Still needs a finish applied and some grip tape, but it’s otherwise complete. There were some angles that I cut on my table saw. [20240204_165334] I didn’t even know what it was. Apparently, it’s for stretching and helpful for foot pain, which makes sense since she’s a runner. Here’s a v…

I am pretty sure the flyfisher post processor also does this, or at least did that. I’m not being disrespectful, I just want you two to collaborate if it makes sense.

Thanks for the contribution!

You’re right! It definitely does, i hadn’t seen that project.

I’m also working on a a leveling mesh z modifier as i can’t seem to get my spoilboard perfect. It’ll act like a mesh bed leveler that exist in the prusa mk3s+ 3d printers but with the touch plate instead

can’t seem to get my spoilboard perfect.

Is that after facing it with the CNC itself? Because that should result in a surface that is perfectly level to the X-Y motion of the machine. It may have small ridges if the spindle is not well trammed (perpendicular to the spoilboard). This Spetool bit is amazing for facing. Link
