Personal Use version takes away rapid moves and makes my Carbide 3D post not work

[Anonymous]

Hi, I am new to Fusion 360 and trying it out via the personal use 1 year trial.

After posting to the Carbide 3D config, I see this line noted in my .nc:  "(When using Fusion 360 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 360 Subscription.)".

Then, when I try to run the .nc on my router I get the following error before any motions happen: "GRBL Error: Undefined Feed Rate".

I understand there are limitations to the free version, however in this case, the limitation removing the usability. I know this should work on the carbide 3D because I exported avery similar .nc program on my friends student version of the program the other week. 

I have two questions: One, is this a bug that was introduced with the new personal use limitations?

Two, is there a way to modify the config file or my operations to get around this??

I found the detail in the .nc that crashes when I try to run it in Carbide Motion. For some reason Fusion 360 place lines in the code that said G1 X10 Y20 F0  <--- since the feed rate was zero it was yelling at me.. Now I need to find out why fusion was outputting gcode with F0...

Why would the update do this??? It crashes my program. Please help me fix this?

I found that just removing the `(When using Fusion 360 for Personal Use, ...)` comment from the file fixes the problem.

I would guess that there is something in the software toolchain that can't handle very long lines.

Not sure if this problem is in the GRBL software on your host computer, or if it is a problem in GRBL firmware on the control electronics.

In either case, Autodesk could resolve this issue by splitting the long comment into multiple lines of shorter comments.

Hint, hint...

Yeah, this is a known bug that we'll be fixing ASAP. Apparently, the GRBL doesn't support lines longer than 70 characters (which includes spaces actually)

Hi @seth.madore  and @markSJVQS, in this case I modified the g-code line by line and found that the F0 was what was crashing my program. I cannot find why the drill commands would be creating the F0 feed rate.

@seth.madore, I found that the removing of rapid commands is a new limitation for the personal use version of fusion 360. Is there any chance that Autodesk might add it it back in?

FYI. My post was locking up right at the start. Deleting the comment allowed it to run halfway through the program before locking up again 😞

Oh, I see it now. The comment is added before each section. Yikes.

An update when out a few days ago to address this (and other) issues

This tool combines multiple .nc files and removes the speed limitation on travel moves.
