Rapid speed feel slow (Full version)

Hey, I've been setting up some projects and there's some massive cut times. I have the full paid version of Fusion but either I'm remembering wrong, or the rapid speed is way slower than normal. Is there a spot in the program that I may have bumped a slider, or disabled rapids?

 

On the Linking tab of a toolpath, it's set to:

 

Retraction Policy: Full retraction

High Feedrate Mode: Preserve rapid movement

Allow Rapid Retract: Yes

Max stay-down: 32mm

Minimum staydown: 2mm

Staydown level: least

Lift height: 0mm

No-engagement feedrate: 1500 mm/min

 

 

Is it the no-engagement feedrate? I'd assume if there's no engagement it should just be moving at rapid speed, no?

Can you export and share your file?

What post processor are you using, and what is your machine?

Post processor is Grbl(Carbide 3d)

Machine's a Shapeoko (I've done cuts with rapids before and it seemed to be a lot faster) I read the machine can do 200inches per minute max, not sure if that's accurate.

I do tweak settings from time to time. It's also possible I'm going insane and rapids have always been this slow, but I doubt that's it. This is all on the simulation, as well. This isn't actually the cut, although I assume if on the simulation it shows it as slow, it should cut that slow too. Edit: It seems as though my rapids are set at max what my cutting feedrate is like I have the personal use version. But I don't. I can still post process multiple files using different tools all at once and everything that comes along with the paid version. Rapids just by default go the same speed I cut at. Once again, this is all in-program, so I don't think it's the post processor. (All that's applied at the time of post processing I assume). And when I post process and run the g-code, sure enough the machines rapids are the same speed as the cutting speed.

Also the material is MDF, if the cutting speed seems a bit high for a little hobby machine that's why

So before the updates that removed rapids from personal use, I was on a personal use license. I had one specific toolpath I'd always run. My boards are oversized by an inch so after a project I'd run this same file that'd cut them to the final size. (my projects are always the exact same outer dimensions)

 

It'd take like 6 passes but eventually it'd make it through, It'd cut along the top, then the side, then retract and rapid back really fast and do another pass.

 

After the update, of course the speed of that rapid was the cut speed, and it took forever.

 

I just re-made that same toolpath on a file and sure enough, on the simulation it shows the rapid moving at the same speed as the cut, incredibly slowly. So it must be an option somewhere in the program that's not allowing rapids (or the speed of them is set low). I can't find any info anywhere on where you can set the rapid speed.

The simulation speed is not supposed to be real time, nor does it change between rapids and feeds

The toolpath display is:
Red: Plunge

Blue: Cutting

Yellow: linking/rapid moves.

 

Can you share your latest file AS WELL as the NC code you posted out?
