Settings to cut 3/4 metal

But that is likely set by your default lead-in, lead-out rate as it can be set up as a percentage of your cutting feedrate:

So it could be dropping to 60% but I think it might be because of this menu/tab.
(Unless you are saying it is dropping 60% of what you set in the Lead-in/lead-out. In that case, my information is suspect.)

This is the difference of 0.025 cut height. Same speed. Bottom one trash the nozzle in less than 5 in.

Should have been .1, set at .075

Note the dross. Bad cut height evil nasty dross that barely breaks off with a chipping hammer. Proper cut height is minimal dross and flakes off real easy.

1 inch plate, 80 amps. 5 in per minute cut speed.

Does Fusion360 have the wiggle pierce option lke SheetCam? It makes a huge difference when piercing 1/2 plate with a 65sync.

I am thinking no. Never heard of it. Might be able to do a helical pierce though. Have to look into that.

I wonder if a pulsed pierce might work as well. .5 seconds on, .5 off.

I accidentally started a cut yesterday that was supposed to be a dry run and it shot a good .2-.25 into the plate.

No. That suggestion came up about 6 months ago. Sadly, no “wiggle” in Fusion 360…yet! (Ever so hopeful of some additional CAM abilities :roll_eyes: :slightly_smiling_face:)

And what else has come up before in the forum is if we want these features we have to start asking Autodesk for them.

https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/How-to-submit-a-product-enhancement-idea-for-Autodesk-Fusion-360.html

We as a forum group of 10,000 members could probably spam requests at a high rate and potentially get them to change things.

The link above provides you somewhere to request.

Every time there’s a product feature that’s missing request it.

This is a squeaky wheel gets the grease situation.

@Elsierdguez1 - any progress?

Sorry I’m very new to this and confused honestly haha I’m setting the tool in the library and trying to figure out this part

Well it won’t let me upload pic but pretty much what to insert ont he process inputs were running off 220 voltage in our shop

@langmuir-aksel - Can we get @Elsierdguez1 account bumped up to upload pictures?

I just bumped @Elsierdguez1 by one trust level, which should give the necessary upload access- try it now!

None of the “Process inputs” pass through to the post processor. You can enter them so you can reference to them if you want.

Cut power: set at your plasma cutter (value set here does not mean anything to the post processor)
Pierce power: same as ‘Cut power’ as it is set at the cutter
Pierce time: this will be entered in the Post Processing screen. Enter it here just you remind you what it should be.
Pressure: set at the cutter. Some cutters like Hypertherm, regulate this pressure automatically.
Assist gas: same as this item is not used by the post processor, it is only for reference the way things are set up.

So basically in the tools for Fusion 360, you only need to give it a name then give these values, as a bare minimum:

  1. Kerf width
  2. Feedrate

When you get to the post processing screen, you will enter:

  1. Cut height
  2. Springback
  3. Pierce Delay
  4. Pierce Height
  5. And check IHS and/or THC

Thank you that’s helpful

I purposely left out a few things but it will work with those bare minimums. And trust me…it was very confusing to me as well when I started.

Along with kerf width (in tools) you will see an option for “nozzle diameter”:

Some people put 1 inch because that is closer to the actual size but many of us just use the kerf width as it helps you visualize the simulation better.

Thanks again! I’m going to attempt to cut the 3/4 plate this weekend let’s see how it goes :rofl:

Good luck. You have a great attitude to learn this very fast. Here’s my tip. Make sure your water table is full. The slow travel speed will damage your machine. The air pressure will push out the water from under the metal and cut a hole in your tray.

Forgot that part BigDaddy. I will probably never cut 3/4" thick metal, but I can imagine that this would/could happen.

I ran my 100a, water at the top of the slat holder. It for sure blew the water away, but did not puncture the pan. The seam however did not take kindly to the low level. Fill the water to 1/2 to 1/4 inch from the top, keep a mop handy.
