Starting this topic because its seems the CAM section is one of major struggles with Fusion 360 plasma user.
I’ll mostly be twitch streaming and posting below to start, until I feel the questions are hammered out. Then produced a more polished YouTube video using all the feedback gathered.
Came in about midway. Great idea. Thanks for the effort.
Lead-in/out decisions are a topic that I still struggle to understand. So many of the parameters are defined in a cut chart or machine specs, but there is some situational decision making to be done on the leads. I don’t yet have enough experience to deduce my settings.
Even though I’ve read a lot of threads where it’s discussed, it’s usually just advice about changing the parameter until it works. Not a lot about how to set it correctly based on conditions of the cut that make it critical to get them correct.
There was one helpful (to users like me) thread about cutting from the center of the hole. Maybe add that info to your video (apologize if it’s covered in 1st part of video).
I definitely want to go more in depth with some of the choices. How to treat holes is must. Normally with critical holes I’ll apply a different lead in like your link.
This video is more of an overview/starting point. over the next few weeks we can refine this presentation then produce a clean YouTube video as a “complete” guide
Thanks @TinWhisperer for this series. It is amazing what you do to help the forum members, me included. One thing I don’t understand. A bit basic, but confusing to me none the less.
Entry points for lead ins. Fusion seems to pick some very strange locations even though the parameters are far from limiting the choice. I try to change them and it won’t let me even with wide open space around with plenty of room. And also when I regenerate fusion entry points some of them seem to change location. I hope that makes sense. Hopefully at some point in the videos you can cover this
Ok I looked on youtube and see you have maybe 10 videos. One question that keeps bothering me is I see people use a tool path that goes over the top center of a piece they just cut out. I would rather go around any of the cutouts pieces so as not to run into them with the torch. I don’t have a machine yet but am learning how to do this.
With the THC I would still rather go around a previous cut out than over the top of it, just in case it pops up. I watch people cutting and they have to reach in to grab pieces that pop up. I have seen the “keep nozzle down” that does this on Fusion 360. But that wouldn’t make sense with THC.
I wish that function would exist also. When you read about the keep nozzle down feature it should work, you can set the distant and retract but it does not seem to update the toolpaths how I think it should?
Mostly post to twitch. I do need to spend some time to make some more polished videos for youtube.
Great I would love to see more of your videos. If you make another video is there any way you can zoom in a little more on the text in the dialog boxes? On my windows computer there is a magnify from the keyboard. Not sure if there is a way on a Mac, my iMac is 10 years old.
Also I find Fusion 360 not that hard to learn. 6 to 8 hours for the CAD portion. And the CAM is just setting it up just the way the Langmuir videos show. So I don’t even need to remember anything yet.
I am sorry to ask as I am not familiar with these twitch live streams: but are these available to view after the streaming is done? I have searched on Twitch and found your account page but it does not seem to have these videos.
I think I’ve made something like 80 twitch videos to date , I’ll have to take a look.
I do need to make some more focused clean content for youtube, I’ve been really checking out a lot of the new cam stuff from the last update trying to figure it out thoroughly myself first for making a video about it.
They definitely switched a lot of icons and combined a few tools.
And since the last update some of the sketch selection stuff seems to work a lot better and the tool paths seem to be developing faster
Thank you. As you might guess I have gone from confident to a bit anxious about the CAM issues. I have done fine for my last few pieces but they were small like the desiccant holder I put on FireShare.
So much appreciate your guidance and wealth of information.
Thanks for the clarification. Was it 14 days early on? That’s what I remembered and I searched your early posts before I replied and a couple of them you mentioned 14 days.
