Moulding toolpath - CNCnutz Episode 232

[@DaveGatton]

Great video Peter! I was waiting to see Chip make an appearance at the end dancing to the CNC "music". :-)

[@cncnutz]

Thanks Dave. Didn't think of that. Cheers Peter

[@mestevep12]

Thank you Peter...I have learnt something new today !!!!!..love the music by the way !!!!

[@cncnutz]

Thanks Stephen

[@JodieDavisCuckooClockArtist]

Exactly what I needed to figure out how to cut siding for a retro RV cuckoo clock I am designing. Came out beautifully on the first try. Thank you!

[@cncnutz]

Thanks, glad it helped. Cheers Peter

[@SimplyWoodenCreations1980]

Thank you Peter so very much for helping me out. I was able to make the lid... it worked great. I will be posting pictures soon.

[@cncnutz]

Thanks Russ. Look forward to seeing the final result. Cheers Peter

[@georgejaxxin4957]

you're a star, i have been messing with this for ages , great stuff thanks

[@cncnutz]

Thanks George.

[@jamaljundi8125]

Great lesson.I always enjoy your videos.

[@cncnutz]

Thanks Jamal

[@peterrenner8519]

You have moved to the big time with Aspire and the help from Vectric. You deserve the support from such companies. Your work has been consistently helpful for many years.

[@cncnutz]

Thanks Peter. Much appreciated.

[@wallystoolshed7050]

Im doing the same thing, but want to remove the bottom side as well leaving a quarter inch thick lid. How do i do this

[@derekjenkinson8014]

Two layer job, on the reverse layer I would invert the curve and adjust the z to get the inside curve.

[@MegaTopdogs]

Nice video Peter Thanks

[@cncnutz]

Thanks Geert and congratulations on reaching 1000 subs. Cheers Peter

[@104Tomcat]

Great job as usual Peter! Easy for me to understand. Now I know how to make the lid for my pirates treasure box, do you have a tutorial on How To Fill Said Box? Thanks!

[@Simsy5861]

Hi Peter. Love your musical efforts. Very interesting video and it made me wonder if one could create a dome using this method, perhaps by creating an arc in the X direction and one in the Y direction. Any ideas about that? Also, could one do V Carving on the resultant surface? If it can be done, I'd love to know how. Cheers

[@cncnutz]

You can easily create a dome or even a dish but you can't engrave on it s it isn't really a modelled surface. Cheers Peter

[@neatpleats11]

Hello Peter, now that you have made the lid, can you now add a pattern to the top?

[@cncnutz]

Not with this method Scott. You would need to model it in 3D. Cheers Peter

[@jims11762]

I believe you get more control creating your lithophanes with Aspire. What material are you using for your lithophanes? I know your no expert at Aspire and to be honest I like that, because it brings up different ways of doing things. Great video.

[@cncnutz]

Thanks James, your probably right but I'm using PhotoVcarve because I have it and because many can't afford Aspire but PhotoVcarve will get them up and cutting. It was the first Vectric software I bought. The plastic is Cast Acrylic and is white.

[@WoolsonSoundcraft]

Can I make a 3d component from a molding tool path? I want to project a profile along a molding path but can't figure out how to do that.

[@ChaosOptional]

Hello Peter, you can use the extend tool to extend the arc... quick and painless...

[@cncnutz]

If there is a long painful way of doing something I will usually find it. I will look into the extend tool. Thanks.

[@ChaosOptional]

@@cncnutz You are welcome!

[@LPRNChannel]

Yes you can extend in small increments like this but keep in mind that vcarve does not really extend the Arc... it adds a straight vector tangent to the Arc to the boundary you select for the extension.... little thing but worth mentioning.

[@woodbe5311]

Hi Peter. Im a folower of your videos and thanks for sharing all that knowledge. im trying to molding a piece of MDF 1300 x 130 x 12 mm cambered along 1300 mm to compensate a slightly wall curve i have behind a shelve im trying to put on that wall. Can you help me hot to create a toolpath for that propose. )using Aspire here. thanks

[@RajkumarSingh-IND]

Hurray!!!! First Comments. Thanks, Peter PAssuello, good video

[@cncnutz]

Thanks Rajkumar.

[@loskop100]

I can't afford Vectric but in Cambam I extrude the arc as a solid and draw a rectangle for a selected shape boundary and get the height of the sides by leveling the top when I turned it over to do the inside. A projected line from the rectangle to the surface gives a toothpath for a bevel cut around the edge. Then while you are at it you can project whatever engraving on the top, in my case it was the entire crew of the Paw Patrol.

[@cncnutz]

Thanks Loskop. Sounds great.

[@loskop100]

@@cncnutz I just had another play with it and when creating the solid give the upstand sides a 1 degree slope and the toolpath will go over the edge and down to the table.

[@pwrouzaud]

Peter, the music was great. I wish I had the score for the ukulele so we could jam in a play along. Peter

[@cncnutz]

Maybe we could start a band.

[@IH1940HAY]

Did you say this could be done VcarvePro, How? Thanks

[@cncnutz]

I did say you can do it in VCarve. If you want to use VCarve just follow the video. It shows you how. Cheers Peter

[@johnbourg3388]

Peter, why not just use the Boundary Offset? Set to .125" (half the diameter of the cutter) to remove the lip.

[@northotagogolf]

That's what I wondered..

[@cncnutz]

I haven't tried it yet but I think the boundary offset will screw up the top of the curve since the cutter would be 1/8 above it. I will test tonight. That said the extend line feature sorts it in 10 seconds. I will do an update. That's what I like about this hobby. There always something to learn. Cheers Peter

[@johnbourg3388]

@@cncnutz Nope it doesn't effect the top of the curve. Easy test, set a 1" boundary offset and preview the toolpath. Only the ends "boundaries" will be effected.

[@cncnutz]

Very nice. I will definately play tonight when I get home. Cheers Peter

[@cncnutz]

Well I tried the tool and it is the clear winner followed closely by the extend tool. I can see this being very useful in the future. Thanks for the heads up and i have just realeased an update with your suggestion shown. Cheers Peter

[@michaelg6586]

That must be an old video of your CNC singing. Still has your old router on it instead of the spindle.

[@cncnutz]

Yep. Sure is, but is seemed like a good excuse to use the pirate theme.

[@666Azmodan666]

a lot of work in addition not precise. Can not I just check the R of the arc in this program? Draw a full write in a rectangle and cut what is sticking out, without measuring and perfect width. Work for about 10 seconds.

[@cncnutz]

There are multiple ways of doing it and mine is probably not the best. I'm told there is an extend tool I should have used so I will be investigating that option. Cheers Peter

[@paulreader1777]

@@cncnutz I am sure the extend tool has done a good job but for those following this with other software it may be better as 666Azmodan666 suggests to create a three point circle using the original parameters whereupon the circle will intersect any new rectangle with the same top centre point.

[@wnebergall]

I like seeing the drawings but without Machining it it's just lacking something

[@cncnutz]

Thanks Bill. The only thing in this case is what would I do with a pirates chest lid?😀

[@wnebergall]

@@cncnutz well I could see a pirate chest to follow
