Reducing 3D Machining Times - Part 27 - Vectric For Absolute Beginners

[@محمدحسن-خ2خ2ف]

رائع جدا ...شكرا على هذا العمل الكبير و هذه المجموعة مزودة بالترجمة الهادئة ...

[@darrylpococke6401]

As always I walk away from these videos a lot more prepared for these projects!! Thank you again.

[@BlacklandGrass]

After running my first 50 or so pieces(1st twoprojects) , this was a reveal on a much deeper level! Thanks!

[@josiesuter6517]

This is the video I've been looking for for months!

[@gdanielhoracio58]

Wow thanks Mark, I did on a project just like in your video and I reduced the time in 4 hours, at least in vectric, now I have to try it on my cnc router, thanks again.

[@richardpoulin2947]

Thanks Mark you really know what you're talking about, very well explained!!

[@farmlender01]

Huge time savings. Thank you Mark

[@powerpc6037]

Could you speed it up even further by selecting all 3D models and give them all a boundary vector? So instead of having to do a 3D roughing pass and a 3D finishing pass between rings and banner inside the whole area around it where you created almost a square boundary after adding the lines between the outlines of both banners, you could let your pocketing tool do the clearing between the rings and banners. They take away more material at once so it should be finished even faster.

[@MarkLindsayCNC]

Yes, you could do that. In fact, that's the preferred method. I didn't do that in this video so I could give a better demonstration of how much of a time reduction you can get by adjusting the plunge rate. I did demonstrate using a vector boundary and pocketing out flat areas in all of my other 3D carving videos - except for maybe one or two where I was demonstrating something else.

[@luckettg]

Another excellent video that is helping me with this problem. It also taught me some better methods of project layout too. Thank you, Mark!

[@MarkLindsayCNC]

Thank you very much! Glad to hear it helped!

[@bosshogg8621]

Can you please explain why you used a negative vector offset on the 3D roughing toolpath? Is that a time saving or a quality strategy?

[@andregignac2443]

now I know how to use Project to 3d! Thanks Mark!

[@MarkLindsayCNC]

Thank you, Andre! I went over it in much more detail in this video: kzbin.info/www/bejne/iqqoeZuhnqqhebs

[@wallystoolshed7050]

Once again Mark, thank you for the very informative video. Lots of good information, Hope I can remember it all

[@MarkLindsayCNC]

Thank you, Wally! The video coming out this Sunday will REALLY help you reduce those 3D carving times, if you're using Vectric Aspire.

[@HarnealMedia]

LOL Love the sentiment. Almost better than the original one

[@MarkLindsayCNC]

Thanks, Steve - lol

[@Speido307]

Great video, I have been watching and learning, I did wonder if you had a suggestion on getting free 3D images (stl) files.

[@DaveGatton]

Great tips Mark! Time is money baby!!!! :-) Send my love to Fred and Hazel.

[@MarkLindsayCNC]

Thank you, Dave! Fred and Hazel say thank you as well!

[@hollandworsham1372]

Great video. I'm curious why you chose to raster the finish toolpath. I usually raster (with the grain) the roughing toolpath and offset the finish. It seems faster to offset the finish, but I could be wrong.

[@MarkLindsayCNC]

I find I get a better finish with a raster toolpath - especially on a softer wood like Mahogany.

[@indeeray]

Mark, my name is Ray Walton and I really enjoy watching your videos, they are very informative for the beginner. What I am wondering was, would you sell me the Aspire file for the wedding sign? My son and his bride are having their first wedding anniversary coming up and I think this would be a perfect gift. I have version 9.5 in Aspire. Thank you in advance for your reply! Ray

[@bobheltibridle6023]

Thank you Mark, I'm still picking up the finer things

[@MarkLindsayCNC]

Thank you, Bob!

[@dptp9lf]

Excellant Video Mark... Thanks very much!

[@MarkLindsayCNC]

Thanks for checking it out, Lyle!

[@selwynadelson]

Another great video but just one question. If you increase the speed rate on the fly does it adjust your plunge rate as well as the feed rate or only the fee rate?

[@MarkLindsayCNC]

Thank you, Selwyn! I use Mach3 controller software, and yes, when I increase feed rate on the fly, it also increases the plunge rate. I have Mach3 set up to increase the feed and plunge rates by 10% at the push of the button, and I can increase up to 300% total.

[@selwynadelson]

@@MarkLindsayCNC Thank you Mark. I use Carbide Motion to run my Shapeoko machine and I am not sure if it does likewise or just increases the feed rate. I will check this with the Shapeoko people.

[@kennethbroussard2587]

Thanks for all the great info, it has helped me understand the process better. But I have a question. I tried to follow all the steps here, but when I preview and actually carve, I get a small amount of uncarved material along the the outer offset boundary of the model. Just a thin line of material that would have to be sanded away. I tried with the -0.125 offset in the roughing path and without, but still get that leftover material. Any ideas what I might have missed in the process?

[@kennethbroussard2587]

I think I figured it out. I put a 3rd offset between the model and the first 2 offsets, and the toolpath previews are showing that line of material being cleared now, after adjusting which ones were chosen for each toolpath. Cutting it on my CNC now to see how it comes out. Thanks again for the great videos. I learned quite a bit from this one.

[@jimsinacola-totallywoodwor7473]

Afternoon Mark and all!

[@therambler3833]

Very informative thank you for sharing . I wish the videos on the channel more organized so I can start at the beginning i'm a little confused can you please link me to the first of this series. Regards

[@MarkLindsayCNC]

If you look at my channel's main page (click my name) you'll see PLAYLISTS right under the banner picture. Click that link, and you'll find all of the playlists I've created for my channel. Here's a link to the playlist all of the videos in the Vectric For Absolute Beginners series: kzbin.info/aero/PLLuYLaC3-QRNuVTej2P5emp1D4_Tm774p By the way - the videos are arranged in the order they're posted in, newest to oldest.

[@Kapaljaring]

Thx

[@davidwhite2011]

Do you make the aspire file available? Is there a video on improving milling times more traditional objects? Is there that much different between three d object and the standard primitive objects.

[@MarkLindsayCNC]

Thank you, David. The file is a composite model, made from the Clipart that comes with Aspire. Here's a link to a video I did on the subject: kzbin.info/www/bejne/aWrHn5eimpmAosk To reduce machining times on 2D projects, it's basically a case of adjusting your feed rate to get the optimum performance. There is no magic answer on that, because every machine and machine setup is different. You'll need to experiment to find what works best for you.

[@davidwhite2011]

I have Aspire, was just going to follow along if you made the file available.

[@MarkLindsayCNC]

I really didn't think making a file available was necessary, since all of the individual models are already available in Aspire. Plus, assembling it yourself lets you chose different banners if you find something else you prefer (for example, something wider, to allow for taller text.) It really is a case of dragging a model onto the material surface, then arranging it into the position you want it in.

[@georgechambers3197]

One question, when you did the 3D roughing it was set to leave 30 thou. You started the 3D finish at 125 thou deep but was 270 thou deep when finished? What happened there? Otherwise straight forward and well presented. Sorry, I had to miss the live video today, but thanks for this video!

[@MarkLindsayCNC]

The way that machine allowance works is the roughing toolpath leaves, in this case, 30 thou for the finishing pass to clean up. It has nothing to do with the depth of the model. The total depth of the finished model was .27.

[@georgechambers3197]

OK, still doesn't compute. If you ruff cut down to .125 and have left .030 for finishing but the finish cut ends at .270. That seems a lot more than .030 left for the finish cut after the ruff cut?

[@MarkLindsayCNC]

That's because I used the Z level roughing strategy, rather than the raster strategy. I'll talk about it in next week's Live Q&A - it's easier than to try to type it out in text.

[@georgechambers3197]

I'll be sure to try and make for that. Thanks Mark for trying to get it through my thick skull. 😁

[@shelby50411]

Couldnt you just create a rectangle around that 3d area its way simpler and faster...or am i wrong?...lots of great tips though...love it.

[@MarkLindsayCNC]

Thank you for checking it out! Yes, you could just create a rectangle around the 3D area if you want to, but it'll take longer to machine. The whole purpose of creating that vector I put around the model was to reduce the amount of material that the 3D roughing and finishing toolpaths will carve away. It's much more efficient to pocket the flat areas than it is to 3D carve them.

[@shelby50411]

@@MarkLindsayCNC you are correct....but im not very proficient at vectric aspire so creating a rectangle is easier and still reduced machine time a lot ..your method is better for sure but still uses the same theory as the rectangle and that is reducing machining time..3d machining takes a long ass time and i dont do it often due to that..my cnc is not reliable enough to run hours at a time unattended lol...for me the longer the machine time the more chance of having a boo boo ...

[@swamihuman9395]

Good stuff, Mark. Sub'd:)

[@MarkLindsayCNC]

Thank you very much, and welcome aboard!

[@andysnead4499]

How do you see your machine times?

Hazel should be on the left (Ladies first).
