This is the 44th in a series of videos geared toward the person who has never worked with CAD or CAM in the Vectric Software before.
I’d like to thank Ahmad Eivaz for allowing me to use his photos in this video. Thank you, Ahmad!
In this video, I’ll introduce you to Ramps and Leads in Cut2D Desktop, Cut2D Pro, VCarve Desktop, VCarve Pro, and Aspire.
I’ll show you what Ramps and Leads are, then give you a couple of examples of when you would want to use them. We’ll get into some Profile toolpaths, and get into the various settings we have available to us for adding a Ramp, a Lead, or a combination of the two. I’ll then demonstrate the toolpaths and Preview a couple of them to show you a few things to watch out for when adding Leads to a toolpath. Finally, I’ll show you a common error message that you might run into, how to fix that error, then recalculate the toolpath. Please keep in mind that this is an Intro to Ramps and Leads. There are many other options and settings to be explored, but this will give you an overall view of what Ramps and Leads can do for you.
As usual, if you have any comments or questions about anything I covered in this video, please put ‘em in the comment section below.
On Sunday, May 24th, I’ll be hosting a LIVE Q&A session, where you can ask your questions pertaining to anything I covered in this video. That Q&A starts at 3 pm Eastern time, Noon Pacific time. Hope to see you there!
Here’s a link to the Live Q&A: • LIVE Q&A #40 - Ramps a...

Amazing content, greetings from the Dominican Republic. Thanks a lot!!
Great video man. Playing the video at 2x speed is perfect.
I didn't know they were called dwell marks and I thought I was the only one that had to deal with them - - sand, sand, sand. Everything I've ever cut gets them. I need to apologize to my machine. I get something valuable out of every single video you produce, but this one just changed my CNC life and saved me a lot of sand paper and frustration. Thank you.
Thank you Alan. As I said in the description, there are a lot more settings and options to explore, but this was a basic intro. Ramping, along with a Separate Last Pass will totally eliminate those dwell marks. Here's a link to a video I did on the Separate Last Pass: th-cam.com/video/kFIkyl8tUFU/w-d-xo.html
Your videos/tutorials are fantastic. Thank you.
Really appreciate you taking the time to make this video.
Never really understood these concepts before, but I have had problems that COULD have been solved by using these. You are a GREAT teacher, and a very practical machinist. You show us exactly HOW to use these tools, and as a GREAT bonus, WHY we'd use these tools.
I'll be sad when I get to the end of this great series, but then there's a LOT of other videos here as well! lol
Thank you Man.
A really great and informative video, Mark. This is the first video I have seen of yours, and I found it very helpful in understanding Ramps and Leads and when to use them. I knew very little about these before watching your video. Thank you!
complimenti sei veramente bravo grazie mi stai aiutando moltissimo ti sono riconoscente un salutone
Very well done, Mark. Be safe.
Very good demonstration again Mark 👍. You always give me tools to make my projects even better
Excellent tuition, many thanks Mark
Another great educational video! Thank you.
Great video. Great teaching. Every Aspire user should subscribe to your channel. Muchas gracias!
Good info Mark. I have often wondered about ramping in
Thanks Mark !!! this helped a lot !!!
Great video! You just saved me three hours of time
Glad I could help!
Thank you. I’m learning a lot from your videos.
WOW Thank you
Good timing. I was doing my clock gear tool paths yesterday and had one where it did not detect that a lead would gouge the part. I just went through and adjusted the lead lengths on the gears. I am using them to reduce the pressure on the parts when cutting. The gears are for Brian Law clock 22 and are being cut out of 9mm thick black walnut so pretty fragile stuff compared to plywood. The smallest is 23mm diameter with 7 teeth.
Perfect timing Mark. This is exactly what I needed. Great video!!!
Great job as usual. I'm like you. I nearly always use the smooth ramp. I have found the Spiral ramp to be very helpful when pocketing out holes instead of drilling. I use a slightly smaller bit than the hole diameter and spiral ramp to my final depth. This has proven to be much faster than drill pecking and less wear on the bit when applicable. Since most endmills aren't designed to plunge/drill, this works well.
Another very informative video Mark. Thank you for taking the time to share your knowledge with us. Have a Great & Safe holiday weekend. Let us Not forget, what this holiday is about
Great information. Thank you.
great explanation. thanks.
Well Done!
Another brilliant video, thank you Mark. I’m thinking, on a smooth ramp I can get close to my feed rate with the plunge. 1/8th” bit doing a profile, might as well smooth ramp in at federate if it’s going to take off at depth anyway.
The ramping speed is controlled by your Plunge Rate in the tool database. I would advise caution in setting that Plunge Rate to the same as your Feed Rate, as ramping in focuses a lot of stress on the tip of the bit until it gets to the final depth of that ramp. Ramp in too fast, you can shear off the tip of the bit. I've done it too many times due to being impatient. I'm not saying not to do it - just be cautious, and watch it closely when you do it. You'll soon find the limit of the tool (usually by breaking it.)
Awesome tutorial Mark, you covered all the bases, thanks 👍
Thank you, Brian! I didn't quite cover them all. This was just the intro video, to show you how Ramps and Leads work. Next week I'm going to show you some different settings to make them work better together, and incorporate the Separate Last Pass option to further clean up edges of profile cuts.
Mark Lindsay CNC ,Looking forward to it Mark, I use ramps regularly, but I have never used leads, and your video honestly helped me understand them.
Thank very much Mark. It is what I need since long time. But can you Leads in/out an Open Vector? Because I can't
Excellent!! Thank you. How does using a spiral ramp affect the feed rate of the final pass? Can the feed rate of the final pass be changed?
I don't know if you've already done a video series on this but could you put out a series basically from very beginning of v carve all the way through G-Code actually cutting the product step by step for us really really super beginners thank you very much
I never knew the term dwell mark before. I get these marks when I utilize the tab option and I never knew the term or what caused them. I actually thought it was a tramming error.
If you use 3D Tabs by checking the box, you'll reduce the likelihood of dwell marks in or near your tabs.
Very informative and helpful video, Mark, thanks a lot.
I have a curiosity:
an up cut bit tends to pull up the stock material from the spoil board and a down cut bit tends to push down the stock material or is it the opposite ??
I'm not able to figure it out :-)
Thank you very much! You're absolutely right. An upcut bit slices the material fibers with an upward motion, which can lift a piece upward, and a downcut bit slices in a downward motion, which can push the material downward.
Hi Mark! Thank you for making such amazing educational videos. I´m slowly going through all of them and I´ve learnt so much! I have a problem that I hope you will take the time to answer for me. When I add tabs to my project I end up getting these marks that you showed in the video. I get them before and after the tabs. Any idea of how I can get the problem fixed? Thank you so much for your help so far :)
Thank you very much for your kind words. There are a couple of things you can do, and I detail them in the next video in the series: Part 45 - Combining Ramps, Leads, and a Separate Last Pass. Here's a Link: th-cam.com/video/lI4ZM2xMabs/w-d-xo.html
@@MarkLindsayCNC Thank you! I will check the next video out :) Keep up the amazing work!
Great videos!
I want to reduce the outside dimensions of rectangular aluminum plates that are 6.5mm thick. Is it better to let the end mill (1/4") do simple plunges and cuts as per normal for the profile toolpath or is it better and easier on the bit to set up leads that are outside the material dimension and only allow it to come in on the side of the mill bit? Intuitively, this seems better to me as I can probably get away with larger cut depths since the top of the mill bit is never used.
You're on the right track, and your instincts are correct. Your situation is exactly what Leads were created for. Sometimes it's better to ease into the material from the side, rather than plunge in from the top. You'll experience less bit deflection where it matters if you use a lead.
Thanks Mark, I was about to post a question in the Vectric forum and thought about checking this out on your channel and you had it, great explanation, you saved me a lot of time.
Question I found trying this...how do you do the lead in on X and the out on Y, forming a cross? That looks to me like the most efficient way in cutting a square. I do not find a way to make this, the lead out just goes over the lead in....thanks.
I think I answered this in Part 2 of this 2-part series. If I didn't, please let me know so I can try to help out. th-cam.com/video/lI4ZM2xMabs/w-d-xo.html
Little need of help here.
I have this mdf plate:
- top - 499x499mm
- base - 510x510mm
- thickness - 59mm
I want to make a profile toolpath that cuts in angle of 84 deg. Since the base is larger than the top then all sides would have an inclination. What setting should I use in order to have that inclination to the sides as a result, cause what I'm setting so far it only cuts straight sides and I don't want that and I'm lost in translation here.
Thanks.
Thanks a lot for your videos. A question when you say the bit contact with the material is the plunge,after making the toolpath it retracts again to make the second pass. But how can I that it doesnt make the retract?I think when it cuts the first pass, the bit is now in contact with the material, so why could the bit make the second pass without the retract?
thanks a lot
There might be a misunderstanding. The tool will make the first pass, then plunge down to make the second pass, then the third, etc... It will only retract from the cut when the toolpath is finished running, if you use a Separate Last Pass, or if you use a Lead In without a Smooth Ramp.
@@MarkLindsayCNC thanks a lot. Until now every piece I make, makes one path,stops,retract snd start the second pass. But after wour video I undestrand that using ramps, I will save this times of retracting . No?
thx so much, i really apreciat this lesson, ihave an question, on aspire, when u choose v carving only can hable Ramps if use a area clear tool and cant change the ramp mode you need, can you explain ? thx so much i realy learned very much with u lessons
The v-carve toolpath only carves what's inside the vectors. It knows that the v-bit has a cutter edge all the way down to the tip, so it doesn't need to ramp in - that's why you can only use the Ramp Plunge Moves for the clearance bit. The software doesn't know what kind of clearance bit you're using, so it gives you the option to Ramp Plunge Moves if you need it. The ability to change modes is unnecessary, as the software takes the Pass Depth from your Tool Database and figures out how to ramp in based on the amount of space it has to work with.
@@MarkLindsayCNC Thx so much, i watching all you vids, at beggin first, thx so much, i really apreciat you moustach, i have an small moustache also, thx sir !
Hi,
iam a beginner in vcarve desktop 11.5
My ramp always starts at Z0 🙈 and i don‘t know why.
Greetings from Germany
Do you have a video explaining "Do a separate last pass"? Thanks
Thank you for checking out the video, Lane. Yes I do have a video on the Separate Last Pass. Here's a link: th-cam.com/video/kFIkyl8tUFU/w-d-xo.html
why is the result of my work when using a ramp, the result is always the beginning of the cut when it starts to plunge slowly it is more out of the vector path. While when it is finished it is vector. I don't use leads. I use in vector profile toolpath
