In this video, I’ll introduce the subject of Tiling Toolpaths, using Vectric Aspire Version 11.5. I’ll first discuss what toolpaths actually is, and describe the reasons for tiling toolpaths. Then I’ll show you some things that need to be taken into consideration before tiling, such as mounting the material. I’ll then show you how I intend to mount my project, and discuss the complications that introduced to my overall design.
I’ll show you the entire toolpath tiling process, step by step, and discuss important considerations along the way. I’ll then wrap things up by showing you the finished project, and save the G-code for each toolpath.
As usual, if you have any comments or questions about anything I covered in this video, please join me for the Live Q&A, or put ‘em in the comment section below.
On Sunday, June 25th, I’ll be hosting a LIVE Q&A session, where you can ask your questions pertaining to anything I’ve covered in this video. That Q&A starts at 3 pm Eastern time, Noon Pacific time. Hope to see you there!

Perfect timing I am getting ready to make a 6-foot sign on my Shapeokeo 3 XXL and I have never done tiling.
Good information mark im gonna have to try this.... Keep it up brother
Great information Mark. Thank you
❤❤❤
Good job ❤
Well presented Mark.
❤❤❤
Somewhat related: I needed to repeat a GCode in an array. a Mach3 wizard was able to do this for me
Mark, I've just been wondering when you are going to drop the 2nd video to this project?
I've been wondering that as well. As soon as a lot of behind-the-scenes madness calms down, I'll get back at it and finish this project. I have no idea when that's going to be, but this will be the first video I drop.
I know … I was like I can’t find part 2… so this video is misleading. I spent a long time looking for part 2…
@@MarkLindsayCNC Thanks for the update.
At least with VCarve Desktop there is a serious limitation with tiled toolpaths: there is no automatic ramp for a split toolpath.
As an example you can easily try this yourself. Create a profile toolpath with a ramp plunge for a rectangle, cut this toolpath to two different tiles and save the toolpaths into files. Look at the resulting gcode and you will see that the toolpath starts correctly with a ramp but all the recontinued parts (e.g. the entire 2nd file) of this toolpath use a straight plunge into the material. This can be a nasty surprise when using a downcut bit or a face cutter.
The reason probably is that Vectric uses some simple min/max calculations to split a toolpath into multiple tiles but it does not recalculate the new ramp positions when cutter has (rapid) moved to a splitted position.
Great presentation!
Because of expenses, I can only afford the Desktop version which only cuts 24"X24". My question to you is have you done or are you planning to do tiling of the same 6' sign on the smaller working surface (still in the 'Y' direction)?
Thank You for your help.
I'm getting ready to finally cut this project on my machine. I just had some projects jump ahead in line, and I had to get them finished first. Keep an eye out - hopefully I can get the video done and posted in the next couple of weeks.
Hi Mark!
Love the videos and they are very educational, so thank you very much for that!!!
So, if I have a 4' Y Axis on my CNC and want to make a 6' sign. Is there an easy way in vCarve Pro to setup a tiled project but instead of sliding the workpiece up or down on the CNC, but to take the workpiece out completely and flip it around 180 degrees and feed in the uncut side of the workpiece to the back. I realize that the CNC will need to know that the project is now upside down now.
I ask because where my CNC Bench is, I don't have any clearance to slide the piece back since it's against a wall on that end. I thought this should be easily accomplished, but I'm not seeing anyone attempting this.
I thought that I could just have two files and one is rotated 180 degrees, but wasn't sure if I was trying to reinvent the wheel. I suppose I can always create individual panels and join them together, but if it was possible, I'd rather keep it one solid piece.
Any insight or info would be very much appreciated.
Thanks again for all the videos!!!
Hi, I was also wondering if there was a possibility to do that, my machine is also against the wall. It must be able to do that but if it is in the software ? I just don't see it
Maybe to design the piece and cut it in the program in 2 pieces, flip one piece over calculate 2 toolpaths make an fixed mounting jig at the far y end of the spoil board just wide enough to get the board in an exact place mill the first half of the project turn the board 180, and then mill the second part (upside down)
However you cannot use a normal profile for the cutout you could of course cut the board exact to size on the table saw, that would solve 1 problem Yeah it might be doable at least for pieces no longer then twice the y distance of your machine. Hope my thinking gives you an idea at least kind regards Hans
Hi, I have been experimenting a wee bit, I cannot use my cnc at the moment, but I came up with the following
Just make your drawing in v-carve, somewhere in the middle draw a horizontal line from left to right. the you have to cut all the crossing vectors might use the convert to curves command so to split every crossing with the halfway line make you toolpaths for the top of the design , then select all, and paste it on a new sheet hit the number 9 key a few times to flip it 180 and make the toolpaths for the bottom part (which should be up by now)And like I said saw the board to the exact dimensions
Maybe try it out first on a piece of unused material just create a square of you dimensions and draw a simple diagonal line frm to to bottom draw a horizontal halfway line and cut the diagonal at that crossing create a v-bit toolpath fot both the upper and lower diagonal and try it out sucess again kind regards Hans
Would it not make sense to have 2 alignment pins to keep the piece straight and not use the pin as a pivot point? Good info Mark
Good question, Steve. I'll demonstrate further during the Live Q&A, but basically, I'll have 2 other pins running along the left side of the project to keep it from pivoting.
