EP3 Onefinity CNC - 3 Must Haves in a CNC Wasteboard: Includes MATCHFIT Dovetail Wasteboard System Files FREE. Includes files for Vectric and Carveco. Sizes support Foreman, Journeyman, and Woodworker!

How strong is your wasteboard game? In this video, Morgan shows off the wasteboard that he designed for his Journeyman, and explains 3 critical characteristics that make a great CNC wasteboard.

  1. Flatness - To get the best results, your wasteboard should be perfectly parallel to the machine’s Z-axis. Kind of a no-brainer, but often overlooked.

  2. Workholding capability - Morgan’s wasteboard is built around Microjig’s MATCHFIT system - incorporating a grid of dovetail tracks to secure a variety of fences, stops, clamps, and hold-downs to secure material.

  3. Consistent material positioning - With a built-in positioning system, you can save a TON of time setting the origin point of your toolpaths. With a fixed, known origin relative to your machine’s home position, toolpathing is a breeze.

                             ***JUST ADDED***

Cleanup toolpath! Included with the updated file is a cleanup toolpath. What the heck is that? It looks a lot like a surfacing toolpath, but it doesn’t cut anything. You fire up the vacuum, drop your dust boot, run the toolpath, and the machine runs across the entirety of the wasteboard, sucking up all dust and debris…

If it’s time to replace your wasteboard, you might want to take a closer look at this dovetail system - it’s pretty neat.

Vcarve (v.11) SVG and DXF files for the wasteboard and detailed instructions are available for free right here…

If you have an awesome idea for a wasteboard or workholding system, we’d love to see it!


Thanks for sharing these, Morgan. I was definitely interested in this setup since I picked up some Matchfit Dovetail hardware a while ago and still haven’t put it to good use.


What material and size is the actual wasteboard? I’ve had the Journeyman for five months now and still the wasteboard set up gives me the most issues. I might try this method

Same! I built a tracksaw MFT-style table a while back and got a little ambitious with my matchfit order. This will be great!

The actual wasteboard is 32x48, but I made the toolpath only 31x47. That prevents me from cutting too close to any one edge and I think keeping even a small solid border around the cut area will help keep it flat.


Oh, you can do SOOOO much cool stuff with the hardware!

@MorganHop Would you re-flatten at some point or make a new one? I am thinking flattening an existing one would reduce the effectiveness of the dovetail tracks. Also, do you run a pass with the MatchFit relief bit or go straight to the dovetail bit?

I’m curious about the QCW setup. Have you just got that full size wasteboard mounted on top of the provided QCW Track?

Yes, that is how it would work.


Absolutely! Relief grooves have a dedicated toolpath, run right before cutting the dovetail tracks. Microjig’s 1/4" relief bit isn’t necessary though. Any 1/4" bit will do because the dovetail bit is just gonna plow through it all anyway.

It’ll probably be a VERY long time till I need to replace it or even flatten. I check the thickness of my material with a caliper before even creating the toolpath. and I set the cutting depth to just .005-.010 shy of the full thickness. I understand the wasteboard is there to get cut into, but I prefer to avoid it whenever I can


So plywood or MDF? All the pics seem to show plywood. Will MDF hold the dovetail hardware without breaking down?

Thanks. I think I’ll try this. I built a tee-nut wasteboard or should I say mis-made as I found my machine is juuust slightly out of square enough to notice in the cuts. I love the matchfit jigs and sleds I’ve built.

Yeah it’s just on top of the QCW. The dovetail tracks are 3/8" deep so putting panels in between the tracks wouldn’t work. I used the tracks to attache the wasteboard to the QCW with 1/4-20 screws and nuts

I dove into that in this video I did a few years ago at Microjig. This link should start the video in the right spot for you, but the information you’re looking for starts around 1:47…


This is crazy awesome Morgan!

Thanks for sharing it with the Forum… very cool.

Question: For those of us that are not VCarve users, you don’t happen to have anything that can be used in Fusion360 by any chance do you?

If not no worries, just though I’d ask, not sure if VCarve can export outside its file system or not.

Cheers and thanks again!

I had someone message me on Etsy asking the same thing. I’m going to take some screenshots of all the information he needs to toolpath it in Fusion360 - bit information, passes, depth, tabs, etc…

He said he’ll send me the Fusion360 files once he’s done and I’ll include that in the next version of the file, and send them to anyone who has messaged be about it


That would be awesome Thank you Morgan!


You can select the vectors and export them as a DXF too.

This is awesome, @MorganHop! Great video too! I really like the clamping pieces you’ve designed as well. You did some really good work putting this all together.

I set my wasteboard up with the Matchfit Dovetail system about a year ago when I got my Onefinity and have loved it. I have a few precautionary notes about it that I think are worth mentioning:

1 - The bolts that come with the dovetail kit are really short. They have some that are just the nut in the dovetail that you can put allthread and a wing nut on though, which work much better. I’ve thought about making some out of wood or HDPE and some treaded nut inserts, but haven’t gotten around to it yet.

2 - The plastic dovetails are not very strong. I’ve broken about 4 of them because I tightened them too much trying to secure my workpiece (unsuccessfully of course haha).

3 - The dovetails tend to stick to the wood after tightening them. You have to push them down pretty hard after taking your material off in order to move them around sometimes.

4 - The nuts that come with the kit are huge and get in the way of the dust boot if you’re not careful. I’d recommend replacing them with smaller wing nuts if you run into the same problem.

5 - Make sure your dovetail piece is 100% inside the track. There were two times that I had them partly in the track and partly in the entry pocket, and they busted out, taking a chunk of my wasteboard with it.

Over all it’s a great system and I really like it though!
