Has anyone cut T-Slots in their wasteboard?

I'm with Damin69, I use t-track only and use a 1/4" sacrificial waste board so I don't cut into my top surface for through cuts. I just bought 24feet of the orange T-track for a second bigger CNC. It was cheap compared to buying from rockler or woodcraft.

Yes. Very True. Plan to put metal about 1/4 inch below surface no matter what I do.
Normally I hate plastic replacing metal parts on most everything, but this is one time I wouldn't mind if there were plastic parts hard and strong enough to use for some hold down methods.

One thing I’ve been considering is 3D printing puzzle pieces to use as a Wasteboard. I figure if I made them symmetrical I could flip them for a second use, then compost the PLA.

48" T track for less than $8 each..

How far apart did you space the tracks?
It lists the tracks at about 1/2 inch height. How far down below surface did you position them?
From the picture it looks like you would just cut a slot to the width of the track you are using and set the track into the slot. How is the track fastened to the MDF?
With glue? or does the slot have holes to anchor it into the MDF?

Thanks

I do not remember the exact spacing. I had a piece of 3/4" MDF that was 30" wide I believe I cut it in 6" strips. As far as below they are just fastened down flat to my piece of 3/4" Baltic Birch board I have placed on my frame. Everything is just spaced equally across. I screwed the Ttrack down and I Glued the MDF down. Then I ran a surfacing bit over the top of the MDF to level it off.

Since I have a table saw, I used a dado set to cut the slots. I used 4 tracks and just evenly spaced them out. The track itself has screws holes already drilled a few inches apart. I used small nuts and bolts instead of screws for more holding strength. There is not much mdf left after making the slots. Don't use glue since you may want to easily take off the tracks and make a new spoil board.

I used rocker t-track for this CNC before I found out about orange aluminum.

Thanks for the info on the tracks. Right now I I have a piece of 3/4 inch mdf and already ordered some Tnuts so I will try that method first.
I will get a 1 inch board (or glue two 1/2 inch boards together) so I have more "meat" to try the track idea when I get the time. I like the track idea.
I will mention that to my son who has my old Shapeoko 2. Now he is going through the same "growing pains" and asking about different types of wasteboards and hold-down methods.

I am assuming your "upper wasteboard (the one with tracks) is screwed into the lower wasteboard. Is that correct?

Thanks

YEs that is pretty much what I have done. I would not really call my bottom piece a Waste board as it is more part of my base as way to attach the waste Board to the base.
My set up is from bottom up.
1) 20x40 extrustions
2) 3/4" Baltic Birch Ply Base
3) Ttrack and 3/4" MDF (hold down/Wasteboard area)
