CNC Router Vacuum Table - Part 1

- I am modifying the CAMaster 4x8 router table into a vacuum table.
The steps in this process are to surface the table top, cut holes for the plumbing connections to the vacuum system, and then cutting the grids for the different zones on the table.
Since the table top material is MDF, once I surface it and cut into it, removing the skin layer, if I were to apply vacuum to it in its raw state, the vacuum would not only pull from the channels that were cut into the material, but actually pull sideways as well. To further explain, in my experience MDF is a very porous material and will allow air to pass through it like a sponge. This is not limited to just a "vertical direction" but it will pull from all over. So if you are using a single zone, you will not have the full force of your vacuum pulling down because it will lose vacuum by pulling from the other zones adjacent to it. So you can lose a large amount of your vacuum from other zones in the material because they are not technically sealed. To help with this, I chose to seal it by painting it with a latex paint. This, while not 100% effective will greatly increase the pull from each zone. Essentially this blocks the loss of vacuum and will give you greater holding force.
This is the first of three videos of getting the CNC ready to start making chips.

You're correct with your y-axis orientation for the raster...faster with the longer runs because there's less impact for acceleration/deceleration than there would be with x-axis orientation.
Thanks Jim. I will look forward to your comments in the future. I am always open to new ideas and learning from others.
Have a great day!
Nice machine you got their Paul
Thanks Kevin.
Great info, this gives me some great ideas. By the way the second tool path wouldn't be needed if you used a pocket allowance of just a little more than half the diameter of your surfacing bit.
You get a great edge finish, do you mind sharing the bits you use? Also, how powerful is your spindle motor?
Great Job so far. Will be fun following along with your channel.
Thanks, I'm looking forward to making more videos. Thanks for watching.
That machine looks amazing. I look forward to seeing you put it through its paces.
The addition of the lathe is really intriguing.
Hopefully you don’t get too many @$#€₽££¿ that say CNC isn’t woodworking. There always seemed to be a lot of them on the FB Woodworking groups.
Well, that is true... some people do get offended when you use a machine to do woodworking... There's not really any other term to use to describe it.... Fake Woodworking....?? LOL
Its all good.
Thanks for watching and taking the time to comment.
Magnifique
Just used a negatively offsets when you program the pocket.
Looks like you did a great job. What is the thickness of your vacuum table? How wide and deep did you make the channels?
Thanks for the comment. The table top board is 3/4" thick. I used a 3/8" bit, so the channels are that width, and I should have gone 1/4" deep, but I had my depth set to 3/8" and I didn't catch it in time so I just let it run. And since I am putting a spoil board on top, it shouldn't matter much. Thanks for watching.
Love your intro/title animation!
How?
Here did you get the pumps, thanks
Hello - would love your review - I am in the market, I really like the Stinger 3 as you bought, but the gantry supports look small compared to others. Are you concerned with step motors? From what you are doing it is clear you know a lot about CNC, I am a novice, looking to buy my first machine - thanks in advance
Actually, this is my second CAMaster... this one is almost identical to my first one. This one I bought with the lathe attachment. I only got rid of my first one because of downsizing my shop, so I kept the newer one.
I ran my first machine hard... and hardly had any issues with it, besides the normal maintenance of wear and tear.
Great machine. I would buy another before any other brand.
I would recommend buying replacement gears for the rack and pinion... they were really the only part that wore down after a year of heavy use.
Gantry is a lot stronger then you may think.
Stepper motors are perfectly sized for the machine.
@@x3cnc479 thank you for the reply :)
@@x3cnc479 what spindle did you pick. thanks
where can i get the project?
Great job! I have the exact same machine, with X3 and rotary index currently using black box Hurricane and want to completely rebuild the table. Will you please share your cut files, I have Aspire 9.5
I can, but it will take me a few days. Check back in a few days. Thanks for watching.
@@x3cnc479 no hurry, thanks

Can you share the vectric file that you created? I found the file in a previous post. Thank you!
