CNC 3018 Spoilboard Construction

- Опубликовано: 26 авг 2024
- My first project for my new CNC3018 mill was to create a spoilboard for it with threaded support holes.
The design was made in Fusion 360. I used a 1/8 flat mill for the holes, 1" clearing bit for surfacing, and a 1.5mm flat mill for the lines.

I know this is 3 years old but can you share the G Code for levelling the 300X180 Mdf board please. Love the video!
Looks good. How did you attach the board to the aluminium base?
I used T-slot nuts, similar to those used to attach the base to the bearings. I think it was M6 hex bolts down through the 6 top holes into these T-slot nuts @1:50 in the video.
@@MeracoUK @MeracoUK thanks for that. Looks obvious now. Need a bit more practice in fusion to design something similar.
I would love to have that. can you share the project, please?
What is the actual size of the spoilboard? The bed is 300 x 180, but it can only carve 278 x 157. I want to make a full size spoilboard, but can't figure out how to start the carve from the center. Also, it looks like your machine doesn't have limit switches? So maybe you can carve the full 300 x 180?
The board is 300x180x18. I don't have limit switches yet and the spindle covers the full 300x180 limits of the bed. Any holes you create have to be within the limits of the machine travel, but the width of the surface bit allows preparation of a slightly larger surface than the spindle covers. My Fusion360 project assumed 300x180 material with machine origin at bottom left corner. In my case, if I did it again, I would oversize the spoilboard about 1cm compared to machine limits, and carve a rectangle following spindle limits showing useable area.
Can I ask what was the levelling tool used? Did it fit in the stock standard collet?
I used a Whiteside 6210 surfacing bit. This has a 1/4" shank. I had bought a set of ER11 collets which included a 1/4" collet.
what was your surface speed for the facing?
Its a long time since I did it, by my files seem to indicate I used 833mm/min plunging and 2500mm/min for cutting, with 10mm step over and 0.5mm depth for roughing cuts. However I would use one fo the CNC spreadsheets available on the web to recompute if I was doing it again - this was very much a learning experience.
what material did you use for the base?
I used 18mm MDF. I made sure to carve it near the dor with a good flow of air to the outside.
please share a link for the flat mill
Its a Whiteside 6210. I bought it from Amazon.

Your lines are not square. why? is this because the CNC is cheap or..?
Are you referring to the surface grid lines being slight askew to the grid of holes? If so, that is because the board is moved between making the holes and scribing the lines. First the holes were drilled. Then the board removed (unstuck) from the mill, then screwed back onto the base, before the board was surfaced. I did not take pains to re-align the hole grid with the frame when re-attaching as the hole alignment doesn't matter, their just to hold stuff down. The grid lines, however, should be square with the frame.
opps, there went half of your Z axis.
Yup. Its limiting my spindle upgrade too. Thinking of milling some taller gantry uprights out of some phenolic board.
I would love to have that. can you share the project, please?
