Cutting beyond the front rail

Post by Jeff » Mon May 07, 2018 12:25 pm

I want to do some box or finger joints on my XXl.
I know that the Dewalt will extend past the front Rail .
From the rail to the center of the router bit is 1 7/8" inches
I can make a holder for the wood which will not be any thicker than 1/2" thick.
I have a design for making the pockets and pins line up.
Just not sure how of if i can get the unit to move to a start position on the wood.
Any ideas on how to do this,or where there might be a video

You'll need to jogthe machine out and set zero normally, or design the jig so that it is in front of the machine.

The way I'd do this would be to set the zero at one of the front rapid positions on your machine, measure how far it is from there to the front rail, then design it using a centered origin in your CAM app and use that offset to put things relative to the rail from that position as center/origin.

Yes, I believe so. (Your image is a bit large, so had to scroll around it).

Will,

For viewing large images on this forum, I have found it easier to right clicking on the image and then choosing the "open image in new tab" option. When done this way, the image is shrunk to fit the page automatically, with the option to click on it to zoom in to the actual size.

So if I create a file design and on one edge of it I create the 1/2" cutouts that I need to make the box joints.
Use the front center rapid position as the start point and add the distance to the front rail and make that where the inside of the box joint start. Then add some distance to that so the cutter will go all the past the otherside of the wood 1/2"thick woo I am using.
Use a piece of wood thick enough to set the z position high enough that it won't hit the front rail. and mount the wood upright in front of the rail and run the file .
Does that sound like how to do it

Found this on you tube.
It is a file to do what I want to be able to do cut finger joints

Yes, just work up a fixture to hold the pieces on end.

Will I be able to jog the router beyond the rail and set x and y and the z.
Before I run the cut file.

Yes. The machine layout isn't programmed into the machine beyond the rapid positioning positions and table size.
