How do you square your rotary tool?

Postby Dustin Hawkinson » Mon Jan 09, 2017 3:54 pm

To kick things off in the new rotary tools forum, I thought I would ask if anyone has any good ideas on how to square your rotary attachment when you place it in the bed. I've tried all sorts of different temporary methods, but I haven't come up with anything I like yet.

I have been thinking about this too. What I think would be best is a vertical jig that you place on the ends of the rotary that "reaches up" to square you against the X axis gantry. Something that attaches/fits over both ends of the rotary attachment and reaches up to touch side of the X axis gantry. Just as important, ideally it would also be spaced to position your rotary just the right distance from the gantry so that the nozzle is exactly positioned along the center line of the chuck (or center line of the two most used rollers for the hotdog roller type). This would be much more versatile than doing something down on the bed.

How about a third type? Wheel type similar to an epilog.

And I sight down over the x rail down to the back rod of the rotary. Easy.

I use a 6" steel ruler and reference from the edge of my bed - no need to be overly elaborate but accuracy counts.

As long as your bed is square in its construction and your bed's front edge is truly parallel to the X gantry, that would work. Unfortunately, with Chinese lasers the user may find one or both may not be accurate.

This does not need to be complicated or rocket science.
Take a few minutes to square up the rotary with the rails and gantry.
Make a jig that fits into your machine at whatever position you are normally going to use the rotary.
I use a simple piece of 1x4 that was cut to fit square between the rotary and the jack screw nuts on the bed.
Keep it with the rotary.
This works well for other repeat projects also.
Just keep each jig with each mold or in this case with the rotary.

I really like that Willy. You can make the jig fix any square problems you have (for example, I can not square off my bed), and then just throw it in each time. I was going to mount a reference rail to my bed but I like this more.
