My plan for quick change was to have a separate piece of z axis makerslide for each type of "spindle" and then remove the two bolts attaching the z axis motor to the z axis makerslide to change between spindles. (see pix below bolts circled in red).
Steps to do this would be
1) remove bolts
2) un-thread z axis threaded rod from z axis nut
3) remove old spindle from machine (mounted on makerslide)
4) drop in new spindle into machine (mounted on makerslide)
5) thread z axis into z axis nut
6) reattach attach bolts to new spindle
This shouldn't take more then a few minutes and shouldn't need to do anything but re-home the machine. My thought is once I get my router (or other "spindle") mounted square and plumb to the makerlslide I don't want to have to remove it to mount something else!

"Erector set" mentality - simplify pieces to make better use of the aluminum extrusion's versatility & allow for other robot designs from the same parts.
Offer kit without Makerslide or in different sizes - the standard 8x8x3" cutting area is fairly limiting considering how cheap it is to buy longer Makerslide.

What else is on the wish list?

I will have to draw something up so that you can see what I mean, but the basic idea would be a solid mount plate that is fastened to the maker slide, then a piece that mates with that piece that is held on with a quick detach mechanism similar to a bike axle quick disconnect. I am pondering a whole re-imagining of my machine right now, but I just don't have time to finish it due to work taking all my time. Stupid job taking away quality Shapeoko time...
northbear wrote:Sounds like you have a good idea in mind, I like it! A disadvantage I can see with that kind of setup is adding plates will add more weight and also push the spindle farther away from the support of the v-wheels. Not sure how much this would matter. For me I think I will just start with the multiple z axis makerslide. At this point I don't see myself changing spindles all that often and so I am not concerned with it being a bit more difficult / time consuming. I will be interested to see your design when you get a chance to draw it up!

What if the current standard (and modified) spindle mounts were changed to bolt to the sides of the Z-Axis rail instead of to the front of it? So, in the picture below, mount the spindle mount using the rails shown by the green arrows instead of the red arrows:
