Router Build number 2

[charlieuk]

I'm trying to decide how is best to do the stepper mounts to include a belt drive to each of the ball screws.

I was going to have them on the side but that will increase the over all width a fair bit

I was all so wondering if there is a way I could have the motors inside the main tube but not sure its a great idea.

any one have any ideas or suggestions ?

Structurally/mechanically ok but need to get cables to the motors plus best to put holes in the mounting plate and maybe box section as well to allow for cooling.

yes, I was thinking I would probably have the mounting plate welded on the end and then have a hole in the side to post the motor in and allow it to be mounted up, just hoping there will be enough room to get the pullys on doing it like this.

the other think I'm just trying to think about is mounting the ball screw blocks, and having a method to adjust them a little if needed so rather than mounting them direct to the steel have a plate in-between them with some elongated mounting slots?

I don't think it will be a good idea to weld a plate on the end.
How about making a motor mount with the appropriate centre hole and elongated slots made out of ali and make it wrap around the box on the outside left and bottom edge. That way the motor can be fitted to the mount and then slid into the box and bolted through the flanges of the mount into the steel box section.

do you mind explaining why not?

this is what I had in mind, could easily add extra cooling around it and then would print some cover with mesh in to prevent crap going in.

Ok that looks fine if you can wiggle the motor in there I would think you will have to mill out the steel plate so that the motor would be inlet into it because the motor shafts are generally not long enough for the pulley.

[charlieuk]

yes I have that recess drawn in there it should be fine getting it in and then will just tap the holes on the motor



like I mentioned I'm a bit worried about getting the bk blocks all lined up so thinking maybe make some plates up like in the pic just to allow 1.5mm ether way incase the holes are not perfect. but now just thinking maybe I would be better making a bracket from angle ali and using a fk support instead?
