Steel frame cnc router design/build

[CraftyGeek]

Thanks Jazz.
I have made a few changes since I posted that last image...the main one being the removal of the single leadscrew option. I've decided that I want to do a decent job of this, which means it'll take me longer to get it running - but the end result will be worth it...so dual leadscrews from the start - hopefully driven from a single motor.

I'm still very much tinkering with the overall dimensions - I have shrunk the z depth & reduced the overall height a bit as well.
I hope to have a bit more time to spend on it tomorrow to make some more changes, then i'll come back for another slap on the back of the head :-)

On the gantry you posted above - I assume that the spindle mounts between the *ahem* open legs?
Question...does the distance fore/aft that the spindle is mounted (relating to the x rail bearings) have any effect other than allowing the cutter to reach different areas of the table?

Yes just slapped some bearing and front Z plate on to show see pic.

Some would throw math's and moments of inertia etc shit like that at ya but in reality it's nothing to worry about really, so long has your not daft about it.
I just try to keep the overall weight balanced on the X bearings. Mostly It's just balancing act between losing or gaining cutting area.
