Looks awesome!
I see a few improvements in your design that I will use if I start again with a new machine ;)
One thing I cant see clearly is the spacing of the bearings on the gantry sides compared to the spindle?
Its generally recommended to have the cutter inside of the bearings if you look from the side..
And it might be thats the case here.. but cant see clearly ;)

Hi Clive,
Thanks for the comments, much appreciated! I'm glad to know dual motor setups will work and I'll have someone to bug when I come across some niggles ;)
I'll try adjusting those motor mounts to see if I can shorten the screw - from memory, I think I put them there to have the motors embedded into the end of the frame (may not work, but its nice to dream - I'm thinking of adding cooling into there...) and I sort of thought having the nut mounted half-way between the linear bearings made sense - I don't suppose you happen to have any advice on placement?
Definitely will head your warning on the electronics - at the very least technology will have advanced somewhat before I'm ready to get them going! ;) I'll also try and run the numbers on the Ally profile.
Best Wishes, and a Happy New Year!
Thanks Nr1madman! I don't think theres anything too original in here, I've just pulled in ideas from a couple of people around here - its essentially intellectual theft! ;)
The spindle vs. gantry spacing is an interesting point; at the moment the spindle is just outside the bearing (see picture below), which I gather isn't ideal. Originally this was so I could get right up to the edge of the waste board - should I make the bearing footprint larger to encompass the spindle or is the current setup okay? If so - do you have any suggestions as to how far within the footprint the spindle needs to go?
Thanks!
Andy
