Aluminium CNC log.

Looks good, except for one thing. You have put the rails for the Z-axis on the Y carriage. It's much stronger if you have the bearing blocks for the Z-axis on that carriage (in addition to the bearings for Y). I mentioned it in post #23 and #60. Although having said that with the way you've orientated it it wont make too much difference.

If you don't mind me asking, how much did it cost to get those bits cut?



Erm, post #53. Same wire for steppers and spindle to VFD.

Cost around £325 for the Aluminium and to get it cut perfectly, there are cheaper places but I was inpatient.

Mounting the rails behind the spindle plate in my Eyes isn't correct.
I don't know why it would be stronger and on our scale machines it may make no difference at all but I just prefer it that way.



I know this drawing is unfair but I'm provin a point here.

Also, Once apon a time, my college used to be the place people went for engineering apprentiships, While all the CNCs and most of the lathes are gone now. I managed to find about 40 brand new end mill bits in the sizes 6mm and 4mm. These fit perfectly into my Spindle and my tutors said i could have them :)

And I'm going to buy a reel of single core wire between 1mm^2 and just use it for everything. I would go multicore for the steppers and drivers but I don't need a reel of it costing nearly £100 from Farnell and don't know where else to get cable.
