Siff' Build Log

[everyreasonto]

Thanks for the input guys, I really appreciate it. I hadn't seen the seller linearmotionbearings before.. boy is he cheap! I'm really liking the look of the machine you posted Jonathan but wouldn't I need two ballscrews and two steppers on the X axis?. looks like I could get a larger machine for the same budget, using the supported rails that everyone seems to be suggesting from linearmotionbearings. The rails I put in the original plan were 16mm so I guess I overestimated their strength.

Budget is my only constraint, excluding spindle, I have about £1000 to spend.

Taking advice on the stepper drivers, I've found some from a seller called cnc4you. I also intend to get my steppers and ballscrews from there.

EDIT: Looks like i'm going to go for this set: http://www.ebay.co.uk/itm/3-SBR20-se...#ht_1004wt_948. Would work out around £450 shipped (inc tax) and they are all 20mm rails.
It would fit very nicely to the 60x30 profile from hepcomotion.

I'm going to make a point of avoiding Valuframe extrusion because they said that delivery would be £33 + VAT if they were sending to a private address, robbing gits!
