Thread: Hi from long time loiterer
Hi all, well its taken about 2 years to decide on what's needed and to finally put it down on paper. It needs to be able to cut ali and carbon fibre.
Basically i've decided on a footprint of 1500x1000x500mm with a cutting area of about 1200x800x250.
Ill be using 20mm supported rails pn all axis with a view to upgrade to profiled rail later down the line.
Im hoping i can make the whole thing from ali profile as i dont have facilities to machine parts without farming it out. The rails should bolt straight to 60x60 profile. But the bearings will be a different story. Ill have to work on that one.
All axis will be driven by ballscrew with dual screw on X axis.
Has anyone used MA860 stepper drivers on ebay? http://www.ebay.co.uk/itm/2510949318...84.m1423.l2649
I'd like to hear your thoughts on them.
Stepper motors havent been decided on just yet.
Im working on the idea of 2 PSUs (70v+) but may be an overkill
Spindle will be of the 2kw w/c variety.
Hopefull ill get a build log up soon.
