Looking at building a table that has over a 5ftx12ft travel, with a gecko 540 controller. Main use will be plasma and laser cutting, with possibly a dremel thrown in for cutting some mdf for speaker boxes and such.
Wwould way say its going to be moving about 70 pounds.
Controllers and all can be change, I just like how the 540 is all in one and seems to have a decent amount of support and following. I also like that a 4th controller is built in so I can use the plasma possibly as a tube notcher with a spinning axis.
Obviously not using ball screws.
3 of http://cgi.ebay.com/NEMA-23-Stepper-...4#ht_500wt_928 possibly work?
