Some Notes On Kit Configuration and Pricing

All kits are sold as 2 separate entities.  The Mechanical parts bundle, which includes all of the mechanical assemblies, extrusions, plates, nuts, bolts, screws, etc. is sold as a package.  Electronics are identical no matter what mechanical package you select, and are sold separately.  You need both the mechanical parts package and the electronics package to make up a complete machine.  Options for the machine bundles are generally extra cost items, and some examples are listed with each machine specification page.  Ask for a custom quote to get pricing on these option packages.

Openbuilds Bundles come complete with extras like cable chain, wiring kit, homing switches, router mount with LED light ring, and spoil board mounting hardware.  Generic kits are similar but do not come with these parts standard, they must be added separately.  Openbuilds offers a generic Electronics package that includes most of these parts including wiring and switches.  Generally these parts are included in the prices custom quoted for Generic Packages.

Budgetary pricing for all machines is shown in each machine description, near the bottom.  Note that these prices are approximate and may vary with shipping costs, US Dollar conversion, etc.  Ask for a custom quote to get the most up to date pricing.
