Sure if we worked day and night for a week we could build you a fully wired and tested machine to your order specs, but why would wee need that pressure. ( I've Made that mistake in the past and have the high blood pressure to prove it)
I have a small shop with limited space so each large machine must be built in order, and when i get an order, i usually have others already half built. It also costs a lot of money to buy the Linear bearings, motors, cable chain, gear rack leadscrews and i don't buy from china (except all motors are made in china now).
What your assembling in a weekend must be a very basic machine with the controller and wiring all ready to go. Do you think you could assemble a Techno 4'x8' in a weekend ?? Hardly. You could put a model car together in a night, but a real car would take you a year !
Check out our 4'x8' machine. If you can assemble it in a Week, Your Hired!
