Dual screw design, I am working on building my machine right now- it will have dual 1/2-10 acme, belt driven. I have some mock-up pics of the drive layout in my build log. I do forsee some issue with the screw alignment, I have designed in enough adjustment so that i should be able to get it set up well.
Remember that the motor will be seeing about twice as much drag in the system as opposed to a single screw- spec the motor- i am using a 640oz/in @ 50v. |
