    Hypothetically, If you were making a metal rack could you cut it to suit other belt sections

    apparently the Gates powerdrive profile works too
    found this thread on cnczone.

    I am going to glue the base belt down with double sided sticky tape (sailmakers version)

    yes good point, im probably going to have the belt teeth vertical ..... probably... but that is yet to be decided 100% so.....



    Thanks Ger21, i will look through at your system

    I'm pretty impressed with Mike Everman's Servo Belt concept. I first ran across it in the threads on CNC zone Gerry refers to. There more on it on Everman's own blog at http://mikeeverman.com/. It seems like a great solution to the problems of belt stretch in conventional systems and the limited tooth engagement and resulting low shear strength and backlash compensation I see in CNC fabric cutters like this: http://carlsondesign.com/plotter-cut...plotter-cutter.

    What about making the belt on the drive motor side a continuous loop (tank tread) and skipping the full length top belt? If you mount the belt system upside down, similar to how you see racks mounted on many CNC router axes, the protection from dust or chips seems unmerited.

    Have been planning a moving table router and wanted to try a Servobelt design. I had some Vexta 5 phase motors with 10-1 low backlash gearboxes which I wanted to use. Wanted a sort of modular self contained drive that I could bolt onto the frame, I shall be using a dual drive and will sync the drives with a shaft between the motors.

    The std. 37mm OD bearings are assembled on steel tubes for alignment, they act as spacers for the side frames and are clamped together by the mounting bolts

    The engagement with the belt on the table, is set by the outer bolts in the chassis having slotted holes in the frame. The belt tension is set by moving the motor in the slotted holes in the chassis plates, also carries an outrigger bearing for the 18 tooth pinion.

    I have carved a setup out of wood before I waste any aluminum
