The major components arrived this week, from China and USA. Switches, and other components which go “ping” will be bought locally as required. I am hoping that existing pulleys, belts, brackets will be adaptable.
The motors to drive the X, Y and Z axes are 1.2kW AC servo motors which can be connected to single or 3 phase power. Each one weighs 6.7kg (14.7lb) . From China, they are nicely finished. Substantially shorter than the old servos which they are replacing and slightly larger diameter. I am hoping that the slightly larger diameter will not cause major problems.
And each servo motor came with a controller and cables and connectors.
And the electronics came from USA.
All up cost so far is ~$AUD2100, of which shipping is about 25%.
Next step is to swap over the servos. The old shafts are 16mm and the new ones are 19mm. I intend to machine the bores of the pulleys. Hope there is enough
meat Tofu to allow that.
