Gate / Bridgeport Interract / Project

[kingcreaky]

Following this, I was left with little choice but to bypass the feed gearbox, by hanging the motor directly off the main lathe input pulley, and put up with the lack of torque.

This enabled me to produce a new motor front





however, despite my best efforts, its clearly not aligned perfectly, as I can feel the stata grind when turning the shaft manually, either that or the actual shaft or casing was bent when it dropped? Disappointing but I learnt alot, managed to brake my lathe, and lightened my wallet to the tune for £65 on ali. Nevermind

so... I bought a "new" motor (£22 off the bay, 2.2kw)



havent yet fitted it, but it is face mounted, and has a long shaft, so I dont think it will be too difficult.


As for the machine, with thanks for the Dean, I got the servos working.

The servos have 10,000 steps per revoloution, as im driving the ballscrews via 2:1 ratio, and they are 5mm pitch, I make that 4000 steps per mm.

My old faithful parrelel port, cant keep up with that kind of resolution so komatias kindly sold me a ethernet smooth stepper.

I mounted the control box to the side of the machine, using rubber mounts, and made a bracket to mount the monitor keyboard and mouse.









and albeit, not yet including home switches, limit switches, a spindle motor or coolant, the machine is moving



listen how quite those servos are compared to the z stepper!
