Not really...I was hoping to get a servo package that could connect directly to a controller...for example the stepper motors I have came with a cable that plugs directly to a card.
Is this common when purchasing servos....(yes servos are required...feed rates are just not enough with steppers during interpolation))More or less, it depends on what kind of board you're talking about and what kind of servo drives. If you use Gecko servo drives then the control loop is closed in the gecko drive, but if you use something less intelligent like an H-bridge driver then the encoder signals are routed back to the control board, like a Mesa 5i20 or 7i43 or a Pico Systems board.Is the set up the same when building a servo driven system as a stepper? ie...cables from motor to board... then LPT to PC?...any ways this is the way I wanted to go.Part of it boils down to your choice of control software. If you choose Mach then your choice of hardware is limited by the fact that Mach doesn't have the facilities for closing the loop in the PC software. If you choose EMC2 you can still choose Gecko servo drives and run it like a stepper system but you can also allow EMC2 to close the loop itself. If you are using high count encoders, you will probably want a board that supports encoder counting in hardware. The PC is really not up to counting high encoder counts at high rpm.
Will be building a small mill/lathe combo....(I want to turn parts then machine them)
