Using solenoids for a plotter instead of other mechanical methods

If your movement on your plotting machine was purely magnetic, wouldn't it be more accurate than say with belts, cogs, and worms?

My machine planned is going to brush up against a nichrome wire to get its absolute position - but other than that, if it was just purely arriving at the destination via a solenoid it would have no other machine in the chain to get to the position.

So, can you make solenoids that go over a space of 50cm?   but even if that's not the case,  getting 10cm would already be enough if you were going to be making a ram chip or cpu with it.

Yes, its called a stepper motor.

As long as you gear down, (not necessarily with gears), you can get great precision with a mule-drawn cpu making device.  O0

But stepper motors seem quite good.

A stepper motor is basically a rotary solenoid.

Thanks for the replys.

So stepper motors can already step a nanometre?     I spose that's how they make standard micrometres…  ???
 (as in mechanically, with cogs,  not just purely magnetic.)
