Title: Using solenoids for a plotter instead of other mechanical methods
Post by: goaty on June 24, 2019, 01:07:36 pm
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.)
