Beginner - Motors

Hi all

I'm starting a new project whereby I'll want to use 2 motors to move two sliders specific distances (a few inches) using a worm and rack setup

I've not done any pi hardware stuff, will I need stepper or normal motors, and I'm assuming I'll need some sort of board in between so that the motors can have their own power supply?

I'm looking through tutorials but some assume more knowledge than I have (for Arduino veterans etc) and I should probably know what kind of motor I'm wanting to run first

Sorry this all sounds so noobish... any insights would be welcome though

Use steppers if you don't have feedback about the distance moved.

Steppers rotate the shaft a fixed amount each time you command them to move. Ordinary DC motors rotate the shaft as much as they can.

Ah cheers, Yeah there'll be no feedback, so that sounds like the way to go
