Slow Linear Actuator for Record Cutting

Hi everybody,

I am trying to built a record cutter - but I am a programmer, not a metal working gal. I need a slow moving sled I can mount my cutter head to - around 1" per minute - controlled by a stepper. I am not sure if a tooth belt would achieve the slow and steady motion necessary to continuously lead the cutter head - so I think a lead screw system would be best.

Maybe you can help me with your ideas?

Thanks.

Michaela

Yes. Lead screw is good. Gear the thing down with a high ratio gearbox. Since you're moving continuously in one direction without reversing, backlash in the gearbox is not a big problem.

Microstepping is also going to help. Look that up.
