Question How do I calculate the ideal travel distance of the ball screw per revolution of the stepper / per step for the following hardware (I believe this is called the lead)?
Background I have a pre-built 100mm Ball Screw Drive Linear Slide purchased from Amazon.
The specifications of this assembly are as follows.
Boundary dimension: 40mm
Shaft diameter: 12mm / 0.47inch
Rated vertical load: 40KG
Rated horizontal load: 60KG
Effective stroke: 100mm / 3.9inch
Ball screw length: 165mm
Sliding block: 60 x 80 x 30mm / 2.36 x 3.15 x 1.18inch
Pitch-row width: 68mm (max)
Pitch-row length: 60mm
Slide table size: 190 x 40 x 20mm / 7.48 x 1.57 x 0.79inch
Weight: Approx. 1432g
The stepper motor included with this module is 42BYGH48.
Looks very similar to the ones defined here with the same wire out colours. Looking into this I found multiple sources refer the desired number this as the lead (lead is the linear distance traveled by the nut or screw after one full rotation). Page 2 of this source talks about this but I don't really follow where these numbers have come from.
Can anyone suggest a good source to help explain to me what I need to calculate this for myself? What values am I missing from my setup to calculate this?
Sorry, I suspect I'm thinking about this all wrong and look like an idiot! had a long day at work and just spent an hour digging around and made no progress! I was certain someone here could point me to exactly what I needed!
