The 400 steps thing is an example I believe. I’d thought that the SO3 motors were 200 step units (though maybe this was changed?). The number of steps per revolution going to 40 from the original 20 is a result of the micro-stepping default increasing from 4x to 8x.
Using the 200 step premise w/8 microsteps nets perfect movement using a 1.575" per revolution displacement. If the motors are really 400 step capable I could halve the displacement and double the accuracy…
No, motor steps are a function of design / winding — you can’t change / configure for that after the fact.
Thanks for mentioning this, I’ll have to see about re-wording it.
You could of course, replace the stepper motors w/ higher resolution ones (so long as they have compatible torque and wiring and are the right size). I have 400 step motors on my SO1 and the additional precision is quite nice. Need to rework it to have GT2 belting though.
thanks for clarifying… I understand the motor properties and I’m fine with the existing stepper motors. Everything is operational regarding CNC motions/controls with the 200 step/rev and the 1.575" displacement. I won’t be needing more than my net 0.000984375" movement capability for awhile.
