Hey, I'm looking for a stepper motor that will have no backlash at all(is there even anything like that for a decent price?)
I'd like to use a stepper motor to control an automated focusing system, so I'm first trying to see if I can achieve anything without backlash.
I have a NEMA17, but as far as I understood it still has slight amount of backlash, I could use the stepper motor as direct drive, or I could maybe use belt drive and gear reduction. I think belt drive should slightly increase the torque, and lower the speed and backlash, but will it make the backlash 0? I have no idea....
I currently use A4988, but I plan on switching to TMC2209 which as far as I know should be better, but once again I don't know how much that would improve in terms of backlash.
There's also encoders, but I'm not all that familiar with that, if you think it could be useful and fits in the budget that could be an option.
I don't intend to spend so much into it, Looking for something around the ~$30 max.
Obviously, the cheaper the better, and if there is nothing in the $30 budget, what would be the cheapest option beyond that?
Any help would be much appreciated, if there is any further information needed please let me know.
