Hi all
In my on-again/off-again Hero 1 reburb project I've given up on trying to use the stepper motors for the steering, head and arms. Can someone suggest a good sized servo or setup to use for these? The steering motor shaft is pretty big (larger than 1/4" at least).
Thanks!

I don't think servos will cut the mustard. I have a Hero1 myself. I think it should be possible to get stepper motor controllers for those motors. What have you tried?
Google invenscience or torxis. Expensive stuff but you will never burn one of these out. I'm currently using them for neck pan and tilt. Way way overkill, but again will never have an issue with them
Sorry for not getting back sooner. Work and all. Attached is the stepper I would like to replace. It has a 9mm dia. shaft. I've tried the L298 board with no luck. Those torxis motors are huge! Might be a little overkill for me though.
I bought a couple of these... Robot servos They work great, lots of torque...
L298 board will not work with steppers. You need a motor controller specifically designed for steppers.
Sorry I can't provide a link right now, but if you search the forums, I believe Jeremie recommended a board that works with EZ-B that was good for stepper motors. Or, easier, just use the servos that Richard linked above.

Would that be the A4988?
Lol funny enough I recommended the L298, as it can work with steppers. You just need to pulse the coils in the right sequence. You'll have to use one channel per stepper coil. The L298 can do 2A per coil which is enough to handle some decent sized steppers.
Here's that thread
Yes the A4988 is a good choice as well, it's a very popular stepper driver
