Is there a problem if the Eggbot is kept connected to the wall power source continuously?

No problem-- that should be fine, assuming that you're using the kit version of the Eggbot.*

If you're going to do this, though, you may want to adjust the motor current setpoint on the EBB to make sure that it isn't up higher than necessary.

- Start by powering up the bot and enabling the motors.
- There is a current adjustment potentiometer, labeled "CUR ADJ" on the
EBB. Turn the adjustment pot fully clockwise, which may take as much as
2/3 of a turn. You should be able to feel that both motors can move
freely.
- Turn the adjustment pot about halfway back. Ignore the noise, if any.
Trying to turn the motors by hand, you should feel some resistance now,
and that they can be moved in cogged steps.
- Adjust the pot until the motor(s) give moderate resistance to turning by
hand, which should be somewhat below where the motors begin making
squealing noise and jittering. You may find that the motors misbehave and
squeal constantly while your screwdriver touches the pot, so don't judge
the performance while the screwdriver is still touching it.



*If you're using a homebrew version with laser cut plastic, the frame pieces holding the motor do not have heat sinks, and may eventually overheat.
