Gents,

have a question on those famous cheapish AC servos form Aliexpress. Most of them are 17-bit absolute encoders. Correct me if i'm worng - this means it has 17-bit resolution per revolution? 1 / 131072. What for? is there any advantage of having such a big resolution per rev? i can imagine belt drive involed in drive - the slightest tension change in the belt under load will lead to position vs command discrepancy and force the motor to react. I think it will make the system nervous unless you set some parameter like dead band - but then why use such a big resolution?

Have anyone of you used those servos with Mesa cards and used encoder feedback from driver to Mesa?

Bit confused.

Hello,
Can the INCREMENTS be dynamic by G20 (in) or G21 (mm)?  

In my .ini / DISPLAY
INCREMENTS = JOG  .010in .001in .0001in
INCREMENTS = JOG  .100mm .010mm .001mm

Thanks

Thanks Rod, the external antenna was my next move.
I am in Sydney, any suggestion on model number that is known to work with LC2.9.4 ?

The Extender has been set up to use 2.4 GHz from the start.

The engineer in me wants to know why the failure in the cubicle.
I will do some more testing.
John.
