I can see why you get so many steps per unit.  These gear reducers really 
step down.  I've got several Vexta's with gearbox but haven't figured out 
how to use them.  They seem to run fine with the Gecko drives but I'm 
using about 50 volts.  What is your power supply voltage?

Well if they run at f10 okay you could set 

[TRAJ]

DEFAULT_VELOCITY =      0.0167
MAX_VELOCITY =          0.167
DEFAULT_ACCELERATION =  5.0
MAX_ACCELERATION =      5.0

and in each axis you will need to set 


[AXIS_0]
MAX_VELOCITY =                  0.167

You should understand these numbers as units per second.  You can 
calculate max velocity by dividing the feed per minute by 60.

> what does AXIS SPEED represent ....is it the feed rate

Axis speed on the gui is the jog feedrate.  It only makes a 
difference in manual mode.

> what does FEEDLIMIT OVERRIDE represent....

Override works in any mode and is the percentage of the programmed 
feedrate that you want the axis to run.  For example, if your feedrate 
was programmed to f10 then a feedrate override of 50 would reduce that to 
5 units per minute.  Feedrate override of 120 with the same feedrate 
(f10) would mean that you would be running 12 units per minute if that 
was not faster than rapid allowed.

You can reduce a rapid or a feed using it.  You can not increase a rapid 
past 100% but you can increase feeds past 100 up to the rapid rate.

Hope this helps.
