I am running a GCODE, for operate  wheel of sewing machine in an embroider project. 
In this moment Iam using Z axis for this movement,  until I change for A axis. 
My set up of Z axis is in this way
Steps x Revolution = 800 (200- ΒΌ microstep)
Mm x revolution = 10 (simulated)
Steps x MM = 80.
Vel    3000 mm/min
Accel = 500 mm/sec/sec
I created  two variants of CGODE Lines
For two variants F = 3000
1-G00 Z10----------In this case 100 first lines runs in 59 secs
2- G01 Z10---------In this case 100  first lines runs in 45 secs.
I think that  GCODE with G00 in Z movements should be more faster than second variant.
What do you think about that? 
Thanks in advance, sorry my bad English.
