With the setup you have now then getting 5m/min would require a kernel of 65KHz (actually 50 but 65 the closest above)
So set your kernel to 65KHz , set motor tuning t 5000 velocity and restart Mach and see how it performs.

Just checked my g320x's re the torque trim pot.seems that the early 320 x's (3-4 years old)were more amps clockwise as the original 320/340 but there seems practically no difference where you position the pot on the recent ones (about a year old) although they do seem slightly stronger in the fully ccw position
  Is there any more info on this,can anyone confirm my findings?

Hello,

I tried as you told me Hood, 65kHz and 5000 velocity,  it is nearly the same thing.  on my amp√®remeter it shows that only 5A that the motor takes.
when I put the current trimpot more than 11 o'clock  I have immediately a short cut and the fusible comes down.
so what do you think if I mount the pulley of 20 teeth on the Screw and the other of 60 teeth on the motor itself for having more speed?
it will be OK or a very bad idea?

I have forgotten some thing, when the servo motor runs without the ground of the encoder it runs very fast, but mach3 of course does not control it. it runs only fast, one direction , that's all. I found it very strange. It should runs fast with mach3 too, (normally) so strange, is not it?

Ok can you have a look on the diagnostics page, are there any limits active there?
What does the frequency say?
What does the Time in Int say?
If you go to the tab screen and press X+ what does the Units Per Min DRO read?

You seem to have a lot of axes set up, are you using all 6 axes? If so what for?

Hello Hood,

first no limits active.
frequency is 62800
time in is about 5.9 to 6.1

when I press X+ unit per mi DRO is 4830

Axes are, I have a gantry, I will send you some pics, so 2 axes for Y, Y, Z, and and also A and C for turning Wood, but I guess later..

for now I am working with X axis if it will be OK, the all other axes will be the same

Thanks Hood

Ok that sounds fne regards frequency and time in Int.
Regarding the jogging, that also sounds fine as that is more or less what you have set for the X. Does the motor not turn at approx 1500 RPM when you are jogging?

Regarding multiple motors on axis, you should be slaving them, thats done from Config menu then Slaved Axis.
