I did'nt install version 11, but did'nt have any problems with
version 10.
I tried changing all G0 commands to G1 and havn't lost any steps
since.
How is the speed of a G0 move calculated ?

Art,

I have also noticed what seems to be a decrease in performance
(missing steps). Started for me at version 11. I had to retune

(slow

down) on two different machines.

On an old 600MHZ PIII, I no longer run at 25KHZ - it has dropped to
23KHZ? If you have a old version 10 I could try and go back -
unfortunately I deleted my copy. On my faster machine 1.6 GHZ,

there

is no noticeable change in frequency but the rapids had to be
dropped by about 10%.
Just food for thought.

Rab:

G0 speeds are only calculated from the motor tuning. This is one reason you
must be carefull is using 35 or 45Khz, any touble and you will revert back
to 25Khz and without retuning, your rapids will be off.
