Hi,
I am confused by an odd stepper problem which I can't understand. The 
    stepper affected is the one driving my rotary axis and the problem
    is 
    that it won't go fast enough... To explain - if I issue a G1 command
    in 
    MDI, I am limited to a F20 speed as, beyond that, the stepper gets
    very 
    jittery and loses steps (at F40 it gives up altogether). However, if
    I 
    issue a G0 command, the stepper whirls away happily at 3 or 4 times
    the 
    speed and doesn't seem to lose steps at all (i.e. I can send it one
    way 
    and then the other and it returns to where it started.). So, what is
    the 
    difference between a G1 command and a G0 command and how can I get
    the 
    G1 speed to increase reliably up to almost the G0 speed?
    I'm running the latest version of EMC2 on Ubuntu (unless I've missed
    a 
    service release in the last 2 weeks ).
