I was preparing for a Crusader II conversion on my mill, then I bought a
lathe with a Crusader M Lathe control that didn't work and converted that to
EMC.
The Anilam Crusader II and M that I have both use servo drives with + -
10V control and use tachometer feedback to the drive. The mill
Dear All,
I am using 5I20 and 7I33T to control the servo amplifier (SANYO DENKI).
When the turn on the emc, the DAC output generate a noise.

The noise affects the servo motor which always “shake”. The analog
velocity command of servo amplifier is using

I think you have a tuning issue.
PID controllers operate on error only, when there is no error the

Gentlemen,
With the cincikins.c file at www.mpm1.com:8080/cinci/cincikins.c I

I'm trying to figure out the best way to avoid missed steps especially in

Acceleration remains the same.
A rapid move at 7.5mm/sec (450mm/min) with an acceleration of 15
mm/sec^2 will take one-half second to get up to speed, and one-half
second to slow down again - 7.5mm/sec divided by 15mm/sec^2 is 0.5 seconds.

I spoke with Steve Stallings today, and he pointed me to this thread on
the Sherline stepper drive problems some of you guys are having. I
worked on this problem in late June of 2003.
Right before Sherline started shipping machines they tested them for
repeatability using a 3d contouring program

your Z is slowly creeping down, I bet some timing is wrong.
An acceleration or velocity problem with Z moving up won't generally

Loosing steps on change of direction is a relatively common fault, it
seems to show up more on Z axis, it's usually caused by having the wrong
pulse direction. If it's active high, invert it to active low, or vice
versa.

OK Thanks I can certainly do that. But
Thanks to Jeff and all those who have made this possible.
Even with my old obsolete Superior Electric drivers, I am now able to generate
working configs from Stepconf. Interestingly, on my router I had to invert the
step pulses on the X and Y axis but not on the Z axis to get them to move at
all.
And I will add
The original Sherline controller, and probably the current one
utilize a microcontroller to read the step and direction signals
without any external latching. This means that the direction
signal must be valid long enough for the microcontroller to
notice the step signal and

Everything was working fine until I upgraded to the Ubuntu 8.
Emc2 v.2.2.7 was installed with the cd.
Now I can't seem to get any output from the parallel port.
My computer is a Gateway E-Machine that runs the driver board.
Can anyone help me here?
Thanks

This is not correct since you asked for a relative (G91) move of
zero length (X0, Y0, Z0).
