I took the list and went one by one, I had the number 1 switch turned on so turned it off. the only thing I did not know about is the JN1 and 2 so unable to check that. All else match the list. Tried running only the x axis in the jog mode. Did not sound good. Than ran x in the demo mode, still stalling, more so when starting and changing directions. When running the motor sounded good other than the stalling. Did the DMI and setting was 8128 matched the list. I did try changing the vol and acc but did better at 60 and 12. Changed drivers no improvement, change BOB no improvement. Checked connection no problems that I could find. tried checking the power when in stall but not enough hands. will do that with help.

I will try and test the volts.
I did buy another BOB and not change. tried the MDI but the motors where very slow and rough sounding.
I did use the 8128 but could not get motors to run very well. I tried those numbers after the ESS install and had to go somewhere around 7000 steps, velocity 60, accel 8 .  set the dip switches as recommended. still same problem. If I understand the ESS it does allow me to use 64 bit instead of a 32 computer and did upgrade to 64. should I go back?
I do not have a oscilloscope.

has been awhile posting but got the ESS installed,  set motor tuning to x and y/a.  can hold down arrow keys for x and y and motors run ok but when running demo they are doing the same thing; dragging, growling stopping. Did not help by buying ESS. Changed computers, no change. It doesn't do it at any certain line in gcode. I am very new at this and i'm sure I have missed a setting. Thanks in advance for any help.

Thanks

x running by itself sounds and does good.
Y and A by itself sounds ok and runs ok but not as good as the X.
Will barely run together and sometimes Y and A will stop and X will run very slow.
all three motors are long 34 steppers.  Is the 3.3 volts from the computer port correct?

my voltage from ports
port 2 ( 3.2)                                    10   (3.4)         when I hit the arrow key in opposite direction, only ports 3.5.7.10
3        (3,3)                                     11   (5)            went to 0 if that means anything.
4        (3.3)                                     12   (5)
5        (3.3)                                     13   (5)
6        (3,3)
7        (3.3)
8        (3.3)
9        (3.3)

Here is the final settings:                X settings
Y & A axis settings:                         steps 7100
steps: 6940                                    velocity 60
velocity: 59                                     accel    8
accel: 8                                          step pulse 5
step pulse: 5                                   dir pulse  5
dir pulse: 5

I tested by just running in the mach 3 demo and putting into jog mode. I will check the voltage at port.
