I would be curious to know if your "jitter" problem also happens when you send the X, Y, and Z axes independently to Machine Zero ("Home" position). I think I had the same problem.

Move your X, Y,  and Z axes to some random location on your table. Go to the 'MDI' tab in Mach 3 and enter ('Input' text box) the following to send each axis to the Home position:
G01 Z0 (hit the Enter key)

G01 X0 (hit the Enter key)

G01 Y0 (hit the Enter key)
Then repeat the above process, but use G00 this time.
(F.Y.I. - G01 is a Linear interpolation move and G00 is a Rapid positioning move)

Did the jittering still happen?

Thanks,
Roger

I tried all 6 commands and they all worked perfect.
Tried again by just moving everything far from home and clicking "go to home" and all axis violently jittered home.... Makes no sense, hopefully the script above will be helpful in solving my problems?

Thanks guys
David

had a quick look to your XML looked ok so far.
interesting would be the code of your Ref All button.

Here is the script.

Hey all,
I have a EZ-router scorpion black 2011 4x8 cnc.
Have had it in storage for a while, just got it out and have been cleaning it up.

Whenever I reference all axis the Y-axis seems to have some major jitters, sometimes the x and z as well, but mostly the Y.
I attached a video showing the y axis with the gear not even attached to the table.

I am using the XML setup by ez-router when you purchase the machine.
After it reffs home and jitters its way there I can run Gcode and its perfect, no issues.

But when I "ref all" or even "go to home" it jitters it way there.
Any ideas? I will also attach my XML below

On mach3 R3.00

Thanks all.
