SO my rebuild apparently is wrong, my product is now being carved undersize.

Run the Axis Calibration feature (Settings page) just to check that you have your Steps per Unit set correctly for each axis.

You may have acidentally corrupted your .xml profile. Try returning to an earlier profile which was working correctly. Operator / Restore Settings  (follow on-screen directions)

You could possibly try to reduce the axis Velocity in Motor Tuning and then reduce the Kernel speed - bit at a time, trial and error.

Try a much improved (lean and faster) PC.

Perhaps download and install the current version of Mach3;  https://www.machsupport.com/wp-content/uploads/2013/04/Mach3Version3.043.exe
(There were a number of issues with version .066 and it was withdrawn)
Make a backup of you existing Mach3 folder before installing the current version over the top of your existing version.

I don't think the Mach3 Parallel Port driver was ever intended to support a 13000 units / min feed-rate so the only real solution is an external motion controller (13000mm/min is something I have never tried).

I must say without forgetting.  I installed mach4 demo hoby and tried it there was no fluctuation.  feed rate was fixed

Not really a fair comparison - if you had also installed the Mach4 Parallel Port driver plugin / motion controller the results may well have been the same as they were with Mach3.

The ESS details are here; https://www.warp9td.com/
The G540 details are here; https://www.geckodrive.com/g540-4-axis-digital-stepper-drive.html

(They are not the only quality products available but I use them both and the manufacturer's backup and support is second to none).

If the Mach3 (on screen) feed-rate varies when the Parallel Port is disconnected that would indicate that your PC is not up to the task of providing the necessary pulse stream fast enough.
The Parallel Port is really not that brilliant when operating at high kernel speeds so it may be best if you consider using an External Motion Controller. There are many to choose from but avoid the cheap Chinese types. The ESS from Warp9 is good and that will operate with Mach3 and also Mach4 (if you need to move on from Mach3 at some time in the future).

Only you can decide if Mach4 is the way to go but as mentioned earlier the ESS from Warp9 and the G540 from Gecko would be a good combination which are good for both Mach3 and Mach4.

Port 3 Pins 2 through 9 can be configured as Inputs or Outputs. Check your settings in the ESS General Config. to make sure they are set to IN.

Sorry, but it is as I suspected, that board will not operate with Mach3.
