@Tweakie: Measuring it the old fashioned way using continuous mode on dmm.

That is what I expected. Unfortunately, you will not get meaningful readings when using a dmm set to continuity on circuits that are powered-up.
I suppose the bottom line is that if you suspect there is a problem with the driver then replace it with another.

Hi Sonolink,

Reduce current in stop state is the usual and recommended setting for stepper drivers.
Your machine looks good and from the very short video sounds good too.
I do not know the purpose of the Verify Position command or what the displayed indication represents.

There are many to choose from but I use a Warp9 ESS and that works well for me. https://warp9td.com/

How exactly are you measuring this 'short' ?

Choose a motion controller with good backup and support (not a cheap Chinese product) and the same for servo's and their controllers and all should be well.
It's not going to be a cheap project but I am sure the end result will be well worth the effort.

Or do you mean I should put the microswitches on the stepper to 1600 (200x8) and put "8" in Mach3 Motor tuning?

That is it exactly (sorry for my bad explanation).

Oh I see. That would mean I should set the steppers' microswitches to 1600 microsteps and put the same value in Mach motor tuning, right?

Thanks

No.
Set the microsteps to 8

There will be no direct 'short' between the Pul- and Dir- connections on the driver.
However, the internal opt-isolators may incorporate pull-up/down resistors so the measured resistance may depend on your measuring device.

I think an external motion controller would be a better choice than parallel port operation.

You would need to find details of the existing motors and drivers as they could possibly be OK to re-use.

It certainly sounds like an interesting project to undertake.
