Yes I did restart. I guess it is a wait and see.
I restarted Mach, I didn't reboot the computer.

I checked the step out to X, Y & Z with X & Y set to 2000 and Z set to 1000 and they were all the same.
So I set X & Y to 1000 and there was no change and a 1" command moved 1".
Your guess is as good as mine.

Hood,
Those five boards were in the main card cage when you open the side cabinet. Just to the right of that card cage would have been the 12-, 12+ and 5+ power supply. The 3 SMD & 1 ACC & 3 axis power transistor blocks would have been on the right end of the cabinet on the door that opens to the back.
They might still be there.

Well that doesn't explain what I am seeing. My electronics don't have any provision for anything except full step.
Yet two of my axes are now running set at 2000 steps per inch and the third is set at the normal 1000 steps per inch.
There has to be a bug in Mach 3. I am going to get my O scope on it maybe tomorrow.

You are correct. That is why I said that Bridgeport (at least the US model) was full step only.

Hood,
Did your BOSS 6 have 3 SMD cards and an ACC card mounted on the right hand side of the main card cage cabinet? If so it was definately silgle step.

Now I am going to have to set the oscilloscope up out in the shop and check the pulse streams to see what is going on.

Hood,
I see the difference being that your mill is using metric ball screws where all of the ones that I have worked on were 5 turns per inch ball screws.

Nickle,
I have been using Mach 3 for about 1 month and I haven't had any hickups yet. I am running Windows 2000 on the computer on the mill and I haven't bought a license yet because I am still testing like they said to do on the web site. I mostly like what I have found except for the need to have a mouse. I am working at getting things set up to work from the keyboard much like the AHHA software does.

The difference between BOSS 6 and BOSS 6.1 was in the Bridgeport software. The Iron was all the same for the Boss 6 mills in the same series. (Series I or Series II) BOSS 3, 4 & 5 iron was mostly the same different in electronics and software.
Did you change motors? I have been doing tech support for Bridgeport CNCs for the last 18 years and the 6s have all been 2:1.

Actually your BOSS6 was full stepping with a 2:1 ratio on the belt drives. The SMD cards are interchangeable between BOSS 5 & BOSS 6.
I have used other software and it was always 1000 per inch. It has to be Mach 3 as that is the only change.

It was a BOSS5 and yes I am still running the Bridgeport SMD and ACC boards using an interface board that takes step and direction and converts to what is being called "Wave Drive" here.
What is puzzling is why Z is still 1000 steps and X & Y are 2000 steps when with the other software all are 1000 steps.
The driver can't be sending 2000 step pulses per inch or the mill would be moving 2 inches and there is no 1/2 step setting available.
