You say that for the internal diameter 'all you need to do is to redefine the orientation number' but you don't make it clear what that means and how it's set.

I've just watched the setup video on Youtube and it makes no mention of enable signals at all.

I don't know if this is the right place to post this, so please let me know if it's not appropriate.

I have a machine that already has a CNC control and AC Servos and I'm swapping it over to Mach3...

I just found a link to the USB isolator I used.

This is an expensive thing to do. I bought a fibre optic extender for another application so used it for this because I was having so many problems. I had a quick look on the net for the one I bought...

I think you can select if it's active high or active low in one of the setup tabs. It should pull down very close to 0v if it's set up right.
You need to give more detail about the enable input...

Answer is in another thread.

I'm told that your postings should now go straight onto the Safeguard Robotics Forum without delay.

Here's Bruce's response...

"Hmm. Will get this forwarded to someone to take a look. That isn't supposed to be anywhere on the forum. We want it open!"

I'll take that up with Bruce, it doesn't seem right.

It something I'm looking closely at for the CNC Brain but it's far to immature to risk doing anything yet. There's an industrial version under test so I want to see what that offers.
Another issue...

That's strange, I'm not aware of having to wait for a post to be approved on the safeguard robotics Forum. I've been posting regularly for about 6 months without any delays.

That's a fair comment...

Sorry, I didn't read all your last message.

The inputs to the isolator board are driven by whatever you connect them to. In this case you presumably want to drive outputs from the CNC Brain so you...

Don't worry, the other one is just fine.

You might want to look at this isolator board as an alternative.

It's only a 4 channel board but you can always use 2 as they are quite small....

I don't know what's available in New Zealand but I did see an 8 channel board which used ULN2803 drivers or similar driven from something like ILQ74 optos. I'll see if I can track that down.
Here's...

You have reached the end of my knowledge on this I'm afraid. The Device Instance on mine is USB\VID_0FBB&PID_8014\6&18F52E03&0&3 which I guess is a unique system generated ID for that instance of the...

I've just checked my XP machine and it has the CNC Brain installed under 'Unisversal Serial Bus Controllers' as 'CNC Brain'. The driver is accessed from there.

I presume you mean the files that...

As far as I know, you just unplug it for say 1 minute and that's all. I would be inclined to force XP to uninstall the device and see if it will work correctly from scratch.
If you go to device...

Does the unit work if you have only the USB port connected ie without any encoders or connections to M1 or M2?
The PC will earth the 0V on M1.25 and M2.25 and you will have huge stability problems...
