Leadshine AM822 drivers purchased!

The COM port should be visible in the Leadshine software, as long as the adapter is plugged in.

Might be worth trying to uninstall the Leadshine software, then re-install it with the adapter plugged in. I've just downloaded the AM software and don't see anyway to refresh the COM port list, so I'm wondering if it maybe populates the list when it's installed.

Thanks, I'll give it a go.

Yes, I believe you need the AM882 plugged in and powered up for ProTuner to detect anything.

I've tried everything else. So it's probably down to my lead then.

I've used an old ADSL filter and removed all the components except the RJ11 socket. One thing I did notice on the RJ11 cable that I have is that the connections are reversed from end to end.

I'll try reversing the pins.

Fixed. Reversed the connections between the RJ11 socket and the R232 and all working.

Thanks to all for the help.

Drivers now powered with 625VA 70v linear power supply and everything working much better. However, I think I'm coming to the following conclusions:

1. The steppers I have have too high an inductance and/or are not powerful enough to perform as the original Superior Electric steppers did (even though their inductance was much higher and their power (on paper at least) was lower.

2. Steppers are probably not going to perform well enough for an industrial machine like this - they're just not going to be smooth enough for the type of fine work this machine is capable of. The latest version of this machine is fitted with servos and I think I'll eventually have to go down this route. Unfortunately, I know less about servos than I do about steppers.

I shall persevere with the set-up I have at the moment, but I think the steppers will find their way onto my 4th/5th axis project that I have planned.

I am very impressed with the Teknic Clearpath servos which look like very good VFM even with Sterling being so weak. However, this decision will require much further research and consultation on this forum.

Many thanks to all those who've advised so far.

How about a pic of the machine or a link model etc.
