Lichuan 4 axis stepper need help-

Hi guys. I've spent the morning having a go at getting a 4 axis ethercat drive working.
Just the most basic config I could devise from Dominic's sample.
I got movement from the first drive but its not right. just a whine and a bare stutter.
I wondered if one of the phases was the wrong polarity but no luck with that. The same result which was odd.

There is a windows USB config program which let me set the motor amps to 2 amps and I could see the steps/rev was 10000 which seemed high.
Any ideas would be appreciated. They are a good solution if we can get it going at USD $92 + shipping (for 4 stepper drives - $23 each stepper)

Sorry its from Lichuan. They also have a closed loop one too

I did check, i can not find anything from Lichuan on Amazon.de, bloody hell, this would have easily been the thing to suck me into EtherCAT, but nooooo...

They have listings of sets with the drives on Aliexpress but I messaged them direct on Alibaba to buy the drive. Had it in about 4 days ex China via DHL.

We have to get this going as its soo cheap!
