General Mach Discussion / Re: Help with jerky motion - again!
« on: October 02, 2018, 04:03:32 PM »
Hi Gerry and Tweakie,
Thanks for your comments on this.
I have now resolved the issue.
Gerry's hunch was correct, it was the Pokeys controller.
I opened a ticket with them and they were very helpful and went through the problem with me.
The Pokeys software comes with a really helpful troubleshooting feature. This showed I had slow USB communications, at approximately 8ms.
The issue ended up being related to the USB drivers I was using.
As it turned out I couldn't fix the problem using USB.
The solution ended up being for me to use the Pokeys ethernet input instead of USB.
The troubleshooting feature now shows a communications time of about 0.5ms and this 16 times speed improvement resolved the jerky motion.
Thanks again for your help.
best regards
Craig
