BTW the bug Peter is talking about is one dead click on an MPG (Art has looked for this 2 times and not found it).. Hardly anything that will make you see lost steps on the machine..

So Peter, Other then the dead step on an MPG over ModBus what are the over a year long standing bugs that have you upset?
Thanks
Brian
Brian,
I'm disappointed, more than upset. I don't have all my emails with me at the moment , but as I recall the last post by Art was that he said he had been looking for a problem that didn't exist. (to do with the timing tick counter), and not the one I was reporting. This problem has been around for a very long time, much longer than 12 months. In fact it must have been well over 12 months ago that I sent you a ModIO and LCD display so that you could look into the problem. Has the ModIO ever been off the shelf and used?

The problem is NOT "one dead click". As I have described on a number of occasions and produced a video to demonstrate the problem, The issue is to do with an axis not moving when the calculated MPG velocity is less than 1.
http://www.youtube.com/watch?v=M2TBe1DU4HcIf the calculated velocity is 1 or greater than the axis will move, otherwise it does not. One of the purposes of an MPG is to jog the machine to a position. It is very frustrating when you are very close and you move the MPG slowly as you come close to an edge, and nothing happens. so you then need to move the MPG faster and suddenly it moves, overshoots with varying consequences. So please don't dismiss it as "one dead step". From the symptoms of the problem, it would appear to be a rounding error, maybe to to with float to int conversions.
Now both Terry, and Andy have reported issues with the MPG operation. I also have other reporting the same issue. I understand that for whatever reason, this is very low on your priority list, and as such I find it difficult to accept that it will probably never be addressed, as there will always be a new set of "bells and whistles" to add.
Peter.
