Sarcasm was
not the intent!
It was merely intended to be a parallel extension of similar exchanges between Ed and 8iowa earlier this week. It was also a reference to the blackbird 'event' in Arkansas earlier this week.
And the '.......Thanks' was intended to be the
only serious part of the post.
You be correct that statements made in jest can be interpreted as sarcasm by anyone misinterpreting the actual intent.
I for one am in favor of taking that risk in order to obtain the humor one gets from the 'jesting'. If any are mistakenly seen as sarcasm, that is an unfortunate byproduct.
Perhaps we interpret the 'Smilies' differently!:)

Oh yeah well I guess you know where I hope those black birds end up.
By the way you are welcome it was a good answer which is so unlike most of yours.
See Dusty was right!!!:D
Kidding!!

Ahh! But I included the smilies when reading those lines!
Sorry you do not understand!:D
BTW In spite of the description of ":rolleyes:", I do not mean it to be sarcastic. More of a 'I be misleading'. Think tongue in cheek!
Yes I will TRY to be good! No promises;)

To cut to the chase - further time and research into probable issues and fixes, brought about a complete replacement of all PowerPro components. Then both Wes and Jim McCann worked for a few days to figure the proper codes into the control panel. My supposition is these numbers are the "PID controller" (reference two posts ago)
What is most interesting to me is - although all new parts were in the headstock, motor pulsing was still happening. It must have been some kind of relationship between that particular headstock frame and the electronics.
Conversation with my Son (engineer making airplane parts) has told me the problems they have had with brushless motors have nearly all been Hall Effect and PID controller related. Reading (actually scanning) the link to PID Controllers has enlightened me toward Wes' problems of giving a fix to some problems over the phone.
Hi Chuck, glad you're back on line with your Power Pro!
I think you're right, PID controllers work in conjunction with complicated systems, and the overall response depends on many factors, and is mathematically involved with the infamous complex polynomial equations. The frame itself may have frequency resonances which differed between your unit and SS's development units.
It sounds like the PID system is facing a tall order in the PowerPro (huge speed range, wide range of load inertias) but can normally work when set correctly. I've mentioned elsewhere, I could imagine one day a PowerPro redesign in which different loads are managed with different sets of controller-coefficients.
Anyway, I'm in my 4th month with the PowerPro and I like it a lot.
