Ok - It's another day, and thank you for all the posts. Kind of answering the replies to my post:
1) Kent - thank you for the grandfatherly pat on the back. I could have done with a shot of scotch or something (even though I don't drink much!) 2) Kent - Google used to be my friend. Why ask the same questions that others have asked, when google can show you the answers? Google showed issues with 5i25 and g540 last summer/fall, but these trickled off to nothing. I had assumed that the issues had been fixed, that's why the "get the latest source and compile" attempt. 3) Marius - just an fyi - when doing stepconf on my mill back 18 months ago; the g540 charge pump disable was deadly. On LinuxCNC boot, the spindle would advance to full speed for a second or two; with charge pump enabled, this behaviour disappeared. The enable/disable is a little slide switch flush with the case. 4) Chris - as someone who did a large open source project, I know that one gets 99% complaints, 1% praise. From looking at the pncconf source last night, it was close to 10,000 lines of Python. Well done. Tempted to jump in, but Python is about the only language I have not touched, and so jumping in would not have been the best decision for any of us. 5) Sam - the xml files for the 5I25 were obtained from the link you specified; but (obviously, I guess!) it did not resolve the issue. Closer, but no cigar. 6) Peter - thank you for the hm2-stepper configuration hint. 7) Todd; I might just post the files, and I might end up doing that, but what do others who have the same off the shelf hardware do? 8) Andy - thank you for your detailed suggestions - much appreciated, and, I believe, ultimately will prove very helpful. So, I guess I'll re-group, and try again in a few days, now that I know that a new, clean, easy config is just not going to pop out of the computer at this time. Thank you; John A.
