Peter,
Do most Mesa stepgens have the same limit?
JT
~164 usec is the longest on cards with 100 MHz ClockLow =
7I76E,7I80,7I90,7I92,7I93,7I94,7I95,7I96,7I97,7I98
Cards with 50 MHz or 33 MHz ClockLow will have ~330 usec
or ~500 usec maximum timings.

I would think 50 usec would be ok for the slowest hardware
The stepgen firmware has a limit of ~164 usec for all timings

Hi Chris,
Can you increase the step timing to > 12,000?
"When I was using the parallel port, the step and hold were 12000 and
3500. The software maxes this out at 1 for the 7i92 so I used that
instead of 12000.
X axis will move, but NOT very smoothly. Y and Z do not move at all.
All 3 axis are identical, with the exception of the length of the
leadscrew (china cnc3040 machine). Same motor, same leadscrew pitch,
same wiring, etc. The motor driver is a TB6560 (not great, but works
fine for my tinkering)."
After advising the chap to edit the ini file and set the step timing
where he needed for his drives.
"Ok, I finally have 3 axis working smoothly. Editing the ini file and
playing with the step and hold times did the trick.
My apologies for being a little cranky, but I was working on it all last
week and into the weekend and was just hitting the brick wall. I had
assumed that the PncConf was showing the true max limits (step/hold) of
the card, so I didn't think there was anything else to be done."
Thanks

Re: [Emc-developers] [Emc-users] Code of Conduct
Sorry to jump in again on the topic, that's exactly the why a CoC is necessary: it lets the community state what is the expected behavior, and the procedures to follow in case there is a violation. Obviously toxic behavior shouln't be admitted, even Alec's comment is contemptuous to Kirk. Human interaction can open unexpected Pandora's boxes, which put the community at risk. Avoiding this risk is the whole purpose of CoCs existence in first place, thus if we care about the project long term well-being we should welcome the institution of a CoC. I said I would not write for long time, but I have to heart this project and I feel that this issue must be resolved in a quite radical way, purifying the project's social places and development places from toxicism, so that people finds a welcoming project and is enticed to stay and contribute.
