Gene,
The rewiring is indeed something of the past. I did just the same, had a
very simple breakout with rc filtering and switching the pins to comply
with the xylotex. But since the changed hal, there is no need anymore.
Ha. Hope the guy measured before using this cable!
I'm assuming there won'

Jon, Gene,

(the 4 axis) it is around 1.8V and for the old board approx 3V.
What bothers me the most is that I have the problem on both the old 3
axis and the more recent 4 axis board which I guess would rule out the
xylotex b

Guys,
I'm getting lost here:
- attached the old 3 axis xylotex: same problem
- hooked up the scope to watch the step signal: step high approx 3 us.
Should be ok as xylotex says 1000 ns minimal. 5 volts.
- at approx 1000 Hz pulses seem ok. a little twitchy on the scope screen.
- attached older
Jon and others,
Thanks for the replies.
The configs were in the ~/emc2/configs folder (home directory). So I
guess this is not the problem.
Playing around with the steplen and stepspace parameters does make the
pulses nicer, but steppers still behaving erratic. Although I'm quite
