Hi all;
Just for the email record in case others come by and google:
The Sieg KX1 mill I have has on X/Y axis YK57HB76-03A and on the Z
axis YK60HB86-04A
steppers.
This mill is sold by ArcEuroTrade, and LittleMachineShop (pn# 3501), plus
others, I'd guess. Mine came as a "KX1-NU" from Novakon o
Hi Kirk;
Can you get single steps to move the motor? I would try ...
All interesting suggestions. I did wish that the G540 could have
microstepping disabled, but does not seem possible.
It would appear (more stress testing today) that the issue was that I was
close to the speed limit on the op

I have two G540 units. One of them refuses to step on the Y channel when
the step rate is below 110Hz. If the step rate is slowly lowered the
stepping stops very cleanly at 110 Hz. This is not affected by step
pulse length.
I communicated with Geckdrive about this and it was a suspected fault i

It's probably better if I don't try to second guess what may be of

I would also try inverting the step pin. It isn't clear to me if the
drive uses positive or negative logic. My drives are opto-input and
definitely use negative logic.

Ok, so bumping up current to 3A from 2.2A this morning did not change
anything.
The power supply is a 48v switcher from Keiling; I'm thinking of removing
all other axes and just testing one axis, and/or find another power supply
to see if it might be the issue.
Two questions, for those who are br
Two interesting suggestions to check - two that I would not have thought
of.
We'll see what happens today - I should have a good few hours to work on it.
Thanks - JohnS.

Absolutely. Going very slowly is what steppers are best at.
I wonder if something is (Accidentally) AC-coupled somewhere?

Have a look at the timing requirements for the G540. As far as I recall
it needs some longer pulses. You have to set the step pulse length as
well as some other settings. There is some wiki stuff about this.

I have a stepper based mill that I have reconfigured to use a Gecko G540.
Stepper motors rated 3A, with the G540 resistor setup, I'm using a 2.2k
resistor, giving 2.2A. Power supply is 43v. (48 v switcher, tuned down to
43v because that's the voltage the G540 docs say to use with the inductance
