re: CRAZY STUFF UPDATE

Hi all,

I guess I should drop this subject now. ( I am not doing much with

steppers anymore )
I just wanted to pass on a few ideas, that is all. But if anyone
would try this, here is a little note.

There has to be time enough to insert the extra steps, and there
is
many ways to do this, but I will just present what should be the
simplest thing to do. When the detecting circuit shows you lost a

step, and you should be so lucky that you are running in half-step

mode, just switch to full step during the next step. If the
detector still has not even out, this will repeat on the next
cycle.
If nothing serious is preventing the movement of the axis, it
should
be corrected in just a few steps. Remember: If you loose a
step,
the detector will notice it by the same time. That is, you have
just
lost one step at this time, so doing a full-step as the next one,

you should have corrected this. You also have a bit more torque,
which also will help.

In the case you run at full-step, then it depends on how fast the
step rate is at the current time. You need time enough to insert a

double step, or issue this a step when there is an open "window"
for
it.

Enough for now.
