Hi Gregg .
The locking of the steps is fine in case of safety.
The X-Y axis have always to complete the stitch lenght movement, otherwhise
you obtain a non costant stitch lenght.
Hi Michal
Thanks for the infos.
A couple of questions more.
How do you synchronize the needle movement with the X-Y

i'm having a problem trying to get a analog 10v spinde to scale correctly
the spindle has a 1000 count encoder
and gives a speed of 6200 rpm
now either i set the scale at 62
and i get movement or what i thought was correct and get full speed and no
change
as i calculate if i am correct

Thats good info but does go far enough. Does it do A/B/Z

this is with a 5i25 and 7i77 analog card ,

The 7i77 card will read that with no problems. In fact it can go a whole
lot faster.

If you are using a 2048 pulse per rev quadrature encoder in counter mode
then only the A channel pulses will be counted. Both edges are counted
so you get 4096 pulses per revolution. And I think it should be scaled
to revolutions per second. Not sure of this though.

OUTPUT_SCALE = 0.00161
Is that value actually used anywhere in the HAL?

If you can't fix it, you don't own it.

It is supposed to be used for feedback scale, I think. Most people just
hard code that in the hal file

None of the examples there reference the INI at all, so changing the
number in the INI wouldn't have

Thank you so much for the very detailed informations .
You are considering to move the needle as a spindle with the S parameter to

This sort of thing should be fast and accurate enough for moving the
sewing machine platform in between stitches.
