Greetings, RICH.
I have made everything that you have told.
Has updated масн3 to last version. Has made a disk with one crack (diam 140mm, length 9мм)
Now the following has turned out:
When I twist a spindle a hand, approximately 2 turns in second, an index signal blink and speed of 90-110 turns in a minute is shown. Truly.
When I include a spindle on low speed, approximately 2-3 turns in a second, the index bulb blinks non-uniformly, speed of 200-2000 turns is displayed minute....
In what there can be a problem?
Thanks.
