Hi Ralph.
If phill?s Electronic Step Indexer is anything like mine then;
For example if I want 16 complete divisions for 1 revolution? = 22.5 degrees, then I select on the LCD screen menu "divisions" and not "angular".
In angular mode I can only get full degrees and not anything that needs splitting a whole degree number into minutes and seconds.
For 15 equally spaced divisions/segments, then I have a choice of settings by either selecting 15 divisions or 24 deg angular motions.
?Indexers are not really the same as the standard rotary tables, where you can use the graduated dials for splitting the degrees further to minutes and seconds,?
but are similar to rotary tables fitted with indexing plates ( meat mincers). Again normally we are talking divisions/segments when fitting these to a rotary table.
But there are?a few odd ball divisions/segments, one being 77 that sticks in my mind, that?cannot be achieved with the standard indexing plates,
You buy or make normally? 3 different plates in a complete set, ranging from 21 holes to 59 ?, I could be wrong. Long time since I used them.
Most standard machine rotary tables are either 72:1 or 90:1 ratios, but with the ESI firmware it?s possible to set these ratios and?
have them available on the LCD screen, if you were to drive a rotary table connected by a belt to the stepper motor
Please see the photo worth a thousand words. Stepper pulley 40T, rotary table pulley 40 T, ratio set on the ESI? 90:1 same as the 6" rotary table.
Most ESI also have a continual run mode and jog, this is useful for setting up parts.
Hope of interest.
