Hi, I am setting up a fifth stepper axis (B) to drive a lathe head on my little miller and have run into a minor problem. The new ini file is at http://tinyurl.com/yoahtm The axis is working OK and I am getting a reasonable turn of speed out of it for what I want to do but the feedrate I need to enter is ridiculous... I am driving a 200 step motor through an 1/8 microstep driver (Allegro) and the spindle is driven by a 3:1 reduction toothed belt drive. The ini file as it stands allows me to acurately position the spindle by degrees for such things as gear cutting and also turn it at a few hundred rpm for plain turning. However, at its top speed, AXIS reports its speed as 66000 and, to get it to move at that speed, that is the figure I have to enter as feedrate in a G1 move - cumbersome to say the least... So, is there any way I can introduce a divisor into this feedrate figure to get it down to a more sensible figure - it is unlikely I will ever want to turn the spindle at very slow speeds so a divisor of 100 or even 1000 would be great.
