Thanks Brett/Hood. I am getting closer. I did not select/attach the respective MPG's to the respective axes in the 'TAB' screen, so that is why the MPG's were not driving the required axis. That is all OK now. However, the MPG calibration is not working yet, probably because I do not understand the mechanism properly. I did as follows:
OPen CAL MPG screen
Select MPG-1
select CAL DETENT, and rotate encoder one detent - gives a count of 10 to 12
select CAL MAX SPEED, and rotate encoder quickly - gives a count of around 500 plus
select CAL STEP/VEL TRANS , and rotate encoder from slow accelerating to very fast, - gives a count of around 500 plus
select CALCULATE, says step done, then SAVE.
Then Select MPG-2 and repeat, Step done, then SAVE.
Now when I select MPG-3, the select button shows a 'dot' in it, but when I select CAL DETENT, or any of the cal buttons, the MPG-3 button is deselected, and MPG-2
becomes the selected encoder. I seem not to be able to cal MPG-3. However, when in ports n pins I set the Counts/Unit and Velocity values to be the same for MPG-3 as for the pre-calibrated MPG-1 and 2, then MPG-3 drives the axis in the same manner, speed, velocity, etc, as MPG-1 and 2.
So, in essence, it all works, except Cal is a little confusing.
Finally, the step size that each axis moves is 0.005mm ( I work in metric) and I seem unable to change this, regardless of the cycle jog step setting in the TAB screen. Maybe this setting only works for the HOTKEY jog modes? That does seem to step at the selected jog step size setting. I also do not see any change in axis movement step size when speeding up the MPG rotational speed - ie, velocity/step size is still a little confusing for me, and I have not been able to gleen much from the manual.
Kind of you all to help!
