RE: [CAD_CAM_EDM_DRO] Feb 25

EMC now is handling steppers as if they were servos from what I understand
(this may only be with the freqmot setup & the DRO setup?) and using freqmot
I can confirm that P,I, and D definitely have an effect on steppers. If I
set P too low I get constant follow errors at any speed, If I set D to
anything but 0 I start having a problem with the motors stalling on
acceleration (probably because this setting is trying to make the motor get
up to speed faster than the stepper can accelerate). I have played with
various I settings between 1 and 1000 and it does seem to help me get even
higher feed rates, but I have not really figured a way to see what works
best on this one.

You can easily play with these settings by going to the settings menu and
selecting calibration. The values will be for the axis that is currently
selected and will take effect as soon as the calibration window is closed.
Make sure you remember or write down the setting you settle on as the values
you put in the calibration window are not saved back to your .ini file, you
have to edit them in manually.
