Re: [CAD_CAM_EDM_DRO] Re: New on EMC: How to set the steps per unit for each axis? for metric

Hi Frank,

For metric units to work you need to change the Linear value to 1 - it works
on my system without any trailing zeros. Also the INPUT_SCALE should be set
to the right number of steps per millimetre and the OUTPUT_SCALE to 1/10th
of this number - so, if your stepper does 1000 steps per millimetre,
OUTPUT_SCALE needs to be 100 to make the system display correctly.
As for the system crashing, have you commented out the PERIOD parameter -
put a ; in front of it - and, the MAX_ERROR and F(ollowing)_ERROR values
will need increasing by at least 10 times.
HTH
