steps/mm in config for seesaw configuration

[Sahiru Hettiarachchi]

Hi

How do you determine the steps/mm in a seesaw,rocker configuration?

Thanks

Factually, its not steps/mm but steps per degree you need to set. Make it so 1 rotation = 360 units. OpenPnP will then transform the wanted Z mm to cam degrees (sinus function).

Some controllers (TinyG) have actual rotation/degree units, others just handle degrees as "mm" (it does not really matter in the end).

Thank you Mark,

Then I can consider the rotational axes too like this and think about degrees as mm can I?

Yes.
