Rotary delta calibration not implemented?

is it possible in the future to add support for spi or i2c external ram?

No.

or is it easier to buy a board with more memory?

Yes, such as the Duet 3 MB6HC or Duet 3 Mini.

Why doesn't the G30 work in any way? I can't properly measure multiple points(

Because the auto calibration code has to be written to suit the kinematics, even though the basic principle will be the same as for a linear delta. We may also need a more sophisticated way of configuring which parameters are to be calibrated, rather than just having a # of parameters as we do for linear delta.

My guess is that the homing switch positions and delta radius are the most important to calibrate. Do you agree?

"My guess is that the homing switch positions and delta radius are the most important to calibrate. Do you agree?" - Yes, you're right.

@dc42 you didn't do any "calibration"?

I don't have a rotary delta. I implemented the kinematics for a user who had one.

@dc42 And thank you for that.

@dc42 do you happen to know this user?

If you enter rotary delta in the search box for this forum, you will find his posts.

I will add calibration for rotary deltas to the firmware wishlist.
