How to configure Delta with 4 arms?

[KCMARINE]

@zapta Thanks,

Yes agreed we are on the right track - this config is adding a 4th tower to carry a flying extruder which is an excellent feature.

Further to this investigation, we would like to figure out what commands are required in the config file to combine the (4th Tower and Arm) - to the - (End Effector with the Hotend)

@dc42 can you share any thoughts on the direction of this investigation please would be greatly appreciated. Cheers

You don't want to add another tower, but the angles of the three delta towers are also different: 90° instead of 120°.
How do you setup for this?

This is an amazing video showing the operation.

Great work by them and I can only hope to work towards something like this for RRF

Let me know what you guys think?

@kcmarine set up for 4 towers as if you were adding a powered flying extruder as described.in the documentation. In the M665 command use the XYZ parameters to specify that the first 3 towers are at intervals of 90deg instead of 120deg. Then use the M669 X and Y parameters to specify the position of the 4th tower.
