Hi,
I was just thinking about designing/printing a new effector for my delta, when I realised, that a different sized effector (for example a bigger one with longer magnet to magnet distance) will change my arm_radius.
Precisely measuring this new arm radius can be tricky, so I wondered, if this can be calculated by the smoothieware calibration routines (I have a bltouch sensor installed).
In the z probe delta calibration guide, there is a note that says: “this calibrates the endstops and delta radius only”.
But if you scroll down on that page to “configuration options” it says:
leveling-strategy.delta-calibration.enable true
Set to true to enable the delta calibration levelling strategy. This uses the probe to figure out the plane's tilt and arm's radius in a delta machine
So it this simply two different phrases describing the same thing?
I thought arm_radius and arm_length are the two crucial values, that should be put in manually and need to be correct as possible, so the calibration routine can change endstops+printer radius (or delta radius, as wording seems to change between firmwares) for getting the bed level as flat as poissble.
Can the arm_radius be calculated, or only be measured manually?
Best regards,
Benny
