When I printed a con model after six factor calibration, it printed the deformed con in rightside.
I found it the six factor cablibration introduced excessive angle variation of towers which deform geometry of any model.
To check the current delta configuration, run M665 in gcode console on DWC.
The calibration assumes all 12 ball joints are square and in parallel, three towers are perpendicular to the bed.
And it will create best delta configuration to compensate the deviation based on probe points.
I learned the critical steps that impact calibration later on are the assembly of ball joints in carriage and effector.
A pair of diagonal rods require parallelism:
- the width of two ball joints is within 0.25 mm both carriage and effector side.
- length variation of two diagonal rods is within 0.1 mm.
(It will unlikely happen because of the laser cut precision.)
