Description
Swinging/switching CR10S hotends for the G2s delta printer
By using magnets to lock the position, servo jitter and inaccuracy is no issue
By using an eccentric drive it is possible to use a very small rc servo with 180°
Bearrings used to swing are MF63ZZ
Bearring for the eccentric drive is MR148ZZ
Magnets are Neodym 8x3mm with bore
Servo is a TowerPro MG90S
All fans are 30x30x10mm, two for hotend and one for layer cooling
Activating the servo subsystem in Marlin by setting nr of servos >0
At hotend swap send "M280 P0 S50" for hotend 1
or "M280 P0 S150" for hotend 2
On the GT2860 rev A board the servo pwm line has to be soldered to R22 (cpu side)
