Hi there,
I have Marlin 1.1.0-RC6 and a Rumba board.
I am trying to implement the ABL but the servo does not move.
I have connected the servo (SG90) on exp.3 pins:
2 (+5V)
4 (-)
and then I tested the servo on both pin 6 and 5 for the PWM
In Marlin I have activated the auto bed leveling options and the R/C servo support, in fact if I send a G29 the printer moves and does the mapping of the bed on 4 points. I have manually pressed the Z end stop to cause the routine to complete and return the mapping in Pronerface. I have also tested the same with RCBugFix downloaded a couple of days ago but same results.
I have tried to send the command manually to move the servo M280 P0 S90, I tried the same command on P1 and P2 on both pins 4 and 5, but nothing....I cannot move the servo. I have checked the servo functionality before and after the test on rumba with an Arduino board and the servo is functional.
I checked in pins_RUMBA.h and the servo 0 is assigned as #define SERVO0_PIN 5
I have checked the voltage on pins 2-4 of Exp. 3 and the voltage (5V) is there.
I have opened an
issue on Marlin GitHub but even there I am not coming right.
Please help.
