i know i've mentioned in a few other posts my servo issues. but with having gotten a new servo and having a new issue felt it deserved its own post.
so the problem i'm having is when going into the TOOLS/MORE on the printer. pressing the 2 and 3 actuates the servo. pressing 1 does not actuate the servo at all. since the servo does take the command to put it in the install position, position 3. it would stand to reason that it will accept a command to put it into position 1. my guess is, it is not receiving said command to put it into position 1. any help troubleshooting this would be great.
when pressing 1 or 2 the z offset adjusting does happen just not the actuating of the servo when 1 is pressed

What is the tip to fine tune the servo. I'm having similar problems3
i followed the instructions given by Makertech above about changing the degree in the firmware and everything is working properly now. sorry for the late reply
To give you some insight, position 1 is 0 degrees, position 2 is 100 degrees and position 3 is 45 degrees.
You can manually move the servo in pronterface:

<index> is 3, <pos> is the desired angle.
Something worth trying would be to set the hotend 0 degree position to 1 degree in the firmware under the SWITCHING_NOZZLE feature in configuration.h.
Further tuning of the servo angles will also help as outlined by another use:

still hoping for some kind of help here. i've sent a replacement parts form for the servo that died. but i suspect it will have the same issue.
