End effecter servo is off-center on firmware 4.2.0

uArm Serial No.: (the No. at the bottom of each uArm reading “UARM-XXXXXXXXXX”)

Firmware Version: 4.2.0

Operation System: Win 10

uArm Controlling Method: uArm Studio 1.1.17

I updated my uArm to firmware 4.2.0 which is supposed to make motion a lot smoother. Immediately after updating the firmware the end effecter/wrist servo is offset. In uArm Studio I have to set the angle to 107 for the servo to be centered again. This was not a problem in the previous firmware. I think there is a problem with the firmware and not the servo itself.

Hi, thanks for the feedback, we believe this issue is caused by the error of the 4th servo motor instead of the firmware.

I did not see this issue with the current official firmware that comes installed by default. An error of 17 degrees seems really big no?
