Settings - roll angle setup offset value

It would be great to define a permanent roll angle offset in the settings.

Did calibration, don't know if my phone is wrong, but the horizontal line seems a little bit to slope down on the left, if fixing a horizontal line.

Htc one m7, without extra weight, 145g.

Would guess it's hard calculate camera position/ phone angle with soft grips and camera far away left.

Second possibility: software does use picture mode to calculate horizontal line angle offset and puts this value under settings.

When doing Calibration, try pressing from the top side, instead of pressing on bottom side, to ensure bottom side of the grip is lying completely flat on the table. See if this improves roll angle slanting issue for you.

Re: Settings - roll angle setup offset value

I have the same problem. My horizontal is sloping to the right (phone tilted to the left). I tried the Horizontal Level Adjustment tutorial at https://vimeo.com/187276331 but when I restart the gimbal, it goes back to the sloped horizontal.

Hi Tantung,

When doing level calibration, try press down using 3 fingers from the top, on both sides, https://vimeo.com/187616355 (1:46 ~ 3:15)

When mounting phone, also push phone upward a bit from the far end to avoid slanting, https://vimeo.com/187616355 (5:20 ~ 5:34)

Please see if this helps.

Re: Settings - roll angle setup offset value

For me it's not getting better.
Video instruction did in "follow pan" mode turning left and turning right change angle much more in different directions.
Tried different points to press the finger in. For example on the outer joint, then turning left and right 90° level was ok left and right but not straight on.
So, turning left and right also changes angle of phone by some degrees in "follow pan" mode. This is weird.
Looks like 6:15 here https://vimeo.com/187616355, but perhaps optical illusion.
Also after horizintal adjustment video! Have no time to make video now.

Please show somewhere in the settings the "gimbal Mac" and "xyz g +/- weight" settings. This would be helpful as an extra line.

Re: Settings - roll angle setup offset value

I have an android app called "Spirit Level" it uses phone sensors to show degrees and levels of the phone.

Suggestion: instead of calibrating and pressing fingers on the mounting grip it perhaps would be worth considerating to get the "level or degree data" via bluetooth directly from the phone... perhaps a bit work because of different phones... but perhaps easier than my previous suggestion, to use the camera and compare the angles in the picture with the roll angle settings.
