Hi, I’m new to APM so apologies if I’m being dense.
Can’t get past the pre-arm checking. I have a freshly flashed APM 2.5 with v3.1.1 on my X quad. I ran through all of the mandatory setup but getting a “PreArm: INS not healthy” message when trying to arm.
I suspect the problem to be the compass or calibration of the compass. I’ve selected “APM with onboard, compass” and I’ve re-calibrated several times. Each time I end up with about the same values each time of x: -228, y: -70, z: -111.
I’m using a 15m usb cable so I don’t think the proximity to my laptop is an issue, but the x value seems extreme compared to the wiki which says it should be within +/- 150. I watched the youtube video and I’m following it pretty closely.
