I’m new guy for electronic part and not read instruction carefully. I already built Hexy but I forgot to calibrate the servos. Any suggestion ? Thanks
If by calibrate you mean centre, then this is the part of the build guide you missed
"With batteries plugged into the servo plug on the controller, any servos plugged into ports
0,1,2 or 3 should automatically center (you will hear some brief whirring). If they don’t, the
firmware is probably out of date and may require an update.
Plug a servo into slots 0,1,2 or 3 in the controller. Make sure the brown wire is in the
prong closest to the controller’s edge."
What you’ll probably see is a lot of different directions for your servos, since you forgot to centre them during the build. Your best bet is probably to loosen the screws holding the servos in place and take them out of the horns, centre them, then tighten everything back up. If you don’t feel like that you might be able to get away with some incredibly large offsets in PoMoCo.
Hope I haven’t misunderstood your question
Thanks for your quick answer Deadpoodle.

I have another question. If I should use offsets in PoMoCo, What’s effect to Hexy ? Can It work normally?
The offsets are there for the specific reason of making him walk normally. You might notice that even though youve centred the servos during the build, some are pointing off-centre, using the offsets you can make them all line up the way they should.
You should definitely centre them as best you can then use offsets to make sure they’re all lined up 100% correctly before you send him walking or anything else
If you have large offsets in PoMoCo, you’ll have a limited range of movement in your servos. As the servos can physically move about +/- 90 degrees from centre, if you have to put a 40 degree offset in the software, you’ll restrict your movement in one direction by about 40 degrees. Best to loosen the horns and do an approximate physical alignment before you start putting large offsets into PoMoCo.

I wanted to test out the servos before assembling Hexy, so was just working off the board and had only skimmed the build guide. Nothing worked, not even a different servo I had around (from another Arduino kit) which I knew worked. Turns out that

Thank you everyone. I center all servo and reassembly.
