[SOLVED] X-RACER f303 + XM30A motors don't start
#1
Hi all Wink

I  building a new racer with XRACER F303 (v2.1) and ESC DYS XM30A, but i have this problems:
- Motors don't start
- ESC don't start calibration mode in cleanflight 
- Bheli don't found ESC type or name

After i have changed xracer by naze32 (rev5), everything works ! (motors start, esc calibration work, ESC flashing with bheli work)

I just received a new xracer (v3.1) but i have exactly same problems.

Wrong connexion ? incompatibility with xracer and xm30a ? SBUS problem ?
I don't found why, please help me.

My setup:
XRACER F303
DYS XM30A
EMAX RS 2205
Matek HUBOSD Eco H-Type
FRSKY X4R
FOXEER TM200


My dump can found here

I've got an F303 V3.0 on the way, and I haven't inspected it closely, but I don't think you can power the FC through VBat (That's the only connection of power I see in your diagram). I think you need to supply +5v to one of the Vin motor pins (or some other Vin). Someone correct me if I'm wrong.

Oops, sorry, see it now.

Thanks for your answer.
I know my diagram is not very clear. I power the FC by a BEC 5V of Matek connected to channel 8 on xracer v2.1 or channel 6 on v3.1.

Somebody said to me he have connected servo ESC to PW pins on xracer and not to CH pins like me. Maybe is that ?

FWIW, I had trouble with my flip32s when I ran too many grounds to the FC.  I ran grounds on my ESCs to the FC and then another ground with +5v to the FC.  I had similar problems.  I removed the ground (like motor 6 in your diagram) and everything worked.  Now when I wire my flips I don't use ground for VBat or for FC power.  Only grounds are from the ESCs.

You might try removing the VBat ground and see if there's a change (or not).  I do have the RealACC version of your PDB, but haven't installed it in anything yet.  I just know that's one place I'd look if I had the trouble you are having.

I didn't notice that before, but I think that's it.  The motors should be connected to the PWM pins, not Channel pins (from FPVmodels diagram anyway).

Solved !!

I just connected ESC servos to PW pins and not to CH pins and everything work well !
I am so stupid...

Thanks a lot

Not stupid - easy to do stuff like that, and sometimes it's hard to spot.
