Hi! Im having some really weird issues with a Pixhawk4 board (Output to M1 isn’t working), I would appreciate any help:
Wiring (FMU-PWM-OUT → FMU-PWM-IN, IO-PWM-OUT → IO-PWM-IN)
Pixhawk 4 w/ px4 (tried with Ardupilot as well)
Pmo7 pwr management board
Airframe type (quad delta Vtol)
Hooked up motors M1 - M4 to ESCs with motors (swapped ESCs around they are all functional)
Outputs M2-M4 work fine but M1 can’t seem to connect to the esc (constant beeping)
Trouble Shooting steps:
- Reinstalled airframe reference / swapped to other airframes (any referenece with motors port 2-8 work fine, just port 1 doesnt)
- Reinstalled px4, tried different versions, tried Ardupilot as well
-Replaced PMO7 pwr management board twice (had spares) same issue
My Thoughts
If there isn’t an obvious solution I think that port might be dead (Which ever IO output from the Pixhawk 4 that maps to M1 on the PMO7). Sadly I can’t currently afford a replacement Pixhawk 4, so how would I go about editing the airframe reference to swap M1 to M5 (or any of the others).
