I have loaded the Raindancer firmware on my mower, and I'm getting my first weekend days using it for cutting.
I'm having persistent issues with it turning off the mow motor.
Eventually, the ArduMower stops with an "ERROR: Motor M fault" message. (usually while cutting some taller grass...but not too tall...only like 4 inches)
I've read in the Raindancer wiki page that I'm supposed to disconnect M1OUT1/M1OUT2 so that the sensor is able to better read the consumed amps of the motor
I have bent disconnected the M1OUT1/M1OUT2 pins, and though the `mot.curm` measurement appears to have much higher watt values now....this isn't stopping the "ERROR: Motor M fault" message from occurring frequently.
I've found a good reference sheet. But I haven't been able to figure out much.
Questions:
- Is the "Motor M fault" caused by the M33926 latching LOW the SF output for either of the 2 outputs? (I think that is true, based on the schematic)
- What configuration and/or hardware changes can I make to stop the system from having "Motor M fault" ? Should I slow down the motor max speed, or the speed of the drive wheels? or something else?
- Does the mowing motor need to use both channels of the M33926? Why not only using 1 of the 2?
- How should I go about measuring the Amp draw of the mower? Clamping my Ammeter over the positive wire doesn't seem to do much (I don't get much difference in readings when the motor is idle, vs under load). Should I compare this with
Any advice about what to do here would be greatly appreciated.
Thank you
