Is it possible your motor/encoder moves after being stopped, and it then goes into the speedAccel path again? If not, is it possible that the current sensing calibration is off, and it just reports 0.06A even when it's at zero? If you put an amp meter in line with the motor (assuming you have one th...

So, this seems to be a work-around: void setvoltage(uint8_t id) { unsigned char cmd[] = { id, 57, 0x00, 0x28, 0x01, 0x00 }; wr_claw(cmd, 6); } It sets the main battery range to 4.0V .. 25.6V, and then the claw doesn't complain. If I can know which components specifically measure the main battery vol...

The data you asked for:
They are all running 4.1.17.
The problematic board reports 0x800 (main battery low) warnings when it complains.

... I will try setting the main battery voltage levels to something really low/high and see what it does.

Also, I cranked the oscilloscope up to 100 us/100 mV per division and probed straight on the power capacitor on the board, and filmed it. It doesn't really show anything more than what I suggested already, but here it is for what it's worth: https://photos.app.goo.gl/aNifp8A1uO2359GI3 You will note ...

Yes, I'm using packet serial. I'll read the status back and let you know tonight. The firmware is the same one that got installed when you had the boards last year (I read it back and verified when I opened the bag, but don't remember off-hand); I think version 4.17? I'll verify that tonight too. I ...

Disconnecting all wiring except power, this controller still blinks red when another controller is running. A scope on the power wire shows < 100 mV ripple. Isolating the controller from the chassis ground (resting on plastic, only connected with power) shows the same thing. Moving this controller t...

Last year, I was having some trouble with Roboclaw 2x5A controllers detecting "overcurrent" and disabling, even when the motors driven had a stall current less than 5A. The problem was traced down to something that required me to send the claws in. I sent in all three of my 2x5A, but time ...

That's pretty clever

If I want the wheels to free-wheel (H-bridges disconnected, no shorting/braking) what's the best command to send? I realize that the motors will work as generators when doing this, but I'm well within safety margins on voltages here. I will just be dragging the rover over ground to calibrate the dia...

Alright, I'll give that another go-around. Thanks for the advice! Another perhaps-relevant factor is that I'm not very aggressive in the acceleration I specify. (I'm a little more aggressive when decellerating.) I use QPPS/2 for acceleration and QPPS*2 for decelleration, but those values alone don't...
