S1 and S2 inputs can only be Packet serial OR RC mode, not both at once. If you are using an Arm based Arduino you may be able to setup a USB host and talk to the Roboclaw with USB packet serial which would leave S1 and S2 free for RC control. Otherwise, the answer to your question is no.

My suspicion is the roboclaw thinks it is somewhere other than where you think it is when you first start your program. You should always check the current position or home the motor before making your initial movement.

Yes a common ground is required between all roboclaws when you are using multiple units like that. The USB only supplies a ground between the PC and the first Roboclaw.

Based on your description I would start with a stronger pullup. You can go to 1k safely enough. However your power levels are low in general. 7amps is nothing. I suspect something else is going on. Put the scope on 5v and see what happens there. The internal pulldown(I assume you have inverted the p...

Each autotuner function measures QPPS and then runs the autotune function. You no longer need to enter tha QPPS values before starting. It will be overwritten. The Position Autotuner also run s a velocity autotune if you have it set to PIV which will overwrite your velocity tuned settings if you had...

If the Autotuner doesn't get the values it wants it will just keep trying which will cause the UI to freeze(technically it freezes the UI while autotuning always, but it happens fast enough no one notices). I/ve have made a note to address this in the next firmware update. On the other, can you reme...

Thank you.

We've come a long ways from rovers, that is for sure.

If your communications are intermittent you will be adding significant latencies retrying failed commands. You'll need to describe what happens when you try autotuning as well as describe your actuators hardware. The autotuner cant tune every setup. Especially low resolution ones or non-linear ones....

Roboclaws were originally designed for 4 wheel rovers. The labeling reflects that, eg battery operated. DC Motors act like generators when they slow down. period. All DC motors do this. Its not optional. Some motor controlers have built-in voltage clamping. Those motor controllers tend to cost an or...
