Re: Packet Serial Mode Latency Issues
You need to determine if you are getting failed packets. If a packet fails it takes a minimum of 10ms to clear. The Roboclaw python library is setup to retry several times so failed packets add up to significant delays. Note: they are not the problem. They are a symptom of a problem. If bad packets ...

Re: Problems with 2x7A
1. I recommend you not try using AA batteries to power your robot. They will droop massively in most cases and cause you massive headaches trying to figure out the problem. 2. Just because you wired up encoders doesnt mean you can use them. You need to tune the PID settings to use them. But first yo...

Re: One motor slowing down (stopping)
Current blanking window sets the lowest duty percentage current readings will be used. As the duty goes down the PWM width goes down. Depending on the motors the rising and falling edge of each PWM will have noise. We take our readings between these edges but as the duty goes down they get closer to...

Re: Reset Roboclaw with buttons only
You can reset to factory defaults by holding he middle button while turning on the unit. However error 2 is a driver fault. That is usually a sign of physical damage. If the board was wired wrong that is how it was damaged. If the problem goes away after fixing the wiring you got really lucky. I wil...

Re: Calculating size of pre-charge resistor
118 ohms is reasonable. 1/4 watt is more than sufficient. 1/10watt would probably work in most cases as well.

Re: False Overcurrent Warning
You just need to adjust the current blanking % for that motor channel. The default 5.4 is fine for most small motors but if you are seeing false current readings it is because the window is too small(noise at low duty cycles cause the false readings and the window setting prevents those current read...

Re: basic micro freezes during tune
During autotuning we do understand the program can freeze. This is usually caused by the PCs USB port crashing. This can happen due to noise from the tuning. You can mitigate this by using a USB cable with a ferrite choke or use a USB isolation adapter. Even with those it can happen sometimes. It de...

Re: Motors getting hot while robot immobile
When you know you are stopped you can remove power from the motors all together by sending a 0 duty command to each. This will stop the velocity PID from controlling the motors and fighting each other if your suspicion is correct. I expect it is.
