Re: Roboclaw - encoder readings are inconsistent based on direction of movement

Most linear actuators use linear pots as encoders. If that is the case I would say there is something wrong with your wiring possibly or the linear pot is bad. Sanity check the measurements with a oscope. If it is using quadrature encoders then the signals are most likely bad. Some quadrature encode...

Re: Using 3 roboclaw, packet serial, USB

The motor current and the battery current are related by the current duty percentage. Motion Studio(if you are still using Ion Studio, update please) is reading the motor current. If the motor is pulling 5amps and the duty us 50% then the battery is sourcing 2.5amps. When the Roboclaw sees current g...

Re: terrible spikes with PWM mode

They look like that because you have too much inductance in your ground lead. To get a clean look at inductive spikes you need to use the ground loop at the tip of the probe and keep the physical distance between the measurement points close together. The ground lead on most probes are fine for slow...

Re: broken the third MCP236 after few turns

The only way you can be damaging the current sense circuit is if you are producing a large negative voltage. That shouldn't be possible EITHER. Since there are clamping diodes on the motor channel lines. So only a negative spike on your power supply could cause the damage you are describing has happ...

Re: Feature Request: Studio app for Linux

I understand the desire, but this isn't likely to happen and I dont want to give false hopes.

Re: Using Current Sensing for Roller Shutter Endstop

With a microcontroller(like an arduino) you could potetnially setup somethign like that. You would need to run slowly when doing this "homing" from current readings to be safe. As for using a limit switch, you misunderstand it a little. It will move for UP TO 3 seconds(before timing out) to get out ...

Re: Both roboclaws sudenly stop

All of them stopping at the same time seems to be pointing to an E-Stop problem. Disable the E-Stop inputs on all the Roboclaws and see if the problem goes away. If it does you have narrowed down the cause. If it doesn't, then the next step would be to look at your coding on the Jetson. You will nee...

Re: Cannot see any Encoder values in Basic Micro software

How have you wired up your encoders? Have you checked the output from your encoders on an oscilloscope? Some encoders require external pullup resistors(usually to 5v) to operate properly.

Re: Getting parameters from roboclaw onto Arduino

We have an Arduino library you can use to communicate with the Roboclaw. Your question is way to general to be answered directly. We cant possibly write your code for you. You will need at least some experience writing programs on an Arduino.
