Re: Firmware 4.1.34: Power Cycle required when enabling Limit/Homing Switches

email support@basicmicro.com. Please include screen shots of all your settings, a description of the motors and encoders being used. Any more details you think important from this thread. I will have to setup a similar system so please be detailed. Most likely I will not be able to test this until t...

Re: [python2] Roboclaw instance has no attribute '_port'

This indicates opening the virtual comport failed. Make sure you used the proper name of the comport. Windows and Linux use completely different naming conventions.

Re: Cannot get Encoder value using ReadEnc command

1. You need your encoders to work correctly before anything else.
2. No, this is not normal. You should be able to manually move the motors extremely slowly and STILL get clean encoder readings. My guess is you need to add 5v pullups to the encoder lines on your motors.

Re: velocity autotune not updating PID values and crashing if retrying

If the autotuner fails it will not update the PID values. The autotuner first moves back and forth slowly. This is to get an approximate QPPS. Then it will oscillate back and forth fast. When this second stage does not happen(or appears not to happen) it usually indicates an encoder problem. What is...

Re: Stop Motion Command

That is clearer. Thank you. The default accel commands are documented in the manual. The default speed commands were just added and havent been updated in the manual yet. The command numbers are: SETM1DEFAULTSPEED 70 SETM2DEFAULTSPEED 71 Send: addr, cmd, speed (2bytes), CRC16(2 bytes). Receive: 0xFF

Re: broken the third MCP236 after few turns

The part you have marked is the opamp for the current sense circuit. It is unclear how you could be damaging that part. Unless there is damage else where(eg the HV regulator and/or 5v regulator, which powers the opamp. Does the unit still power up at all? How are you powering the MCP? What voltage? ...

Re: Issue: Not receiving encoder updates after calling SpeedAccelDeccelPosition function in Arduino Library

For other customers information: After talking with the customer for a while he determined the problem was limited to using the roboclaw.SpeedAccelDeccelPositionM1M2 command. Using roboclaw.SpeedAccelDeccelPositionM1 and roboclaw.SpeedAccelDeccelPositionM2 in sequence worked as expected. Also, this ...

Re: terrible spikes with PWM mode

The scope shots you show show the noise generated by the PWM rising and falling edges. Can you show scope shots of the 15s and 200ms spikes you talk about?

If I understand you, all you did was set Duty to 50 in motion studio?

Re: Configuration

All Roboclaw have the current blanking setting. They all use the same firmware with modifications for current limits. Make sure after you set it you click Write Settings under the Device menu. Failing with a false over current would stop the motors. If you motors continue running in autotuning it is...
