  As long as the M-Motor is spining free, the SBricks PWM-signal looks totally OK.
  
   
  But when I use my fingers to stop the M-Motor, the signal turns into this:
  
  You can see that when the motor is blocked, the SBrick for some strange reason no longer delivers a correct PWM signal. I most cases I could even stop blocking the motor with my finger but it did not spin up with this PWM signal applied.
  The two pictures above have been taken with used batteries (around 7,5V). However, the situation is the same with new batteries or even when I connect a power supply.
  Furthermore, if I connect two M-Motors to the same port, they do not work at all. They make some noise, but they do not start rotating. (but 2 M-Motors on to different ports work)  less

  SBrick Plus: Full Speed or No Movement

  Hi,
  I bought a new SBrick Plus few days ago and used it for the 42065 RC Tracked Racer. I created a simple profile with 2 sliders. However the Racer does not move at all until I push the Sliders to +100% or -100%.

  I bought a new SBrick Plus few days ago and used it for the 42065 RC Tracked Racer. I created a simple profile with 2 sliders. However the Racer does not move at all until I push the Sliders to +100% or -100%.
  I could reproduce this behaviour with a sequence:When setting the output to 0.95, the racer makes some noise but does not move at all. When I set the output to  1.00, the racer moves (very fast, same speed as with the Lego IR).
  I already tried to upgrade the firmware (23) but this did not help at all. Is this something like a known problem with the SBRICK PLUS? Is there any work around? I found this youtube video in which the race is able to drive slower, so it seams to be no general limitation of the SBRICK.  less
