SlushEngine continuously shorts out


#1

I have performed only the initial test of m.move().
Initially, the robot moved however extremely fast. Then the board began not receiving power. After awhile, it worked again.

There is a perfect 24VDC going in and I don’t know where to troubleshoot from here (hoping that it will begin receiving power again in the near future). What are some good troubleshooting checks?


#2

Actually, This Roboteurs power supply might be the problem. I’ve noticed it losing power itself. Only when connected to the SlushEngine, however. So apparently there is a manufacturer’s short I need to find…


#3

Any troubleshooting tools built into the software that I could use?


#4

I’m off to purchase a 24 V power supply since it seems to be causing the problems; bad connections it makes (and a 12V for my relay board)


#5

Yep. It seems to be the SlushEngine that is faulted. Jiggling the power will give a momentary surge to the board while tripping the 24DCV power adaptor. I don’t know where to go from here. Buy another board and hope it doesn’t short exactly the same way?


#6

I’m buying a new board. I used this site: 1. A SlushEngine: any model will do, the code is the same. Buy One .
Despite the line saying “any model will do” I probably killed my board in true me fashion.
Any ideas on how to test components so I can fix it while the other one ships in?

HI Stephen,

The only suggestion that I have, is to make sure that there are no dry solder joints on the board, and ensure the components are seated and soldered correctly.

Also, try reducing the current of each stepper motor - I’m not sure what values you are passing to method setCurrent. You may be triggering either over current or stall current.
