Chain wrapped while calibrating. Something popped off the motor controller shield


#1

Are these not soldered on? Can I just reattach it with some thermal paste?


#2

I fear not :frowning:
Even if you could solder it back, I fear that the chip over heated and went to Nirvana.


#3

So are these soldered on or not?


#4

Yes, they are soldered.


#5

And I can’t find any replacement shields in stock. Am I going to have to just completely scrap the entire thing?


#6

You could buy a replacement chip from digikey or arrow and solder a new chip on.
Where are you located?
Maybe contact the 3 new suppliers directly.


#7

I’m in north Louisiana. My soldering skills are extremely basic.

What 3 suppliers are those?


#8

@Metalmaslow, @2cents and @MakerMadeCNC


#9

SMD parts are also not for me. I did order chips for the 3 shields i’ve burnt in the past, but never attempted to solder them. The TLE5206 shield in thruhole version is what i run now. Can take more abuse then the original shield, so i would name it the successor.


#10

Is this the 1.4 shield sold by eastbaysource? Those are also sold out.


#11

Yes, sold out.
Also Bee has stopped selling this one:

#12

I’ve got some 1.2 boards available if you want a replacement.


#13

I’ve already ordered one, but thanks anyway.


#14

LOL. It is frustrating, but I couldn’t help but laugh.

I could totally see this happening to me.

A little duct tape, and you’re back in the game.


#15

I’ll try that tomorrow.


#16

I assume this is a joke?
If the chip unsoldered it self, I would not trust it any more. It has likely shorted.


#17

It did eventually occur to me that duct tape probably wouldn’t be best for this particular situation.

I managed to get a new TLE5206 shield ordered from eastbaysource, so I’ll hopefully get that Wednesday.


#18

Great to read, keep a good eye on your chains :wink:


#19

I’ve seen thelist of improvements to the new board, but how exactly does the new board improve on the actual performance of the machine?

Also, are there any changes or adjustments I need to make in Ground Control when I switch out the boards?


#20

It should be plug and play. GC will report the board as 1.3 if all goes well and you do not need to do anything.
The board has 2-3 improvements:

  • each motor has its own chip
  • the chips can take more AMPs (careful if you use the ‘pull chain teight’ for motor distancemeasurement. If your frame or motor-mounts are weak, you will notice with this board, because for the first time you will see 30kg pulling for 3 sec.)
  • not sure about your board, but with bees’ version you can bring more pins up, to use for example to control spindle speed or a relay to turn the router on/off.

I found a picture in the archives of a tested but not recommended solution against chain-wrap :wink:

We did not have the countdown then and i had to run.
