Faulty Toolboard 1LC V1.1?

tecno

@martinnyhc

Check all connections to/from 1LC

MartinNYHC

Did that several times. I'm debugging since the morning when I simply replaced the toolboard.

There are only two, power and CAN bus. That's the reason why I'm using it

@martinnyhc
Also using V1, had this problem = bad connection on CAN or the thermistor.

@martinnyhc if you send M308 S1 what response do you get?

Have you tried using the temp0 connector on the tool board instead of temp1?

@martinnyhc if you disconnect the thermistor from the tool board, do you still get the "bad VSSA" response to that command?

MartinNYHC

Yes, it's the same result.

And yes, I already tried temp1. I tried everything I could think of Tried to isolate the problem but unfortunately without success. Lucky me, that I have so many spare parts except a toolboard.

@martinnyhc the "bad VSSA" error even with no thermistors connected suggests a faulty tool board. Please send an email to warranty@duet3d.com.

MartinNYHC

Will do so. Thanks for our support.

@martinnyhc

Looking at the picture there is no CAN terminator or is there?

terminator

It is, but on the back

@martinnyhc

OK, just checking

No problem, I'm sorry for the inconvenience.

Note to warranty processing: check F1 R32 R36 R47

Sorry, but what does that mean?

@martinnyhc Just @dc42 letting us know things that should be tested on the board. Please email warranty@duet3d.com. with this thread and we will take it from there.

That was for us, so that whoever checks your board knows what to look at.

However, there is a possibility that we may not need to replace your board. We made a change to the version 1.1 board that affects the Vssa reading a little, and I forgot to adjust the firmware accordingly. So your board might be close to the tolerance limit, allowing it to pass our test procedure but fail in your environment.

Do you have a multimeter? if so, then with power off, please measure the resistance of the green polyfuse on the board. It should be just a few ohms.

MartinNYHC

@dc42 It measures 0.9 ohms.

@martinnyhc, please can you install just the tool board firmware (not the other binaries) from https://www.dropbox.com/sh/ja08b7qdzsl8kjc/AAAwUbkN2XJvurq5CuQTgx5Wa?dl=0 and then get a M122 report from that board. I've added extra diagnostics so that I can tell whether it is a tolerance issue or a fault.

@martinnyhc thanks, from your M122 report I can see that your tool board is definitely faulty. Looks like either the green PTC fuse isn't properly soldered, or resistor R47 next to it isn't properly soldered. Warranty replacement.
