Encoder not found with dimmed light on mother board

first build.

Finally set up my Maslow 4 no frame as of yet just getting through this part first.

*turn machine on
*log onto webpage
*hit ALARM
*go to setup
*hit retract all as directed in setup manual…
*dialog in code box says [MSG:INFO: Retracting all belts]
*
*
*nothing happens.
*check all connections
*try again
*
*Nothing
*be me see word test in setup.
*hit test
*Code box.

  • Problem found [MSG:ERR: Encoder not found on Top Right]
    *Check forum find someone else talking about similar issue. Dam not same issue.

*Diagnosis time
*Issue - lights are on but weak barely lit. on both encoder board ethernet port and also on main board.
*
*Problem solving.
*Swapped ethernet cord from encoder front right to front left and the left to the right.
*front right encoder is now plugged into the front left motherboard
*front Left encoder is now plugged into the front right motherboard.
*front right encoder passes test disguised as front left
*Front left encoder light now dim and top right mother board is still dim, failed again
*
*Conclusion
*Encoders are fine
*some thing wrong with mother board.
*Tried update all files
*have turned on and off again.

hopefully these pictures help

the lights cycle through brightness as the encoders move, bright or dim does not indicate a problem.

once the test works (with everything plugged in correctly), then you can hit retract-all

don’t forget to click on the alarm to turn it off, otherwise nothing can move.

IT fails test and will not retract.
The encoder that it is failing on has a dimmed light as shown in picture no movement necessary to change lighting.

And as these lights are a network port I imagine the lights aren’t dimmable and in fact are on off led and would indicate connection or data transfer and dull light would indicate voltage issue and as it is present on both encoder and board port, but only on the encoder it’s connected too on the front right Chanel port it would suggest motherboard issue.Because it doesn’t matter which encoder I change it to that encoder now has the dimmed light.

you are misunderstanding the lights, any LED is dimmable, it just gets turned on
and off at different rates.

they are not indicating data transfer, and it’s not actually a network port
(just a convienient cable and connector format to use)

when you say it fails the test, is it reporting encoder failures or motor
failures? is one encoder always failing, or is it one port even if you switch
cables/encoders around.

The yellow light being dim is normal, the yellow lights on the encoder will get brighter and dimmer as the encoder rotates (and be off entirely at some point too). The green light one the encoder board and controller board should always be on and always be full brightness.

So the takeaway is that any encoder which is plugged into the top right port will not pass the test?

Same port failure. From the board encoder doesn’t matter always top right port on main board.

Correct no yellow light as demonstrated in pic green light barely lit.

forget the lights, what does the test say? does it always say that the same
encoder has failed, no matter which encoder/cable is used?

That is as stated in the initial post.
