E1 extruder not working on dual extruder A20M

Post by delir6 » Sat Apr 18, 2020 7:36 pm

Hi there.
I have A20M dual extruder (1 hotend). GT2560 v3.1 board. A4988 drivers.

The motor from E1 extruder stopped spinning while E0 extruder works perfect.
If I put motion on Extruder axis , the E0 will spin normally while this one will just try. You can feel it. The motor works ok.

I did the following testing:
-heated up PLA head
-tried E1 motor on E0 cable and working ok (motor works)
-tried E0 motor on E1 cable and not working (same as with its own motor)
-tested E1 cabling point to point.
-measured voltage in between the driver potentiometer and Ground on all Drivers and is between 1.03v and 1.1 volt on all of them.
-swapped drivers between E0 and E1 with no success. Same behaviour.

I don't think it's a firmware issue, since I never updated anything. It just stopped working.

Thanks. Any recomendation?

Yes, I did, I just can't go further.
I think might be a motherboard issue....

Thanks anyway. I will send a query to technical support.

Finally it was ME BAAAAD!
Somehow, after starting printing from the SD (before used usb cura), the mix would be at 100% on the machine. If you restart machines stays 100%:0%, that never happened before.

So finally, everything is back to normal.
Thanks a lot.
